I have been wearing reading glasses for about three years - never had any vision problems, except for standard color blindness.
Some days, it seemed, my eyes were better than other days. But recently, while sitting in the open sun waiting for a car repair, I was able to read everything in my wallet, right down to the tiniest print without glasses. So there must be a connection between the amount of light and the ability to focus, but I've never heard of such a thing.
Any comments?
Thanks
Bryan
