Hi Tom,
When I was young I was sick a lot, measles, mumps, scarlet fever... etc. And each time I was sick my eyes hurt in the light.

Okay, so since then I've discovered that if my eyes hurt in the light and I take vitamin A, I should do that now, actually, it stops hurting. And, I don't squint in the sun as much, either.

I get the cheap vitamin A since it works fine.

You might try that.

Good luck.
