Is it my eyes aging? (My acuity of vision is still as good as it ever was, though I realize that might not be measuring the same thing.) Is it that I live in a more northerly attitude so the sun is lower in the sky? Is it the thinning of the ozone layer and other environmental depredations making sunlight more intense? Did I always need sunglasses and just didn't know it, or got used to it?

I only need them if I'm driving on a particularly bright day or if there's a lot of snow glare. I find it annoying to wear sunglasses; I feel a little cut off from what's going on around me.
