I purchased a pair of Caribbean sun glasses from Walmart in Paola, Ks in Febuary of this year, my ear piece came off on after having them for a couple of weeks i personally put the screw back in after that the screw came out in the other earpiece i took them into the vision center at Walmart the women could not get the screw back in she then took the glasses to the back put the screw in and i was on my way. I got into my car and put the glasses on only to notice marks on the inside of both lens. I went back into the store to complain she told me it was from the ear pieces rubbing the lens. I then ask what could be done she said there was nothing she could do, the glasses i paid for cost over 70.00 dollars and when we bought them we were told that they were garunteed the same as the prescription ones we purchased on the same day! Why would i pay that kind of money for sunglasses that didn't have anymore warrenty than a ten dollar pair. Walmart is not worth there word and these Caribbean sunglasses are a piece of crap
