Glasses - How they Work
glasses provide an infinite depth of focus when the eye is not correctly focused,
the object will appear as if in focus. They eliminate scattering of the light
to the retina and hence help to improve vision.
glasses are designed to improve eye problems, especially eye focussing problems.
looking through any pinhole blurred images become focussed. This is because the
amount of peripheral light rays is reduced. With appropriately spaced multiple
pinholes you will get clear straight vision without the difficulty of concentrating
on a single hole. Regular use of the pinhole glasses helps exercise eye muscles
and helps the eye to relax.
Wearing Pinhole Glasses while watching TV or reading instantly makes it easier
for your eyes to focus with less strain
glasses - How to use
improve short sightedness (myopia) or blurry vision, use pinhole glasses for viewing
sports, television, VDU or just looking around relaxing, for 30 minutes a day
improve long sightedness (presbyopia), use pinhole glasses for reading or close-up
work. Make sure you have enough lighting from behind you.

Pinhole Glasses - The Benefits
glasses improve vision clarity & resolution. Vision improvement is guaranteed
- it is a scientific fact! Increases object brightness - ideal if you struggle
with vision in low-light situations. Good vision at all distances
Glasses - The Science
ancient Chinese discovered that light passing through a tiny pinhole makes an
image on the background it falls upon. Aristotle (384-322 BC), the great Greek
philosopher, expanded on this, laying down the principle of pinhole imagery.
first known application of pinholes came over 1,000 years later when Alhazen
(Ibn Al-Haytham), used the principle to invent the pinhole camera - a light tight
box through which a pinhole on the front surface of the box allows direct light
rays to enter and form an image on the back of the box. The idea of capturing
an image drove inventors and scholars in Renaissance Europe to explore the science
of pinholes further, discovering that light moved in straight lines, unless refracted
by a lens or some media that acted like a lens.
eventually led to the invention of the Camera Obscura capturing a large
image through a small lens.
have been used to aid vision for hundreds of years. There is evidence that Eskimo
communities have used fabrics and wood with narrow slits in as a primitive form
of pinhole glasses, in order to protect their eyes from the glare of the sun off
the snow and ice for many centuries. In the mid 20th Century, pinhole glasses
for public use were pioneered. Although the first prototypes of pinhole glasses
were unattractive, heavy and cumbersome to use, technological advances in materials,
lasers and production methods have meant that the pinhole glasses of today are
high-tech in comparison.
medical profession too have adopted the science of pinholes as a way to measure
visual acuity and to detect refractive vision disorders in their patients.
often use a pinhole occluderto gauge visual acuity on a 20/20 or 20/50 scale,
and also to determine the extent of a patient's refractive error (measured in
diopters). This device is essentially a pinhole which is held very close to the
patient's eye, and works on the principle that anything seen through a tiny hole
will always be seen in focus. If the patient can see a target image through the
pinhole more clearly than without the pinhole, then traditionally ophthalmologists
prescribe eye glasses (logically, the ophthalmologist should prescribe pinhole
glasses as he/she has just proved that pinholes do improve vision!)

with 5 minutes a day; later you may wish to increase to 5 minutes twice a day.
These exercises are best done without glasses or contact lenses.
- Cup your hands and place them gently over your closed eyes. Total darkness is
very therapeutic and relaxing for the eyes. Palming may be done at any time during
the day to revive tired eyes. Whilst palming your eyes perform the following exercise:
Keeping your head still, look down as far as you can, then return your eyes to
the centre. Continue by looking to the right as far as possible, up as high as
you can and then to the left, returning the eyes to the centre after each movement.
Repeat this 10 times.
- Focus on an object, e.g. a pen tip, held at arm's length. Slowly (take at least
5 seconds) bring it in until it touches your nose, focusing on it all the time.
Move in and out 10 times.
3. This is similar
to exercise 1. This time focus on a pen or other object held in your hand. Hold
this directly in front of you and move it slowly as far down as you can continue
to see it. Focus on it all the time, wiggle it if necessary to help you see it.
Repeat for the other directions, focusing on the object on the outward movement
only. Repeat 10 times.
healthy well-balanced diet is of great importance if you wish to maintain or improve
your vision. Base your diet on wholefoods, eating plenty of fresh fruit, vegetables,
nuts and dairy products and keep tea, coffee and refined sugars to an absolute
minimum. You will then be well on your way to improving not only your vision,
but your health in general as well. Certain vitamins and minerals are of particular
importance to your eyes:-
A is helpful for many types of eye problem including poor vision in dim light
or at night. Good food sources are: fish liver oil, liver, carrots, egg, cheese,
butter, margarine, milk, green vegetables, yellow and orange fruits and vegetables.
complex is required by the eyes to keep them healthy. A deficiency of B2 can
lead to bloodshot, burning or gritty feeling eyes, cataracts and sensitivity to
bright lights. Good food sources are, brewer's yeast, yeast extract, wheatgerm,
C has been found to be helpful in the prevention of cataracts and glaucoma.
High concentrations of vitamin C are found in healthy eyes. Good food sources
are: citrus fruits, other fruits including tomatoes, green vegetables, potatoes.
E is needed to prevent cataracts. It helps to keep the blood vessels and retina
healthy. Good food sources are: wheatgerm, vegetable oils, wholegrain bread and
cereals, green vegetables.
helps to prevent cataracts and to slow the ageing of the eye. Good food sources
are: fish and shellfish, sesame and sunflower seeds, wholegrain cereals.
is required in a high concentration for the retina to function properly. Zinc
is also required to release vitamin A from the liver for use by the eyes. Good
food sources are: shellfish, liver, red meats, eggs, sardines, nuts and seeds.
Make sure to give your eyes time to adjust to the pinhole effect of these glasses.
It may be distracting at first, but after a few minutes the brain disregards the
holes and gives you clear vision. Blink your eyes more often then you would do
Glasses should not be used while you are driving, involved in sporting activities
or operating any machinery.
