Pinhole Glasses New Styles
The Downhill Slide.
When your eyes are placed behind normal prescription
glasses you fall into a trap. You no longer use the focusing
muscles in your eyes to the full. This important "ciliary
muscle" begins to weaken requiring visits to your
eye doctor for stronger and stronger lenses. Reverse the
downhill slide and help develop your eye muscles now.
fix that fails kids' eyes

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

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.
|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
advantages that pinholes have over prescription glasses:
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.
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
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
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.
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
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.
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.
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.
do not have to be cleaned of fingerprints and other marks
that affect vision.
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.
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

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.
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.
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
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
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
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.More
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
MORE 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
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)
|Pinhole glasses are suitable
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
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.
