Well my sunglass situation went something like this. When I first started riding I didn’t wear sun-glasses. Then one day while going down a hill a bug flew into my eye and I almost crashed. So I started wearing home-depot safety glasses. Then the safety glasses would start to fog up during the summer and it became tedious to have to wipe them off so often . They also got scratched very easily and offered no glare protection. Then I tried regular sun glasses and they would fog up just like the home depot glasses and they were too dark. Now I wear Oakleys with transition lenses which don’t fog up have sun and debris protection and are not too dark like many cheaper sun glasses I had. They actually darken when it very bright outside and lighten when it gets dark. I’m very happy with them. Though sun-glasses can be costly, its my experience you get what you pay for.
