AGING EYES LINKED TO HEALTH WOES:

The gradual yellowing of the lens and the narrowing of the pupil that occur with age disturb the body’s circadian rhythm, contributing to a range of health problems, these studies suggest. As the eyes age, less and less sunlight gets through the lens to reach key cells in the retina that regulate the body’s circadian rhythm, its internal clock.

So if you’re older, it’s even more important to get out in the bright sunlight. And drink a glass of red wine while you’re there. You don’t want to take any chances.
