Latest Cataract Research – Vitamin E, Selenium May Not Prevent Cataracts

Cataract is the leading cause of blindness in the world. It is estimated that it was the cause of blindness of 20 million people worldwide in the year 1998. Night driving becomes even more strenuous and natural light causes major vision difficulties. Besides the fact that the eye becomes sensitive to flashes, it may also result with severe headaches. Occurrence of double images can create confusion and the feeling of disorientation as well as some problems with distinguishing colors.

The latest research

A new study indicates that vitamin E and Selenium don’t have preventive effects on men. Surveys conducted in previous years indicate that both of these substances have preventive properties. But according to latest Mayo Clinic research Selenium and vitamin E have only placebo effects on patients that consume them regularly. This research involved more than 10000 people that were asked to report for cataract examinations if they notice anything wrong with their vision.
The research lasted for about six years and 413 cases of potential cataracts emerged during that time. They found 195 cataract cases that used selenium which is close to 203 other cases that didn’t consume this supplement. On the other hand, 218 cases that were taking vitamin E also resemble the number of patients that didn’t consume this supplement in that same period. This can only indicate that the use of vitamin E and selenium doesn’t have impact on the manifestation of cataract.
