These glasses have a defect. The sliver tab in between the arm and the lens frame falls out. I had this happen on two pairs. The first time I figured it was just a one off and purchased again but with the second pair I realized it was a faulty design. I made the second pair into prescription sunglasses had my eyeglass place try to glue them back but both sides eventually fell off and got lost. I reached out to the seller and was told out of warranty. I can understand that but this is a faulty design. Disappointed they are not interested in standing by their product. I asked for replacement parts or a new pair and was denied. Can't just send me a couple of tabs so I can repair them? I put prescription lenses in them so I am out a large cost.
