If I had 20/20 vision, my favorite cycling glasses would be the $30 no-name made-in-China glasses that I picked up from some equally no-name vendor's booth at the Death Ride several years ago. They fit great, have great coverage, are very lightweight, have acceptably uniform optics, and make me look like a boss.

Sadly, I do not have 20/20 vision, and so I can only wear those $30 glasses when I'm also wearing my contact lenses...which means I can't go on a long ride (because my tolerance for contacts is limited to about three hours) and I can't go on unfamiliar routes (because my contacts don't compensate for presbiosis so I can't read a cue sheet while wearing them).

So my $30 no-name glasses rarely get worn, and instead I usually wear my $600 custom-ground Rudy Project Ketyums made by Brett at SportOptics. Yes, you read that right: $600

And I would do it again in a heartbeat. Best money I ever spent for a cycling accessory. (Actually, I am going to do it again in a heartbeat, because I need a clear or amber version for night rides.)
