Taking vitamins E and C may do nothing to protect aging eyes from macular degeneration -- the leading cause of vision loss in older adults, a new clinical trial finds.
Researchers had been hoping the vitamins, both antioxidants, could shield against the tissue erosion that occurs in macular degeneration. The condition involves damage to the center of the retina, which makes it hard to see fine details.
Studies have found that people who get more antioxidants in their diet have a lower risk of macular degeneration. But that doesn't rule out other possible diet or lifestyle explanations behind the link.
And so far, clinical trials using vitamin E have come up empty.
