STEVIA IS ANTI-CARIOGENIC. SO IS VITAMIN D, BUT THE LATTER HARDENS ENAMEL

One of the things that we all struggle with is getting the right information.  In the old days, if we didn't know something we'd rely on professionals--doctors, lawyers, dentists, teachers, and so forth.  Today, the internet has become a kind of equalizer, leveling the playing field of information, which puts an even greater premium on specialized information.  We'd like to think that this specialized information is more targeted as well to our individual circumstances.  But with greater information comes more competitors into a field.  And this can cause problems with getting the right, accurate, and actionable information.  Take dentistry, for instance.  For decades we were told that fluoride prevents cavities, and the science on this was so conclusive that municipal authorities began putting fluoride into the water supply of different cities around the country to the point that it is in almost every municipal water supply.  Then we learned that fluoride was bad for our health, that it was a neuro-toxin.  That can't be good.  Then companies and marketers began jumping on the non-fluoride bandwagon, convinced by the science and hopped up on propaganda, and to nearly ban fluoridate toothpaste and mouthwash from the marketplace.  The naysayers had won a victory.  But at what price?  Though we may not like having municipal committee members deciding for its citizens what we want in our water, the amount of fluoride in water is not enough to prevent cavities.  A lot of natural product supporters will cite this fact as proof for fluoride's poor performance in protecting teeth and gums.  But fluoride does have its place.   

I only wished I'd done my homework on dentistry when I was a kid.  Had I done so, I would have understood some of the terms that dentists threw around while my body was prone, my mouth agape, and twin female assistants took turns to warble flattering non-sense.  This image and these terms are a good start. 

So based on this picture, it looks like anything that threatens to unsocket your tooth is what you want to address immediately.  The gum tissue is what you want to nourish and clean.  Nutritionally speaking, vitamin C nourishes healthy gums.  But what about unhealthy gums, bleeding, or receding gums?  This is where the information gets overwhelming, and each person recommending this or that introduces an elaborate system for cleaning.  I hope that gum maintenance would be simple and elegant.  

GOAL #1: PRESERVE YOUR TEETH
We acquire 32 permanent, adult teeth.  KidsHealth explains that

By about age 12 or 13, most kids have lost all of their baby teeth and have a full set of permanent teeth. There are 32 permanent teeth in all — 12 more than the original set of baby teeth. Most people have four teeth (called wisdom teeth) grow in at the back of the mouth when they're between 17 and 25 years old.

How many teeth do you have today?  Following teenage cavities, braces, busted teeth from sports or rough play, we may only be left with 26 or 28 teeth at an early age.  And parents themselves don't know how many or what to do about lost teeth.  Can anything be done?  Since we don't know what is possible, it is better to adopt early a diet and hygiene that will keep as many of your permanent teeth as possible.  Remember that when you talk and when you smile, you show your teeth.  Make sure that that smile and that moving mouth during a speech or presentation is something to admire; least that it's not to frighten your audience. 

Periodontal Disease refers to the teeth and tooth structures inside and outside the tooth--gums, bone structure, and pulp inside the tooth.  One particular periodontal disease is gingivitis or swelling of the gums.  Swelling of the gums, or gingivitis, is different from a gingival recession, or receding gums.  So know your terms.  That doesn't answer for everything, but at least it will put you on a level footing with the dentist and keep him or her honest.  They don't really like their patients talking because questions and discussion eat into their scheduled list of patients for the day.  Better if you can put questions to them in advance.  
NUTRITIONAL SUPPORT FOR HEALTHY TEETH & GUMS Turns out that vitamin D is the main ingredient to help prevent cavities.  Oh, your dentist didn't tell you that?  Huh.  

from the Vitamin D Council, September 23, 2014.  Health Conditions: Dental Caries.  

DENTAL CARIES

WHAT ARE THEY?
Cavities.  

Dental caries, also known as tooth decay, is a tooth infection caused by bacteria that leads to a loss of the hard tissues of your teeth. It is one of the most common diseases in the world.  

THEIR CAUSE?
In a word, bacteria.  

Bacteria on the surface of teeth that can turn certain sugars into acids, which in turn can demineralize the hard tissues of your teeth. The bacteria form a sticky layer, which helps protect the bacteria from being removed by your immune system.

What produces corrosive bacteria?  Frequent snacking, sugary foods, and not enough saliva all increase your risk of developing dental caries.

PROVEN WAYS TO REDUCE BACTERIA
A few things.  Do all three.

1)  Vitamin D3. 

Research shows that vitamin D may help reduce the risk of dental caries in infants and younger children. Studies have shown that children with dental caries have lower levels of vitamin D.

More experiments are needed to know for sure if vitamin D can help to treat dental caries. Doctors and scientists don’t know yet whether taking a vitamin D supplement or getting more sun exposure, can help to prevent or treat dental caries.

