I do wear glasses; last April, I discovered Zenni Optical, and picked up a pair of prescription sunglasses that I've been happy with. (I recently found some fashion advice that one's eyes should be roughly centred in one's glasses' lenses. I've preferred aviators for, well, as long as I've been wearing glasses, and am unsure whether this advicoid makes sense or not, but at least I won't bankrupt myself if I try to follow it.)

I have more troubles with the sun than just my eyes; I'm as fair and pale as you're likely to find, and will sunburn at the - pardon me - drop of a hat.
