I purchased eyeglasses here only to have the non-reflective finish get mottled after a year on ONE lens only! I telephoned them about the problem and was told that their service warranty is good for only 30 days after purchase!!!! These were expensive progressive bifocals with "PearleThin" lenses and cost me almost $500. A complete waste of my money, and they showed me how little they really care about their customer's eyesight AFTER they have sold them their eyeglasses!