Vitamin D will keep the enamel of your teeth hard.  The hardened enamel makes it more difficult for bacteria to corrode your teeth.  Vitamin D also keeps your immunity strong.  Saliva is part of your immunity that keeps bacteria in check.  

If you have cavities and want to take vitamin D, it is unlikely to make your cavities worse or cause you any harm, as long as you take less than 10,000 IU per day. However, it’s not proven that taking vitamin D will help treat dental caries or reduce your risk of developing dental caries.  What is proven is that vitamin D hardens enamel; the harder your enamel, the more difficult it is for bacteria to eat the surface of your teeth.  

2)  You'll need to use a fluoride toothpaste.  Fluoride-free toothpastes no added benefits to your health.  It's not the amount of fluoride in the toothpaste that you should worry about, for it is very little, but it is the accumulation of fluoride on your teeth that is protective.  You need protection from bacteria directly on the teeth themselves.  By hardening the enamel, fluoride protects from acid-forming bacteria.  

3)  Stop feeding yourself and your children sugar and sugary foods, like donuts, cookies, cereals, candy.  These produce acid-forming bacteria on the teeth.  If a sweetener is required, consume Stevia.  

Look, you've got to have a long-term outlook on your children's well-being.  Vitamin D, by the way, is extremely important, particularly during the winter months when more of our activities are indoors, cooking, watching TV, on the computer, or whatever.  Vitamin D isn't just beneficial for your children's teeth as important as that is for their confidence and social life, but vitamin D also is important for the bones in your mouth.  Vitamin D

has a critical role in enamel, dentin, and oral bone formation as ameloblasts and odontoblasts are target cells for 1,25-dihydroxyvitamin D, the active form of vitamin D. 

Vitamin D should be taken by the mother in a prenatal regimen, perinatal regimen (yes, babies can be given small amounts of vitamin D supplements), and post-natal.  Your efforts in your child's teeth will pay off years down the road.  He'll be happier, more confident.  

PERIODONTITIS
Here's a definition for Periodontitis.

Periodontitis, also referred to as gum disease, is a gum infection that damages the soft tissue and bone that surrounds the teeth. It can often result in gum recession and loosening of the teeth. It is the most common cause of tooth loss in the elderly.

Gingivitis is one form of periodontitis.  Know what gingivitis is.  It's inflammation of your gums.  Gingival recession means receding gums.  

For further explanation, check this out: 

Periodontitis is usually a painless, slowly progressing infectious disease in tooth-supporting tissues. Persistent bacterial colonization on the tooth surfaces leads to chronic inflammation in periodontal tissues. Periodontal inflammation results in gingival bleeding, pocket formation, destruction of alveolar bone, and eventually loss of teeth (33). Severe forms of periodontitis are relatively common, affecting up to 20% of the population worldwide (34).  

It's vitamin D to the rescue again, thanks to its anti-bacterial and anti-inflammatory properties

The pathogenesis of periodontitis is based on bacterial driven inflammation. Therefore, vitamin D has been hypothesized to decrease the risk of periodontitis by maintaining oral health by exerting its anti-inflammatory effects and reducing pathogenic bacteria.

Not only is periodontitis associated with low vitamin D, but so is low vitamin C.   10,000IUs of D and 500mgs of C should treat this condition.  The federal government of the United States collected dental data between 1988 and 1994 and found this: 

The study found a clear linear trend – the higher the vitamin D level, the lower the prevalence of gingivitis. There was no vitamin D level at which the relationship leveled off; the 10% of individuals with the highest levels of vitamin D (the group median was 45 ng/mL) had the lowest levels of gingivitis. 

A definition may not be enough to understand the seriousness of periodontitis disease.  It's serious.  Unfortunately, it's played down by dentists who either don't know how serious the disease is in connection with other vital organs or who are only interested in providing dental services--a tooth cleaning or filling--to remedy the disease in your mouth.  But it is serious stuff. 

Association of periodontal infection with organ systems like cardiovascular system, endocrine system, reproductive system and respiratory system makes periodontal infection a complex multiphase disease.

OIL PULLING REDUCES PLAQUE ACCUMULATION ON YOUR TEETH and, thus, ELIMINATES GINGIVITIS AND GUM RECESSION

Oil pulling with Sunflower oil, sesame seed oil, and coconut oil each reduce the amount of plaque on your teeth.  These reduce plaque accumulation on your teeth.  That, to me, seems like the number one benefit to oil pulling.  And because of its lauric acid, it seems that coconut oil could be the most effective of the three: sunflower oil, sesame seed oil, and coconut oil.  Odd that the study did not include olive oil.  How does it work?  

The oil film thus formed on the surface of the teeth and the gingiva can reduce plaque adhesion and bacterial co aggregation.⁵

TREATING GINGIVITIS with MOUTHWASH
Apparently, the best mouthwash to use is one that contains Chlorhexidine.

