Hi everyone, I have a pair of wire frame (I guess it's wire frame, as opposed to plastic) eyeglasses and when I was cleaning them one day, the left nose piece, protector fell out, and I can't find it anywhere. Does anyone know if these are replaceable. I don't want spend money on a new pair of glasses. If I go to an optometrist like a Lenscrafters, can I buy a new one? It's become somewhat painful on the old nose. I've had this pair forever, and I'd like to keep them a bit longer, lol. Thanks in advance, Larry
