Ocushield glasses are AMAZING! They are the most lightweight, adorable frames -- I actually buy additional pairs to use the frames for prescription lenses. Also, their customer support is absolutely terrific. When I accidentally listed my previous address on the order after having just moved, I reached out asking for a return label that I could use to faciliate the return of those glasses (and then re-order them to my new home). They immediately sent an entire new order to my new home and said there was no need to faciliate the return of the ones sent to my previous address. An outstanding product and outstanding customer service!