A 2017 study Trusted Source suggests chlorhexidine is the most effective antiseptic mouthwash to date. Dentists primarily prescribe it to treat the inflammation, swelling, and bleeding that comes with gingivitis.

Chlorhexidine is available in the United States under the brand names:

Paroex (GUM) [or PerioShield]

Peridex (3M)

PerioGard (Colgate)

There are a few unwanted side effects to using Chlorhexidine, so please read the link above where I obtained the information.

This video recommends a product called Gum Recession Rescue Tooth Powder, which sounds like a toothpaste.

WHAT ABOUT GUM SURGERY?  IS THAT THE WAY TO CURE GUM DISEASE? 
Hardly.  Gum surgery will only make gum disease worse.  Most surgeries in and around the body only compromise the tissue that is being cut.  David Kennedy, DDS, makes a good point.

So if you had an infected finger and went to the doctor and he/she got out a chopping knife to “fix” your problem you would likely run. If you go to a dentist and they recommend surgery I suggest you run as well. Cutting on gums merely accelerates the disease because it allows the bad guys to burrow deeper into tissue and bone and dose little to remove the offending bad guys. 

For gum recession and gingivitis, Andrew Saul recommends comfrey.  

DAVID KENNEDY, DDS, AMONG OTHERS, SUGGESTS USING A WATER PICK

HOW CAVITIES (or CARIES) DEVELOP
There are bacteria that live inside of your mouth that help break down foods and sugars that you eat. When dental caries develop, certain bacteria turn sugars into acids, which demineralize and destroy the hard tissues of the teeth. This demineralization and destruction of tooth tissue is tooth decay.

In children, dental caries are called early childhood caries (ECC). ECC, also known as bottle rot, is the presence of one or more decayed, missing, or filled tooth surfaces in any primary tooth in a child under three years of age¹.  

VITAMIN D TO THE RESCUE, LITERALLY 
Lacking Vitamin D has shown to be the main culprit in Early Childhood Caries.  Vitamin D keeps tooth enamel hard.  The way that works is that if you have adequate Vitamin D in your blood, the vitamin D makes the calcium in your blood more absorbent.  The result is that you get more calcium into the bone.  Know, too, that the cells that make up your teeth, the dentin and enamel and pulp, all have vitamin D receptors on the cells.  

You can give your child up to 1,000IUs of vitamin D per day.  Children playing outside in the front or backyard or up at the local elementary school with short sleeve shirts and shorts can get some vitamin D.  They get more vitamin D at the beach where more of their skin is exposed to sunlight.  Same for adults.  But the point of this is to make sure that you provide your child with adequate vitamin D for strong teeth that can better resist tooth decay.  And as your child becomes a teenager and a young adult, they'll feel better about themselves and their smile if their teeth are strong and healthy.  

Also, for mothers, you should be supplementing with vitamin D during pregnancy.  Don't be so arrogant about your physical powers to think, "Nah, I don't need no supplementation."  You do.  You need it for you AND for your baby's well-being.  Supplementing with vitamin D during pregnancy will prevent several unfortunate occurrences with your baby.  Truly. 

Low maternal vitamin D levels during pregnancy have been associated with a plethora of adverse neonatal outcomes, including small for gestational age and preterm births, detrimental effect on offspring bone and teeth development, and risk of infectious diseases. 

Without vitamin D, your child will be looking forward to regrettable and expensive procedures at the dentist's office as well.  Read for yourself:

Usually, treatment of caries involves removing the decay and then filling the space with restorative materials, such as porcelain or gold. In extreme cases, what is known as a “root canal” is needed if the pulp in your tooth dies from infection by bacteria.

MAINTENANCE

A professional cleaning every six months, brushing at least twice a day, and flossing daily can help you to prevent developing dental caries². Brushing your teeth removes plaque, which is a group of bacteria hidden under a protective surface on the teeth. As the amount of plaque increases, the tooth is more vulnerable to dental caries.

Nothing new here.  Except you might not know that using fluoride toothpaste is an added layer of protection for your enamel, dentin, and pulp.  There has been such a brouhaha over the hazards or toxicity of fluoride.  And yes it is an industrial solvent.  Yeah, so if you drink a gallon of the stuff, you're right, it is bad for you.  As to the fluoride in your municipal water supply, right again.  It's not nice that local governments put that in without your permission and then refuse to remove it after you're aware of it.  The government will always provide some rationale, usually false so that it serves some other purpose.  But the government's promise is that the fluoride is in the water supply to protect children's teeth.  Hardly.  The amount of fluoride in the water supply does not provide enough fluoride to protect your teeth.  Bill Sardi states it best

Fluoride helps harden dental enamel and thus makes teeth resistant to acid-forming bacteria that induce cavities.

