Scientific research shows that most eye problems can already be apparent in adolescence but become more clearer as the body grows older. Often they develop slowly over the years, long before the first symptoms become noticeable. It is important to take preventative measures as early as possible.

Our eyes are subject to many external influences. Artificial light, working with the computer screen, unfiltered sunlight, smoke, wind, pollen, dust and free radicals all tax our visual ability. That is why a diet containing substances which provide preventative action for our eyes is very important. The eye of the older person in particular needs special dietary supplements, vitamins, trace elements and anti-oxidising substances. It has been shown that luteine is very important for the prevention of what is known as the degeneration of macula lutea as a consequence of growing older. The macula lutea, also known as the yellow patch, enables the eye to read, recognise small details and distinguish colours. In the macula lutea luteine carotinoid is found in its highest concentration. This has the function in the eye of filtering dangerous rays such as bright sunlight. In addition it is an anti-oxidant substance that can make safe dangerous free radicals formed by ultra-violet rays. The body cannot by itself make luteine and thus it must be ingested as part of our diet.

The positive effect of bilberries on sight are known of old. Extract of bilberry and the anthocyanes it contains can help to improve the micro circulation in the retina. They stabilise the fine capillary vessels of the eyes and so improve the supply of nutritive elements and oxygen, which enables the eyes to better resist the daily load. In addition the anthocyanes have an anti-oxidant effect. Again, many age-related eye problems can be traced back to insufficient supply of nutritive substances and oxygen in the capillary blood vessels of the eye.

Beta carotine, also known as pro-vitamin A, is turned into vitamin A inside our body. Vitamin A is important to our vision, especially at night. When there is a deficiency of vitamin A, the eyes have difficulty in adapting to night vision. Vitamin A deficiency can also lead to other changes and complaints in our eyes. Thus there is a strong suspicion that a vitamin A deficiency may lead to the development of cataracts and the age related degeneration of the macula lutea. Recent studies have shown that the trace element zinc works together with vitamin A and thus enhances the beneficient work of vitamin A on vision even further.

Selenium and vitamin E also supply the increased demand for anti-oxidant substances required when the eyes are heavily used.

Vitamin B12 supports the energy catabolism and has a positive influence on the visual nerves.

It is important to point out that even with children protective measures such as the use of sun glasses must be taken. That applies also to adults, since it is now known that even in European latitudes the intensity of ultra violet rays has increased of recent years.
