+1 on Sports Optical. They made my wife's and mine. She couldn't get anyone else to make a pair due to her strong prescription but Sports Optical has some proprietary method for doing this. Sports Optical did a fantastic job on both pairs. Highly recommended. I got the new Transistions lenses that are photochromic , I really like them because I can walk indoors and not have to change to another pair.