Eating healthy can help reduce the risk of decay, such as reducing both the amount of and how often you consume sugars that are fermented by bacteria in the mouth. Increasing your intake of calcium is also often recommended to protect against dental caries because this can strengthen your teeth.

HOW CAN I AVOID ACID-PRODUCING FOODS?
Stop feeding yourself and your kids sugar.  

Start by reading this from Bill Sardi.  

Another major assault against dental decay would be for food processors and home cooking mothers to cease use of added sugars to foods that feed the growth of acid-forming bacteria in the mouth that are primarily responsible for dental decay.  In that regard, stevia leaf non-caloric sweeteners are considered to be “non-cariogenic” and would be a preferred form of sweetener for children whose taste buds are drawn to sweetened foods.  A stevia-based mouth rinse may even be superior to fluoride mouth rinses.

WHAT CAUSES DENTAL CARIES? 
Dental caries are caused by bacteria on the surface of teeth that can turn certain sugars into acids, which can demineralize the hard tissues of your teeth. The bacteria form a sticky layer, which helps protect the bacteria from being removed by your immune system.

Caries develop when your tooth enamel starts to demineralize by acids secreted by bacteria. Enamel is the thin, highly mineralized coating that makes up the visible part of teeth. The damage caused by the acids then spreads into the dentin, which is the softer tissue underneath the enamel. At this point, the tooth develops a cavity.

Before the cavity forms in the dentin, the process is reversible, but after it spreads to the dentin, it is not. The decay then spreads through the dentin to the layer below, called the pulp. The pulp is the part of the tooth that is made up of living connective tissue and its main purpose is to form dentin.

WHAT ARE THE SYMPTOMS OF DENTAL CARIES?
When caries begin to develop in your mouth, you may not be aware that you have the disease. As your tooth decays more and more, the most apparent symptom is pain in your tooth. This pain can be caused by sensitivity to heat and cold or consumption of sweet foods and drinks.

When your tooth is severely decayed, a toothache can develop which means the pain will become constant.

HOW COMMON ARE DENTAL CARIES? 
About 92% of adults aged 20 to 64 years old have had dental caries in their permanent teeth. In this same group, there is an average of about 3 decayed or missing permanent teeth caused by dental caries³.

About 92% of adults age 20 to 64 years old have had dental caries in their permanent teeth.

Medical conditions that reduce the amount of saliva in your mouth, such as Sjögren’s syndrome, diabetes, and sarcoidosis, can increase your risk of developing caries. Certain medications such as antihistamines and antidepressants can also reduce the amount of saliva in your mouth and increase your risk of caries. Saliva contains antimicrobial compounds, as well as minerals that neutralize the acids created by bacteria and help to protect and restore the teeth.

There are certain things that can increase your risk for dental caries, such as⁴:

Tooth location and surface. Caries are most commonly found on incisors, canines, premolars, and fissure sites in molars.
Foods that cling to the teeth, such as candy or chocolate.
Frequent snacking and sipping on sugary drinks.
Bedtime infant feeding.
Inadequate brushing of teeth.
Dry mouth.
Heartburn.

WHAT IS THE LINK BETWEEN VITAMIN D AND DENTAL CARIES? 
Enamel is the most mineralized substance in the human body. It is made up of mostly calcium and phosphate. Vitamin D is important for increasing the absorption of calcium and phosphate from the food you eat.

Increasing the absorption of calcium and phosphate can improve the strength of your teeth and their ability to fight demineralization from bacteria.

Vitamin D receptors are found on cells in your immune system and in your teeth. Vitamin D can bind to these receptors and increase the amount of good antimicrobial proteins in your body which help to fight the bacteria that cause dental caries⁵.

In addition, the cells in the teeth that form dentin and enamel contain vitamin D receptors, meaning that vitamin D may play a role in their functioning.

WHAT DOES THE RESEARCH SAY, IN GENERAL, ABOUT DENTAL CARIES?
Some studies show that dental caries are most common in late winter and early spring, when vitamin D levels are likely to be at their lowest⁶.

Many studies have found that geographic location and sun exposure are related to dental caries. People living closer to the equator with greater amounts of sun exposure are less likely to develop dental caries⁷.

Mothers of children have lower vitamin D levels during pregnancy than mothers whose children don't have caries.

Most of the research on vitamin D and dental caries has looked at ECC and severe ECC.

Children with ECC tend to have lower vitamin D levels than healthy children^8,9. Mothers of children with ECC have lower vitamin D levels during pregnancy than mothers whose children don’t have caries¹⁰.

Some experiments have found that giving a mother vitamin D supplements while she is pregnant can reduce the rate of dental enamel defects in their children. Defects in dental enamel increase the risk of a child developing dental caries¹¹.

Studies that give people vitamin D supplements to prevent caries have found that vitamin D is effective at preventing the development of caries¹².

