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. back to headings 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. back to headings 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. back to headings 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. back to headings 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. Top of page The
