They're the best bifocal sunglasses I've ever seen and I love them for glancing down at my cycle computer or changing a flat. ONO makes prescription versions of their glasses, too.
Thanks for the info on these. I'm still deciding whether to give up contacts or not. Maybe I should be switching contact lens brands to something that doesn't dry out my eyes so much. I have an eye exam coming up, so i'll ask a lot of questions before deciding.