WHAT DOES RECENT RESEARCH SAY ABOUT DENTAL CARIES?
A study published in 2014¹⁰ looked at the vitamin D levels of pregnant Canadian women and whether or not their children developed ECC in their first year of life. They found that:

Mothers of children who developed ECC had lower vitamin D levels compared to mothers of children who did not develop ECC.

Children with ECC had more dental caries if their mothers had low vitamin D levels during pregnancy.

The researchers conclude that the vitamin D levels of a mother during pregnancy may relate to their children’s risk of developing ECC.

A Canadian study from 2013⁹ looked at preschool children with severe ECC and children of the same age without dental caries. The researchers measured the children’s vitamin D levels and the parents answered questions on their child’s nutritional habits, oral health, and family information. They found that:

Children with severe ECC had lower vitamin D levels than healthy children.

Winter season was also related to low vitamin D levels in children with severe ECC.

A 2013 review from the United States¹² looked at many studies that measured the effects of UV therapy and vitamin D supplementation in preventing dental caries. The main findings were:

Taking vitamin D supplements resulted in a 47% reduced rate of dental caries.

Taking vitamin D supplements had no effect on caries in those older than 13 years old, especially in girls.

The researchers concluded that taking vitamin D supplements may help protect against developing dental caries in children younger than 13 years old.

KEY POINTS FROM THE RESEARCH
Dental caries are more common in late winter and early spring, which is when vitamin D levels tend to be lower.

Children with severe ECC have lower vitamin D levels compared to children without caries.

Mothers with low vitamin D levels are more likely to give birth to children who develop dental caries.

Vitamin D supplementation may help reduce the risk of developing dental caries.

WHAT DOES THIS MEAN FOR ME?
Research has shown that there is a link between vitamin D and dental caries.

Vitamin D can help strengthen your teeth's resistance to bacteria by helping to absorb calcium and phosphate.  

Vitamin D can help strengthen your teeth’s resistance to bacteria by helping to absorb calcium and phosphate. Vitamin D also increases the amount of good antimicrobial proteins which can destroy the bacteria that cause caries.

Research shows that higher vitamin D levels in pregnancy and early life can help to reduce the risk of dental caries.

However, more experiments are needed to know for sure if vitamin D is effective in treating dental caries. Doctors and scientists don’t know yet for sure whether or not taking a vitamin D supplement or getting more sun exposure, can help to prevent or treat dental caries.

If you have dental caries and want to take vitamin D, it is unlikely to make your dental caries worse or cause you any harm, as long as you take less than 10,000 IU per day. However, it’s not proven that taking vitamin D will help you prevent or treat dental caries.

You shouldn’t take vitamin D in place of the treatment medications for your dental caries. Talk to your doctor for more advice about taking supplements.  

HALITOSIS
Is bad breath.  But there are multiple sources for his.  NCBI describes one kind of halitosis: 

Physiological halitosis (foul morning breath, morning halitosis) is caused by stagnation of saliva and putrefaction of entrapped food particles and desquamated epithelial cells by the accumulation of bacteria on the dorsum of the tongue, recognized clinically as coated tongue and decrease in frequent liquid intake. 

Tongue scrapers are one way to remove 75% of the bacteria that causes halitosis.  So that's good.

Tongue scrapers are shaped according to the anatomy of the tongue and reduces 75% VSCs compared to only 45% using a toothbrush. 

Failure to floss leads to halitosis.

5 Ways Corrective Lenses Break Down your Eyesight and How to Improve your Vision Naturally

by Marco Torres

Optometrists just like much of the medical community are fixated on short-term solutions which don't address the root cause of problems. Few optometrists will admit and the greatest majority are unaware that glasses and contacts are almost guaranteed to destroy your eyesight over time.Unfortunately, they're not trained on natural and preventative solutions that improve vision in the long-term because they simply do not understand the way the eye works. Contrary to popular belief, your vision doesn't have to decline over time. With regular exercise of the muscles that control your eye movements and visual acuity, you can reduce eyestrain and maintain or even improve your vision without any destructive correctional conventions such as laser surgery, glasses or contact lenses.

Practically everyone these days suffers from some form of refractive error. Yet we are told that for these ills, which are not only so inconvenient, but often so distressing and dangerous, there is not only no cure, and no palliatives except those optic crutches known as eyeglasses or contacts, but, under modern conditions of life, practically no prevention.

Few if any optometrists even understand the role of nutrition of even breast milk in eye development. Breast-fed children are significantly more likely to do well in measures of stereoscopic vision than are those who received formula during in infancy.

With one accord ophthalmologists tell us that the visual organ of man was never intended for the uses to which it is now put. Eons before there were any schools or printing presses, electric lights or moving pictures, its evolution was complete. In those days it served the needs of the human animal perfectly. Man was a hunter, a herdsman, a farmer, a fighter. He needed, we are told, mainly distant vision; and since the eye at rest is adjusted for distant vision, sight is supposed to have been ordinarily as passive as the perception of sound, requiring no muscular action whatever. Near vision, it is assumed, was the exception, necessitating a muscular adjustment of such short duration that it was accomplished without placing any appreciable burden upon the mechanism of accommodation.

