I have purchased two different pairs of progressive prescription lenses from Tajima Direct. Both went into Costa's frames and to be honest, the clarity was better than the ones provided by Costa. I have been so impressed with the quality of the lenses and AWESOME customer service (none better anywhere), I actually took a big gamble and ordered replacement progressive prescription lenses (Gray 15 non-mirrored) for my wife’s favorite pair of Ray-Ban frames for Christmas. They arrived a couple of days before Christmas and the prescription was spot on. Now these are my wife’s favorite sunglasses. We’ll never buy another pair of lenses from anyone else. Thanks
