I bought these for my boyfriend, he has a pair of radar oakleys and was needing new lenses. We did not want to be out 100+ dollars just on lenses so we settled for these. If your used to oakley lenses, you can definately tell the difference in quality. I would not recommend this product unless you want to settle for a lower grade quality lense. They are not as clear as the oakley lenses and they are already starting to scratch, with minimal everyday wear.
