Some glasses have frames made of memory titanium and are literally indestructible. My pair have survived a few years of harsh treatment. I've sat on them twice, gotten hit in the face with a basketball several times, and they still bounce back to their original shape. They weren't cheap (about $350) but they will definitely last until my vision changes enough to need new lenses - which aren't even scratched because of some protective coating. Even so, I often use lenses so I can play lacrosse and also because psychologically it makes me feel better not to wear glasses.

- pbemaddy 17y agoThe psychological benefit of contact lenses is at least as great as the vision aspects. A guy I know ditched his glasses and bad haircut over the summer, and now with blue opaque lenses and Sun-in his whole persona has changed from nerdy to cool!
- scott_s 17y agoMy glasses have the same kinds of frames, and while they're resilient, nothing is literally indestructible. They're still inappropriate for many sports. The value in the frames, to me, is how light they are.
