Old age eye sight can be improve and restore in a painless simple way: Claims Australian researchers

After crossing forty most of us who never had to pay any attention for eyes started experiencing different eye problems.

Old age really brings along many problems regarding vision and eye sight. Apart from common ailment of eye sights like Blurry vision, cataract and glaucoma, old age also bring about dreaded eye diseases like age-related macular degeneration (AMD – the most common cause of blindness in old age), age-related degeneration of the retina and retinitis pigmentosa which causes permanent blindness.

Researchers at the Vision Centre, Australia claims that for the first time ever it is possible to improve or prevent vision loss in old age by using a combination of pain less therapies.

These therapies include light management, anti-oxidant dietary supplements, healing of damaged eye cells using near-infra-red light and short-term oxygen therapy, and are all based on a deepening understanding of the cellular and genetic processes within the eye.

Light management:
When an eye cell has been damaged by overexposure to light it usually dies from stress caused by free radicals – but when the cells are stimulated with near-infra-red light, they appear to recover significantly and to withstand future damage much better restricting the amount of light entering the eye.

Some forms of retinal degeneration, vision cells are particularly sensitive to light and become stressed or die from normally non-damaging intensity of light. Researchers have shown that protecting these retinas from light from birth can slow the degeneration. Even it is found that it is worth limiting light exposure later in life if the eyes were unprotected during childhood.

Anti-oxidant dietary supplements:
Professor Silvia Bisti of the University of L’Aquila in Italy has discovered that a dietary supplement of the herb saffron offers potentially major benefits for protecting and repairing damaged vision. Saffron appears to work not only as an anti-oxidant but also to regulate genes in the vision cells of the eye which can improve their resilience and possibly slow down diseases such as retinititis pigmentosa and age-related macular degeneration (AMD).

Oxygen Therapy:
While oxidative damage is a major cause of the loss of our aged vision cells, it has been observed that saturating the eyes with oxygen for a very short time in a hyperbaric chamber can cause vision to improve,.

According to the report of Vision Center, the  recent research results in animal models show these therapies offer great promise for treating vision loss in conditions such as age-related macular degeneration (AMD – the most common cause of blindness in old age), age-related degeneration of the retina and retinitis pigmentosa which is capable of causing permanent blindness in much younger people. Though it is very early in the research but researchers believe that they will be able to know more positive results later this year.
