Red, I wore my first bifocals in jr. high and the only issue I remember was walking up and down stairs but I got used to it after a couple weeks.

I had lasik surgery 5 years ago (one of the best things I've ever done) and my reading vision deteriorated quickly afterward. I wear cheaters on the end of my nose like Oak does and even keep a pair in my bike bag. There's no way I could change a tire without my reading glasses.
