I was amazed how easily they toss over my glasses. It feels like your glasses aren't even part of the equation, I've yet to have my glasses tilt or get caught or get bumped at all. In today's world of big goofy plastic aviators, these actually look pretty sleek and normal. Not a head turner either way, good or bad. Which is what I wanted.

Effective at a good price. I will say they are slightly bothersome after many hours of wear, but I don't think that could be avoided for under $20
