i broke two almost immediately by dropping them from a height of less than 3 feet (they fell off a tv tray).the part that holds the lens is very thin and brittle. i was very careful from that point onward, but just had one of the two remaining break *while wearing them*.i was reading and the part of the frame holding the lens just broke with a noticeable sound. it seems to me the lenses are held with too much tension in the frame. other than that they're great.
i was happy at first knowing that i can see up close. but after a few days, i now see imperfections on the lens which causes fuzziness and blur when watching tv or using my desktop computer. out of the five pairs received, two are okay but the other three glasses are useless. i am watching tv and realize i see better once i remove the glasses. i should have paid more to get better quality. too bad i discovered this after my return period expired.
