Pinhole Glasses Re-visited

Exercise your eyes while you read or watch TV

Long-sighted people can do this exercise while focusing close up – doing things like reading. Short-sighted people get the benefit from focusing at a distance, eg. Watching TV


15 minutes a day
The major cause of the long-sightedness that comes with advancing years is a weakening of the focusing muscles that control the eye’s lens. Looking through the tiny holes forces the eye muscles to exercise. Just 15-20 minutes a day bring a noticeable improvement within a couple of weeks.

 

Many of us think that as we grow older our eyesight is destined to deteriorate. We talk about "tired" or "old" eyes as if we are fated to have the gift of vision taken from us simply because we have aged.
But, as with most conventional wisdom, there is an element of truth to the notion that age-related processes can affect our eyesight.

A good understanding of vision loss requires a brief foray into the basic structure of the eye. Although it might be considered a cliché, it is still useful to compare the eye to a video camera. Thus, as light enters the eye--or the camera--it travels through four main structures. By understanding this basic eye anatomy we can begin to understand the ways in which the light signal can be degraded or distorted, resulting in poor vision.

The entry point for light is the cornea, the transparent tissue in the very front of the eye that functions as the window through which all light has to pass on its way to forming a visual perception. Next, the light signal encounters the lens, which focuses it finely on the third structure of the eye: the retina. The retina is analogous to the film in the back of the camera. It is on the retina that the light is converted into a neural signal that is ultimately interpreted by the brain as an image. Finally, the optic nerve, which carries these signals to the brain, functions like a cable that connects the video camera to the television screen. The deterioration of our vision with age is invariably the result of a problem with one of these four structures.

Bad eyesight is known to be caused by too much strain in the eye muscles. Conventional glasses only serve to increase the problem. When your eyes are starting to have a problem focusing, using corrective lenses simply compensates for the error – they don’t train or exercise the eye. That is why people who wear glasses frequently have to wear stronger and stronger glasses as time goes by.

Part of the Downhill Slide

When you wear prescription glasses you fall into a trap. You no longer fully use either the focusing muscles or your photoreceptors within your retina. The important "ciliary muscles" begin to weaken, requiring visits to your eye doctor for stronger and stronger lenses.

 

The fix that fails kids' eyes
23 November 2002
Andy Coghlan Michael Le Page
Magazine issue 2370
The standard prescription for correcting children's short sight actually seems to make their eyes deteriorate faster. And it has been used routinely for decades
MILLIONS of people worldwide may have worse eyesight and even be more likely to go blind because of a long-held but misguided idea about how to correct short-sightedness. A study intended to confirm the theory has instead been stopped because the children's eyesight was getting worse, New Scientist has learned.

For decades, many optometrists have been routinely "undercorrecting" short-sightedness, or myopia, when prescribing glasses or contact lenses. "What was done was done with the best of intentions," says optometrist Daniel O'Leary of Anglia Polytechnic University in Cambridge, England. Indeed, his study of 94 children in Malaysia sought to prove the value of undercorrection. Instead, it showed the opposite.

While the number of children involved was small, amazingly it is the largest and most rigorous study to date. "The study was meant to run for three years but after two years, when we found out we were making the children's eyes ...

OKAY LETS TALK ABOUT AN ALTERNATIVE

Pinhole Glasses

Some advantages that pinholes have over prescription glasses:

As we get into our 40's and 50's and presbyopia (inability to focus close) develops, pinholes provide a simple and inexpensive solution for reading or other close work.
Bifocals or trifocals are designed to provide a clear image only at fixed distances. Pinholes provide an improved image at ALL distances. In many applications, such as alternating between watching TV and reading, they can easily take the place of those very expensive prescription lenses that are so lucrative for the anti-consumer eye doctor/optical industry alliance.
Multi-focal lenses provide a continuously variable curve that is supposed to give good vision at all distances. In reality, the distortion on either side of the center line is considerable and often too great for comfortable use. Pinholes eliminate this problem.
There is no need to continually throw away old glasses and buy new, stronger ones. Unless the pinholes get broken, they can be used an entire lifetime.
While pinholes are not as cheap as off-the-rack reading glasses, they are considerable cheaper than individual prescription glasses. For example, a person who is a little nearsighted but only needs clear distant vision for occasional TV viewing would find pinholes a cheaper solution than prescription glasses.
Off-the-rack reading glasses have the same lens power in each lens. Some people find these cheap glasses unsuitable because the refractive error in each eye is not the same. Pinholes are ideal for such people because these glasses do not require a similar refractive error in each eye.
There is a pincushion effect when looking through the edges of prescription glasses. That is, straight lines appear curved. This disturbing effect does not occur with pinholes.
When you lay prescription glasses down improperly, they can easily get scratched at the center of the lens, the very area you have to look through. Scratching pinholes has no effect on their performance.
Pinholes do not have to be cleaned of fingerprints and other marks that affect vision.
Many parents will not allow their children to use bifocals to reduce the stress of close work because such glasses are for "old people." Pinholes are an easier thing to accept because they are the same for all ages.
Many people who have had corneal surgery find that their night vision has permanently deteriorated. Glare is a problem. They see halos and "starbursts" around lights. Even in normal home lighting they have problems so that they get in the habit of turning on as many lights as possible in order to get a small pupil and reduce the visual problems. Pinholes, either conventional or Snap-ons, can deliver the same small pupil without increasing the electric bill.
Children with special needs often use only their peripheral vision, and pinhole glasses help them concentrate on detail better. It has been found that the pinhole glasses help improve acuity and central macular vision. One nationwide organization that deals in child development uses pinhole glasses on a regular basis for this purpose.
Aniridia is the complete or partial absence of the iris; polycoria is having more than one pupil in a single iris; and albinism is the lack of normal pigmentation. All of these abnormalities may be aided with pinhole lenses.
In cases of retinal separation, unnecessary motion of the eyeballs should be avoided. This can be accomplished by blocking all but the central pinholes, forcing the user to turn the head rather than the eyes.


