Oakley lense clarity is awesome. I used to ride with the $20 cheapies for years then I got some Radars and riding was much more fun. They do collect sweat on the bottom where my cheeks will rub against them but I can't see it until I take them off for which I promptly wipe them down, put them back in the bag and case. There are two nicks in them from I guess rocks that flew up but better the glasses than my eyes.