While primitive man appears to have suffered little from defects of vision, it is safe to say that of persons over twenty-one living under civilized conditions nine out of every ten have imperfect sight, and as the age increases the proportion increases, until at forty it is almost impossible to find a person free from visual defects. Voluminous statistics are available to prove these assertions.

Roughly 2.5 billion people have perfect 20/20 vision. For the other two-thirds, more than 80% of vision problems worldwide are preventable and even curable. In developed nations, more than 90% of aging related deterioration of vision before the age of 50 is due to diet and the daily use of corrective lenses. Meaning the more people lack nutrition and the more frequent the use of glasses or contact lenses, the worse vision will become impaired.

5 WAYS CORRECTIVE LENSES BREAK DOWN YOUR EYESIGHT 

1. Corrective Lenses Don't Correct, They Distort

The fact that glasses or contact lenses cannot improve sight to normal can be very simply demonstrated by looking at any color through a strong convex or concave glass. It will be noted that the color is always less intense than when seen with the naked eye; and since the perception of form depends upon the perception of color, it follows that both color and form must be less distinctly seen with glasses than without them. Even plane glass lowers the vision both for color and form, as everyone knows who has ever looked out of a window. Women who wear glasses for minor defects of vision often observe that they are made more or less color-blind by them, and in a shop one may note that they remove them when they want to match samples. If the sight is seriously defective, the color may be seen better with glasses than without them.

2. Corrective Lenses Injure The Eye

That glasses or contact lenses must injure the eye is evident through the principal of refraction. One cannot see through them unless one produces the degree of refractive error which they are designed to correct. But refractive errors, in the eye which is left to itself, are never constant. If one secures good vision by the aid of concave, or convex, or astigmatic lenses, therefore, it means that one is maintaining constantly a degree of refractive error which otherwise would not be maintained constantly. It is only to be expected that this should make the condition worse, and it is a matter of common experience that it does. After people once begin to wear glasses their strength, in most cases, has to be steadily increased in order to maintain the degree of visual acuity secured by the aid of the first pair. Persons with presbyopia who put on glasses because they cannot read fine print too often find that after they have worn them for a time they cannot, without their aid, read the larger print that was perfectly plain to them before. A person with myopia of 20/70 who puts on glasses giving him a vision of 20/20 may find that in a week's time his unaided vision has declined to 20/200, and we have the testimony of Dr. Sidler-Huguenin, of Zurich that of the thousands of myopes treated by him the majority grew steadily worse, in spite of all the skill he could apply to the fitting of glasses for them. When people break their glasses and go without them for a week or two, they frequently observe that their sight has improved. As a matter of fact the sight always improves, to a greater or less degree, when glasses are discarded, although the fact may not always be noted.

3. Corrective Lenses Condition The Eyes To Fail

That the human eye resents glasses is a fact which no one would attempt to deny. Every oculist knows that patients have to "get used" to them, and that sometimes they never succeed in doing so. Patients with high degrees of myopia and hypermetropia have great difficulty in accustoming themselves to the full correction, and often are never able to do so. The strong concave glasses required by myopes of high degree make all objects seem much smaller than they really are, while convex glasses enlarge them. - These are unpleasantnesses that cannot be overcome. Patients with high degrees of astigmatism suffer some very disagreeable sensations when they first put on glasses, for which reason they are warned by one of the "Conservation of Vision" leaflets published by the Council on Health and Public Instruction of the American Medical Association to "get used to them at home before venturing where a misstep might cause a serious accident." Usually these difficulties are overcome, but often they are not, and it sometimes happens that those who get on fairly well with their glasses in the daytime never succeeded in getting used to them at night.

4. All Corrective Lenses Contract The Field of Vision

All glasses contract the field of vision to a greater or less degree. Even with very weak glasses patients are unable to see distinctly unless they look through the center of the lenses, with the frames at right angles to the line of vision; and not only is their vision lowered if they fail to do this, but annoying nervous symptoms, such as dizziness and headache, are sometimes produced. Therefore they are unable to turn their eyes freely in different directions. It is true that glasses are now ground in such a way that it is theoretically possible to look through them at any angle, but practically they seldom accomplish the desired result.

5. Corrective Lenses Do Not Address Acuity Improvement

It is important to note the absence of statistical correlation between refractive changes and acuity improvements, which implies that other factors besides refractive changes contributed to the observed acuity improvements. Is it not only the sharpness of the retinal focus within the eye that improves acuity. Acuity improvement is a process involving several possible physiological and cerebral mechanisms. The most striking changes occur in visual acuity. Physiological changes are largely responsible for much of these improvements and these can never be addressed by corrective lenses and hence does not address the problem. Although optometrists use refraction measurements, they do not provide enough information about whether the reductions in refractive error are due to axial, corneal, or lenticular changes.