pinhole glasses help your eyes focus and in so
doing exercise tired eye muscles.
In turn your eye’s focussing ability improves.

 

NATURAL VISION IMPROVEMENT PINHOLE GLASSES

Discover how to relax your tired eyes and enjoy reading the healthy way
without prescription glasses.

Inexpensive - No Prescription Required.
        Pinhole Glasses are inexpensive when compared to prescription glasses. Now you can refresh your tired eye muscles and keep the eyes from staring - a common cause for eye fatigue.

How They Work.
        Pinholes provide an infinite depth of focus so that even when the eye is not correctly focused, objects will appear as if in focus. Importantly they eliminate scattering of light to the retina and hence improve vision.
        The idea behind pin-hole glasses is not new. It was known centuries ago and was used before the advent of glass lenses. The reason they work is simple. "Light passing through a small hole (or holes) is restricted to rays coming straight from the viewed object; these rays do not need focusing to bring them to a point," according to Drs. Russell S. Worrall and Jacob Nevyas in The Eye Exorcisors published in The Health Robbers.
        Just look through any pin-hole and you'll see what they mean. When you do this, blurred images become focused. This is because the amount of peripheral light rays (which are responsible for blurring) is reduced. With appropriately spaced multiple pin-holes, you'll get clear straight vision without the difficulty of concentrating on a single hole. Regular use of these special pinhole glasses helps exercise eye muscles and helps eyes relax at the end of a tiring day and thus has a beneficial effect. Particularly useful for those who spend a great deal of time looking at computer and/or TV screens, Pinhole Glasses help retrain your eye muscles, just as other forms of exercise retrain muscles elsewhere.

I have very poor vision in my left eye and see nothing but a blur from my right eye. When I put on the pinholes on, the vision in both eyes improves greatly. The improvement is especially remarkable in my right eye. With my left eye closed, I can now see the letters on the cereal box across the table, for example. It is just amazing what these simple glasses can do. It is also amazing that my doctor didn't tell me about this. Thanks for letting me try them. Fran H., Plum Boro, Pittsburgh, PA 11/22/99

 

MORE ON PINHOLE GLASSES
        Pinhole glasses (also known as stenopeic glasses) are not made of glass at all but of an opaque substance such as metal or plastic. The user looks through any of the many small holes in the material. These holes have the effect of reducing the width of the bundle of diverging rays (called a "pencil of light") coming from each point on the viewed object. Normally, the full opening of the pupil admits light. It is the improper bending of the outermost rays in that pencil of light which causes refractive errors such as myopia, hyperopia (farsightedness), presbyopia (diminished accommodative range with age) and astigmatism to be noticeable. Pinholes can bring about clearer vision in all these conditions.
        By blocking these peripheral rays, and only letting into the eye those rays which pass through the center portion of the pupil, any refractive error in the lens or cornea is not noticed as much. Of course, in the case of myopia, let's not blame the lens or cornea. It is the abnormal lengthening of the eye which is the problem.
        The pupil may be wide open, but only the central portion is receiving light. The improvement in visual acuity can be striking. Look at this Converging Lens and imagine it as the lens of the eye.
All the light rays within the outermost yellow lines make up a pencil of light. Imagine that this bundle of light passes through one of the pinholes while rays outside this area are blocked. You will see that the eye does not need to deal with the rays that would need the most bending. It is said that Scheiner first described this effect in 1573. Those who are familiar with cameras will recognize that this is the same principle used to increase the depth of focus by decreasing the aperture.
        An easy way to demonstrate this is to make a fist and put it up to one eye while closing the other eye. Open the fist just enough to create a small hole to look through. If you have a refractive error, you should see clearer this way. This same improvement in the vision takes place when someone squints to see more clearly. The upper and lower eyelids cut off the rays that would normally enter the top and bottom of the pupil and the vision improves somewhat. Since there is no similar way to cut off rays entering the sides of the pupil, these rays still contribute to the blurred vision. Looking through pinhole glasses instead of squinting cuts off the peripheral rays from all sides. Since the holes themselves are so close to the eye, they are greatly out of focus and are not as disturbing as one might think.

