Worst purchase ever from Amazon! Inferior quality - it's like a piece of wire.    I must say I regret posting the negative comments on this frame a month ago.. I am not use to seeing glasses frames so thin and did not read the description properly. My husband decided to see how flexible they were so he tested by bending back and forth. Honestly we thought it would break in pieces but they stood the test. He will be taking them to the optician to have them fitted with prescription lenses.