How To Keep Your Eyes Naturally Healthy

Perhaps the single greatest reason why people in today's society suffer from chronic eyestrain and deteriorating vision is the amount of time that is spent staring at computer monitors and television screens.

Your eyes are designed to move regularly. Frequent movement of your eyes is what promotes optimal blood flow and nerve tone to your eyes and the six muscles that control your eye movements.

What follows are several simple eye exercises that you can do on a regular basis to keep your eyes and vision as healthy as possible:

Look as far to your right as possible for 3-5 seconds, then as far to your left as possible for 3-5 seconds. Rest for a few seconds, then repeat this sequence several times.

Look as far up as possible for 3-5 seconds, then look as far down as possible for 3-5 seconds. Rest for a few seconds, then repeat this sequence several times.

Slowly roll your eyes in a circle, first clockwise, then counter-clockwise. Rest for a few seconds, then repeat this sequence several times. Be sure to roll slowly - it should take at least 3 seconds for you to roll your eyes in a full circle.

Hold a pen in front of you, about an arm's length away. Focus your vision on the tip of your pen for 3-5 seconds, then shift the focus of your vision to an object that is farther away for 3-5 seconds. The greater the distance between your pen and the distant object, the better. If you are indoors, look out a window to find a distant object to focus your vision on. Repeat this sequence of going back and forth between your pen and a distant object several times.

Just for interest's sake, this exercise is used by some professional baseball players to optimize visual acuity, which is essential for the hand-eye coordination that is needed to play pro ball.

Please note that all of these exercises should be done with your eyes, not your head and neck. With this in mind, keep your head and neck still while you take your eyes through the movements described above.

Relearning to See: Improve Your Eyesight - Naturally! is an outstanding book that offers a comprehensive array of exercises and information that can help you support your vision. And if you wear eyeglasses or contacts, following the guidance provided in this book may actually help you do away with your prescription eye wear or at the very least, help prevent deterioration of your visual acuity as you age.

Beyond doing the exercises described above on a regular basis, another way to reduce eyestrain and promote your best vision is to use your fingers to apply gentle pressure to three acupressure points that can help promote healthy blood flow to your eyes and the muscles that surround your eyes.

Keep Blinking

Frequent and gentle blinking is essential to maintaining healthy eyes and optimal vision because it allows your eyelids to keep your eyes coated with three beneficial layers of tears:

The first layer of tears lies right up against the whites of your eyes, and provides an even coat of protein-rich moisture for the second layer to adhere to.

The middle watery layer helps to wash away foreign debris. It also nourishes the cornea of your eyes with minerals, a variety of proteins, and moisture.

The third outer layer of tears is somewhat oily. It serves to prevent the middle watery layer from evaporating quickly, and provides needed lubrication between your eyes and your eyelids.

If your eyes are not regularly coated with the three layers of tears described above, they will be deprived of ongoing nourishment and cleansing, and they will be unnecessarily strained.

One of the reasons why many of us don't blink as often as we should is that we don't see frequent blinking in mainstream media. Actors and anchor-people are typically trained to blink as infrequently as possible, so when we take in most forms of media, our subconscious minds learn that it isn't normal to blink frequently.

To optimally support your eyes and vision, it's best to blink softly every two to four seconds, which translates to about fifteen to thirty blinks per minute. By consciously making an effort to softly blink at this rate, over time, your body will turn your conscious efforts into a subconscious habit.

If you're thinking that such frequent blinking will make reading a book or viewing a movie uncomfortable, give it a try and you'll see right away that it doesn't take away from these experiences at all.

Here are some notes on blinking to promote optimal eye health and vision:

A soft and natural blink should occur like the light flap of the wings of a butterfly - this is a good image to visualize as you make an effort to blink softly every two to four seconds.

You should blink regularly during all activities, including reading, working on the computer, and viewing a TV program or film.

Contact lenses can discourage frequent blinking because the back side of your eyelids is not designed to rub over an artificial surface. This is one of several good reasons why contact lenses should be avoided whenever possible.

Some yoga and meditation instructors suggest doing exercises that involve fixating your vision on one object - such as the flame of a candle - and doing your best not to blink. Frequent blinking while doing this type of exercise doesn't take away from the ability to experience inner stillness.

More Visual Training

The following techniques, then, are based on these premises: First, that the art of seeing-like other fundamental skills such as talking, walking, and using one's hands-is acquired. Second, this skill is normally learned through unconscious self-instruction in childhood. Third, for many of us in today's pressure-packed world, the only way to keep perfect sight is to practice techniques of conscious eye relaxation. Finally, if the exercises are performed correctly for a sufficient length of time-in conjunction with a proper diet and a physical conditioning program-eyesight will show permanent improvement. (The corollary to this is that the stronger the lenses you wear now-and the longer the time that you've worn them-the more time and effort you'll have to put forth to achieve better vision.)