        After a period of getting used to them, the brain tends to ignore their presence. Also of interest is that the farther away the viewed object is, the less the pinholes are noticed. The honeycomb effect of the holes is easily noticeable when viewing a book held close to the eyes, because the eyes are focused just a short distance in front of the glasses. When looking at a distant TV, however, the holes are hardly visible at all since the eyes are focused much farther away. Also, because of the distance, you can view the entire TV screen through one hole, an obvious benefit.

‘Tests indicate that, because the eye has to focus on a fixed point (your computer screen), after a few minutes, heart rate (one of the best indications of stress) can increase by around 5 per cent. This is enough to cause tension in the shoulders and lead to headaches.

‘Because pinholes are smaller than the eye’s normal pupil size they relax the eye without losing the clarity of the image. The reduced tension in the eye is felt immediately and heart rate returns to normal within minutes,’ says Grunwald.

Peter Grunwald is a world-renowned expert on eyesight, regularly lecturing in 12 different countries, ‘very few people are born with bad eyesight, most bad eyesight is acquired’ he says.

 

        One limitation of pinhole glasses is that blocking some of the light makes it more important than usual to have good lighting on the viewed object. When looking at television this is not a problem since the set makes its own light. When reading, a good lamp should be provided nearby. Another limitation is that peripheral vision is diminished, so they should not be used for driving or similar activities involving motion. As with any glasses, even sunglasses, they should not be used to stare at the sun, thinking that no harm can be done.

        We do not claim that pinholes can replace prescription glasses in every situation. Just as it would be risky to wear ordinary glasses in situations where they could be broken and damage the eyes, there are situations where using pinholes instead of prescription glasses is not advisable. Use common sense and only wear the pinholes when the limited view does not pose a risk. No one who manufacturers or sells pinhole glasses can be held liable for misuse of these glasses since this is beyond their control.
        While pinholes are not as cheap as off-the-rack reading glasses, they are considerable cheaper than individual prescription glasses. For example, a person who is a little nearsighted but only needs clear distant vision for occasional TV viewing would find pinholes a cheaper solution than prescription glasses. There is no need to continually throw away old pairs and buy new, stronger ones. Unless the pinholes break, they can be used an entire lifetime.
        The native people of Alaska have long used this principle by wearing glasses with narrow slits to look through, thus blocking out much of the glare from the sunshine reflecting off the snow and ice. Anyone who remains in this environment for long periods during the summer without protection can suffer from snow blindness. This painful condition forces the person to discontinue the use of the eyes until healing can take place. This is nature's way of protecting the eyes from permanent damage.

        Pinhole glasses are an excellent substitute for expensive bifocal glasses. They can provide good vision for any distance, both far and near.

        There is a pincushion effect when looking through the edges of prescription glasses. That is, straight lines appear curved. This disturbing effect does not occur with pinholes.
        When you lay prescription glasses down improperly, they can easily get scratched at the center of the lens, the very area you have to look through. Scratching pinholes has no effect on their performance.
        Some people with cataracts have given testimonials that they see better with pinholes because the scattering of the light is diminished. A cataract is actually one or more opacities in the lens that do not allow the light to pass through properly but instead cause it to scatter. By cutting off the peripheral rays, pinholes could reduce some of this scattering and improve the vision. The only way to determine if an individual will benefit in this way is to try the glasses.

        However, the most important use for pinholes is in an application that has until now been totally ignored, Myopia Prevention.
        When a person's eye has become abnormally long due to excessive close work, the outermost rays come to a focus in front of the retina and cause the blurred vision. Imagine for a moment the common situation where a child begins to develop myopia and can't see the blackboard clearly. The usual solution of giving the child minus lenses is disastrous. But suppose the child has a pair of pinholes and puts them on just to look at the blackboard.
        A large area of the blackboard can be seen through just one hole. The cost and the risk involved with minus lenses has been avoided entirely. Suppose the child also leaves them on when reading or looking at a computer screen. This could help greatly in preventing myopia since the accommodative effort is reduced. For those children whose natural farsightedness has diminished to around +0.5 diopters and are on the verge of moving into myopia, sitting down at the school desk and putting on the pinholes should be almost simultaneous events.
        Many children might need nothing more than this to insure that they do not develop myopia. Schoolteachers should have several pairs on hand to lend to the students who have difficulty seeing the blackboard.
        Can you imagine what the eye doctors and optical industry think about this inexpensive solution? The fact that you don't find pinholes in the optical stores and eye doctors don't recommend them should give you a hint. In fact, it is just this opposition that has resulted in government persecution of those who sold such glasses in the past. It is both enlightening and appalling to look at some of "these cases".

