I got eye glasses on 5/9/15. Progressive cost 159.99. Frame zyloware 058 cost 59.99. The frame is extremely brittle. It broke in Sept. Associate tells me there is no warranty as we try to keep cost low. You buy similar frame to save glasses. If it brakes again you spare side arm. 9 members of my family buy glasses from Costco for last 10 years. Never had such material. So bought on good faith. $219.98 gone down the drain for good faith.
