I dipped my toe into the "online glasses" market -- and let me say it's a game-changer. The eyeglass store wanted about $300 per frame, meaning that I'd grudgingly get one pair.

The online purchase was only $75 for high-end frames and coatings, plus $27 for three pairs of prescription "computer monitor" glasses (one for the office, one for the home office, one for the other home office!). And by having more pairs, I can bring a pair on trips, just in case the main ones get broken!

(Personally, I've also never had any useful help in picking out frames. I'm not very fashion conscious, and every time the help doesn't seem to want to actually help be find frames that would look good on my face)
