VISION IMPROVEMENT PINHOLE GLASSES
Discover how to relax
your tired eyes and enjoy reading the healthy
without prescription glasses.
Inexpensive - No Prescription
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 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
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.
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
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.
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
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.
glasses are an excellent substitute for expensive
bifocal glasses. They can provide good vision for
any distance, both far and near.
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
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.
the most important use for pinholes is in an application
that has until now been totally ignored, Myopia
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
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.

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

|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
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.
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
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)
