Cataract and Macular Degeneration

Several studies have shown Vitamin E to be protective. One of them was reported by Dr James M. Robertson of the University of Western Ontario in London, Ontario.

He examined the relationship of supplements and cataract formation in 350 men and women. He divided them into 2 groups. One group of 275 cataracts, and the other did not have cataracts,

“The consumption of supplementary Vitamin C and E may reduce the risk of senile cataracts by about 50 – 70%,” says Dr Robertson.

Dr Paul F. Jacques of Brigham and Women’s Hospital published a study involving 112 patients: 77 with cataracts and 35 without cataracts. They did dietary analysis and also measured the plasma levels of Beta-Carotene.

They found those with low plasma levels of Beta-Carotene had 5 times the risk of developing cataracts compared with those who had high Beta-Carotene levels.

Vitamin C is concentrated in the eye lens at a level 30 – 50 times greater than that of the blood.

Obviously Vitamin C is extremely important to the lens of the eye? Why? Because it helps protect us from cataracts.

A group of Australian researchers gave one group of people Vitamin C and E for 5 years and gave another group a placebo. The group not on the vitamins had 80% more cataracts! Remember the antioxidants often work as a team.

According to the studies by several leading eye specialists, there is ample evidence that damage to the lens involves oxidation due to exposure to ultraviolet rays, enviromental airborne pollutants and other oxidants.

This has been the vitamin most mentioned in preventing cataracts, although Vitamin E, Beta-Carotene and the mineral Zinc also appear in the literature.
