Review on Revant Polarized Replacement Lenses Stealth Men's Accessories ... Sunglasses & Eyewear Accessories by John Taylor

I bought these as a cheaper replacement for Oakley lenses in my M frames. As the 3 star rating would suggest they are fine. They fit and stay within the frame. I had no problems with that. Sometimes when I look at auto glass I get a weird psychedelic look, a multifaceted look. I think it might be because they are polarized. Otherwise they work as advertised. I hit my head on a pipe about 68 inches off the ground right at eye level and they saved me from abrasions to my face or damage to my eyes. The lens is clearly scratched, but fortunately on the edge and not too annoying.
