short-sightedness

for adults and children
The
fit of your Trayner pinhole glasses can be adjusted at the bridge or on
the arms after warming them in hot water. With regular use your eyes
will become accustomed to the glasses; the pinholes may seem to
disappear and any initial multiple images will also diminish.

When
do I use the glasses?
Wear
Trayner glasses during your usual daily activities - no specific
exercises are required.
To
improve your near vision use them for close work such as reading (with
increased lighting if necessary).
To
improve your distant focusing use Trayner pinholes for viewing in the
distance such as watching television and relaxing out of doors.
Trayner
pinhole glasses can be worn to prevent eyestrain from prolonged focusing
at a fixed distance such as working at a VDU or drawing board.
Some
aching of the eye muscles may be experienced after initial use; this is
quite normal but you may wish to reduce your exercise period for a few
days. If desired, the time spent wearing the glasses may be increased to
an hour or more daily as comfort allows.
Trayner
pinholes may also be used as sunglasses which have the added advantage
of letting through the wavelengths of light essential for proper
functioning of the thymus gland. These wavelengths are blocked by
conventional glasses/sunglasses, possibly weakening immune function.
Since Trayner glasses reduce the overall amount of light getting to the
eyes, they also cut down the amount of harmful ultraviolet wavelengths
reaching the eyes. In situations where a high ultraviolet exposure is
likely, e.g. at high altitude, conventional sunglasses should be used.

Frequently
asked questions
Q.
If I wear my strong glasses after using my Trayner glasses won't I undo
the benefits?
A.
Trayner glasses are not meant to be a complete alternative to
conventional glasses. Eye exercise, like any other exercise does not
need to be continued all day to obtain the benefits.
Q.
Can I stop wearing my Trayner glasses when my eyesight has improved?
A.
As with any exercise system, the benefits wear off if you stop
exercising. Once your eyes are fit, however, less frequent exercise with
Trayner glasses will maintain them.
Q.
Will I have to keep on getting my prescription changed as my eyesight
improves?
A.
Trayner glasses help to build up flexibility in the eyes. This will not
itself require a change in prescription. If you would like to change to
a weaker prescription to help your eyes improve further, the flexibility
gained with your Trayner glasses will allow you to do so comfortably.
Q.
Can Trayner glasses damage my eyes?
A.
The Trayner glasses are not forcing your eyes to do anything. They
simply make it easier for the brain to decide how to focus the eye. The
worst you can do is to make your eyes tired with too much exercise. This
is just a sign that you are trying to do too much too soon.

How
do they work?
Difficulty
in focusing results in the image formed in the eye being in front of the
retina (shortsightedness) or behind the retina (long-sightedness). Thus
each point of the image blurs to a circle (i.e. the blur circle). The
greater the error in focusing, the larger the blur circle.
Conventionally an external compensating lens is used to bring the image
into the plane of the retina to give clear vision. This practice
encourages laziness in the eye muscles and commonly stronger and
stronger lenses are required to maintain vision.
The
effect of introducing an array of pinholes in front of the eye is to
reduce the effective aperture of the eye (from that defined by the iris
to that defined by the size of the pinhole in front of the eye). This
reduced the size of the blur circle proportionately (this is the same as
increasing the depth of focus of a camera by 'stopping down' the lens or
reducing the aperture). The reduced blur circle enables the brain to
recognise what to do to focus the eye to give a sharp image, thereby
re-learning how to focus at that distance. The result, with regular
practice, is improved brain-eye coordination and increased flexibility
of the eye focusing mechanisms.
The
fact that Trayner glasses make focusing easier can be usefully employed
to reducing eyestrain in the normally sighted individual. Trayner
glasses are found to considerably reduce eyestrain and headaches in
people who do a lot of close work or spend prolonged periods in front of
VDU screens, whether or not they have recognised eye focusing problems.
The glasses can be worn for unlimited periods by people with normal
vision. It is advised that people who have poor focusing ability and
wish to wear Trayner glasses for long periods, only do so after
gradually extending the period of use, since their eyes would otherwise
be receiving unaccustomed exercise.

Eye
nutrition
A
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, unsalted nuts and seeds, and keep
coffee and refined sugars to an absolute minimum.
Vitamin
A is helpful for many types of eye problems including poor vision in dim
light or at night. Good food sources are: fish liver oil, liver,
carrots, egg, cheese, butter, milk, green vegetables, yellow and orange
fruits and vegetables.
B
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, wholegrain cereals. Some of these products are
a problem for people with candida or wheat intolerance, in which case
use a good quality B complex vitamin supplement.
Vitamin
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
and green vegetables.
Vitamin
E is need to prevent cataracts. It helps to keep the blood vessels and
retina healthy. Good food sources are: wheatgerm, cold pressed olive
oil, wholegrain bread and cereals, green vegetables, unsalted nuts and
seeds.
Bilberry,
the European version of the blueberry, has been called the vision herb
for its powerful effect on all types of visual disorders. Research has
shown that bilberry can improve night vision, relieve visual fatigue,
and help protect the eyes from glaucoma, cataracts and macular
degeneration. Bilberry strengthens the capillaries that deliver oxygen
and nutrients to the eyes; feeds eye muscles and nerves, and works as an
antioxidant to inhibit damage by free radicals. Food source: bilberries,
blueberries.
Lutein
and zeaxanthin were identified in 1995 as the only two carotenoid
antioxidants specific to lens and macula health. Lutein and zeaxanthin
filter light and serve as potent free radical scavengers, and slow down
the degeneration of the macula. Food sources are fruits and vegetables,
but to get enough a nutritional supplement is often recommended.
Selenium
helps to prevent cataracts and to slow the ageing of the eye. Good food
sources are: fish and shellfish, sesame and sunflower seeds, brazil nuts
and wholegrain cereals.
Zinc
is required in a high concentration by 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.
