Ray Ban 4261D Black injected blue lenses Definitely uni-sex for men or women! *plastic frame *plastic lens *non-polarized *Lens width: 55 millimeters *Arm: 145 millimeters Mirror lenses act like a one-way mirror. They are made of a lens covered by mirror coating of a given color...these being blue. The mirror coating decreases the amount of light passing through these lenses making them ideal for sunny days. I do not see any scratches on these at all. Barely worn. Last pic is the same style
