I wear prescription aviator sun glasses when it is bright. Cloudy days or evening riding I just wear my glasses. I am going to get me some transition lense glasses because I am tired of having to change from glasses to sun glasses and then try to remember where I left the other pair. I plan on getting the PRK done rather than lasik. I don't like the idea of the lens on the eye having a possiblity of falling out after lasik I know the odds are extremely slim but the possibility is there.
