How old are you, Ken? I started noticing that I had to peer over the
tops of my glasses to focus on close up, tiny things about two years
ago. My older students laugh at me, it seems I have passed a middle
aged milestone in their eyes and am now an equal.  :--) I am 43, and
changes in eyesight are common at this age. I don't know how diet
affects this, if it does.

I recall working with poor peasant families, and how wonderful their
eyesight was, even old people could see much better than me at a
distance. Their diets are very poor, mostly corn and beans, with
occasional veggies and fruits and meat as a treat. But their eyes were
great. No TV, no computers, not much reading and writing. I think a big
part of eye health is tied to how we use them. They also were outdoors
most of the time, in full tropical sunlight, maybe that played a part.
They sometimes asked me why all Gringos had such bad eyes, they thought
it was a racial thing.
