Good lenses. Cut out exactly. Fits in the frame very easily. However, since these lenses are slightly thinner than the original lenses, they fall out of the frame more easily than the original lenses. However, the lenses have sharp edges. I feel like they could almost slit my cheek. Well, not really, but it just seems that way to me because they're a bit spicy. 4 stars. Update: I wore these lenses for mountain biking about 2-3 times a week. After having it for over a year, the trim code started to "disappear", there are lines on the shiny reflection code that I can't see. I'm not sure if sweat has anything to do with it. So the price is quite reasonable. But don't expect them to last forever. Much luck!
