These are pretty sweet all around. They have a removable foam insert that even with RX lenses is nice to wick away sweat and produce a debris free filter. The way this style of glassed is curved takes a while to get used to. The focal points seem more clear than the peripheal fields. After a week or so though your eyes get used to it. I can switch from my RX casual frames to these and have no problem. Awesome buy, durable, attractive. I'd suggest calling in your order, staff is very helpful and intelligent.
Pros: Cheap
Cons: Convex takes some getting used to.
