Pros: Comfortable, Durable, Optimal clarity
Cons: sun gets behind lense when overhead

Purchased these glasses four years ago when I started wearing contacts and was amazed at their performance and fit. I have to replace lenses due to the arms hitting the lenses when closed and the rubber grips are splitting. The only bad thing about these glasses is if the Sun is very high overhead it will get behind the lenses and cause lots of glare.