It's best to "palm" while sitting or lying on the floor, with your elbows propped on a cushioned surface. Close your eyes and then cover them with the palms of your hands, crossing the fingers of one hand over those of the other on your forehead. Don't, however, apply any pressure on the lids with your palms. Ideally, you'll "see" a field of intense blackness, which indicates a state of perfect relaxation. If instead you witness illusions of light, bright color, or patches of gray, you're tense to some degree. However, don't concentrate on trying to "see" blackness, as the effort itself will produce strain. Rather, passively visualize a pleasant memory-one that helps ease your mind-while keeping your shoulders and neck relaxed. The more frequent and lengthy the periods of palming, the more likely you are to school your eyes to reduce muscle tension, with subsequent benefit to your sight.

Pinhole Glasses

Pinhole glasses, also known as stenopeic glasses, are eyeglasses with a series of pinhole-sized perforations filling an opaque sheet of plastic in place of each lens. Similar to the workings of a pinhole camera, each perforation allows only a very narrow beam of light to enter the eye which reduces the size of the circle of confusion on the retina and increases depth of field. In eyes with refractive error, the result is claimed to be a clearer image.

Unlike conventional prescription glasses, pinhole glasses produce an image without the pincushion effect around the edges (which makes straight lines appear curved).

After prolonged use, the plastic grating should become easy to ignore. With certain eye exercises such as those below, pinhole glasses can permanently improve eyesight. Skeptics argue that no scientific evidence has been found to support them. Due to a lack of formal clinical studies to substantiate this type of claim by companies selling pinhole glasses, this type of claim is no longer allowed to be made in the United States under the terms of a legal settlement with the Federal Trade Commission, however empirical evidence suggests they do work.

Swinging

This whole-body exercise improves vision, relieves fatigue and stress, and increases the mobility of the eyes. Stand looking straight ahead, with your feet positioned about 12 inches apart. Now, rotate your body-head, trunk, and all-to the left, throwing your weight onto your left foot while you allow your right heel to rise from the floor. Keep your shoulders and neck straight. When you swing to the opposite side, shifting your weight to your other foot, your eyes will cover a 180 degree arc.

Absolutely no attempt should be made to focus your sight on anything. Just maintain an attitude of passive relaxation, making about 30 of these "arcs" per minute. You should do this exercise twice daily, completing the swing from side to side 100 times. By doing your swings right before bedtime, you'll prevent eyestrain from occurring during sleep.

Sunning

Although there's no scientific evidence available to prove that sunning helps vision, many people who have tried it testify to its benefits, particularly those whose eyes have become oversensitive to light.

All sunning should be done with the eyes closed. Sit or stand in the sunlight, face relaxed, and let the rays of the sun penetrate and ease the tension in your eyelids. This is a good way to start off the day, and even a few minutes will help. To avoid possible strain on your eyes, rotate your head slightly from side to side or move it as if you were using your nose to draw a circle around the sun . . . breathe deeply and don't squint.

Central Fixation

Central fixation refers to the fact that-since the central portion of the retina is the point of most acute vision-the eye sees only one small part of any object sharply, with all the other areas being slightly blurred. When you look at a thing, your eye shifts very rapidly over it to achieve the illusion of clearly seeing the entire object at once. To demonstrate this fact, look at an object, focusing on its topmost part. Without actually moving your focus downward, try to "see" the bottom of the object. You'll find that its lower details don't appear to be sharp.

A problem-free eye shifts quite rapidly and unconsciously while it is observing. People with imperfect vision often try to see a large part of the visual field at once, all areas equally well simultaneously, without moving their eyes. This puts considerable strain on the eye . . . and also on the brain, the organ that actually has to integrate what you see.

To correct this tendency, it's important to develop your central fixation by teaching your eyes that it's "acceptable" to see only one point clearly at a time. The orbs must learn to move and refocus rapidly, rather than straining to see an entire object at one sighting. You can do this by studying an eye chart, training yourself to look at the top of a letter on the chart while "accepting" an unfocused image of its bottom (and vice versa). When you can accomplish this easily, your eyes will be relaxed, and your vision will be improved.

Most of us rely on our vision to supply 80% to 90% of the information we process about the world. Our sight affects the way that we think and, in addition, the way we think affects our sight. (If you don't believe the latter statement, just remember that you actually see the world upside down...but your mind "inverts" the images so that they make sense!) Taking good care of this dominant sense organ, then, is obviously important. Will a regimen of eye-training exercises help you do that...and even improve defective vision? There's only one way to answer that question for yourself.
