According to research, two-thirds of all Americans will have a cataract by age eighty-five. There is growing evidence that vitamin E may help to prevent this most base age-related vision problem. A cataract is a cloudy or opaque exterior that grows over the lens of the eye, which can cause total or partial blindness. A cataract can distort vision by development objects look vague and fuzzy. If the cloudiness on the eye lens becomes so severe it hampers vision, the cataract must be surgically removed. Four million U.S. Men and women have cataracts, and most population who have them are over the age of sixty. Cataracts are so lowly in the United States that more than 10 percent of the Medicare allocation is spent on cataract surgery.
In rare cases, a cataract may be caused by a genetic problem, but the spectacular, majority of cases are caused by cellular damage to the eye lens inflicted by exposure to ultraviolet and illustrated light. The lens of the eye is particularly susceptible to light-induced lipid and protein oxidation, a major factor in the majority of cases of cataracts. The lens contains proteins called crystallins, which, when damaged, can come to be irregular and refract light in the wrong way, thereby foremost to cataract formation.
Vitamine
There are some reasons why I am optimistic that vitamin E may prove to be a useful tool in the stoppage of cataracts of the eye. First, numerous animal studies have shown that vitamin E can arrest and reverse the improvement of cataracts symptoms and can protect the sensitive lens tissue from oxidative damage. Second, population studies have documented that population with low blood levels of antioxidants E, C, and carotenoids are more likely to create cataracts than those with higher levels. The third, and maybe the most persuasive, bit of evidence is a new study that easily contrasted the self-reported consumption of supplements by 175 cataract-free patients over fifty-five to that of 175 patients of the same age group with cataracts. The cataract-free group used significantly more vitamins C and E than the group that already had developed cataracts. I think it is fair to say that even if vitamin E does not do the job alone, in compound with other network antioxidants it may offer marvelous safety against cataracts of the eye.