In 1992, the Missouri Attorney General obtained a consent injunction and penalties totaling $20,000 against a New York company that sold "aerobic glasses." These glasses, which sold for $19.95 plus postage and handling, had black plastic lenses with tiny holes. The company's ads had claimed that its "Aerobic Training Eyeglass System exercises and relaxes the eye muscles through use of scientifically designed and spaced 'pin dot' openings that change the way light enters the eye." The company had also advertised that continued wear and exercises should enable eyeglass wearers to change to weaker prescription lenses and reduce the need for bifocals or trifocals.

 

        Glare protection for eyes dates back to prehistoric time. Some devices were made of bone, wood or hide, and had slits in them to protect the eyes from the glare of the sun, snow or sea water. These were tied round the head with strips of hide. Today a scientific version of the glare interceptor, called by the distributor Stenopeic (multiple-pinhole) spectacles in which 7 rows of pin-holes of specific size and spacings are placed in a plastic opaque material are available. These, after much experiment, were found to be valuable in certain cases of subnormal vision.
        A few examples follow of the conditions in which they have been used successfully.

Pinholes can be used to improve the vision of people who have had damaging corneal surgery such as LASIK and are bothered by halos and "starbursts" around lights. By creating a smaller pupil, pinholes can reduce these disturbing problems.

People old enough to need reading glasses often can't use cheap, off-the-rack reading glasses due to their astigmatism, which is not corrected by such glasses. Using ordinary pinhole glasses is one obvious solution. An alternative is to wear Snap-Ons over the reading glasses to reduce the astigmatism. Both of these alternatives are cheaper than buying prescription reading glasses with an astigmatic correction. The above also applies when a significant difference in the refraction of the two eyes prevents using off-the-rack reading glasses.

Some people who suffer from macular degeneration have experienced an improvement in their vision when using pinholes

 

Complicated Cases
        Recently a case was brought to my attention. It involved a young serviceman whose eyes had been injured by sulfur dioxide gas. Both corneas had been transplanted and his vision, uncorrectable with glasses, was 20/400 in each eye -which meant he was nearly blind.
        After studying the case I recommended he be given stenopeic spectacles. With these, vision was improved to 20/70 and he could read 9-point type.
        A 70 year old stockbroker had a mature cataract in his left eye and nuclear sclerosis with a small cupuliform opacity in his right crystalline lens. Stenopeic spectacles, by removing the disturbing veiling glare, gave him 20/30 distant vision and permitted 4-point type to be read without difficulty.

Other Complicated Cases
        A recent case was most unusual. A 47-year old man had been disturbed for the past two years by seeing distant objects doubled through his only good eye. The other was amblyopic and markedly divergent. He consulted a qualified ophthalmologist who was puzzled and referred the patient to me. On refracting his seeing eye, I found he had excellent correctable vision, but even with correction he still noted a doubling of the hands on the large clock across the street and the red dots below the numbers on the dial. With stenopeic spectacles he was delighted to see everything sharp and with no doubling.

 

AMAZING EFFECT EXPERIENCED BY THE WEARERS

IN THE FIRST PLACE
        You will see objects clearly through the pinholes drilled in the lenses. Even those who have near-sightedness, farisightedness, astigmatism, or amblyopia can see objects clearly through the small holes. In this case, the eyeball muscles of the wearer get normalized by themselves and the focus of the eyeball(the crystalline lens) is adjusted. The pinholes are small plain holes.

AFTER A SHORT PERIOD
        If you look at things without the glasses after wearing them for about half an hour, you will be surprised that you can clearly recognize even very small letters. (However, you will be soon again unable to see distinctly).

AFTER A SHORT TIME
        If you persist in wearing these glasses only a couple of hours a day while reading books or newspapers, or watching TV, and your eye problems are not hereditary, you will succeed in your sight-recovering exercise, and the eyeball muscles and cystalline lenses will be normalized.(You may not need glasses at all)

REMARKS OF AMERICAN DOCTORS ON THE INVENTION

  1. Dr. Janet Goodrich(a distinguished eye-sight-correcting specialist)
    "People with both close and distant blur and astigmatism are able to use micohole sight correctors."
  2. Dr. David Michael(author of Visual Optics and Refraction)
    "Microholes reduce aberrations and light scattering, isolate a favorable area of the damaged cornea and increase depth of focus."
  3. Dr. Norman Bies(author of Correction of Subnormal Vision)
    "The longer depth of focus obtained through microholes is well established --- patients enjoy a substantial increase in reading distance."
