Taking daily supplements of selenium or vitamin E appears
to have no significant effect on the development of cataracts
in men. The results of an American study involving 11,267
participants, followed over a period of 5.6 years, shows that
long-term use of daily vitamin E supplements has no effect on
cataract incidence. The data also exclude any large beneficial
effect on cataract for long-term use of selenium supplements,
with or without vitamin E, although a smaller but potentially
important beneficial effect could not be ruled out.
