At first I was skeptical about wearing sunglasses with violet lenses, however grew to really enjoy the reflective qualities of violet lenses. As far as the construction, it is enjoyably simple – only 3 pieces. Two plastic stems that snap onto the frame. No need to worry about screws or braces bending or breaking. If the stems break off on these Frogskins glasses I simply just snap them back onto the frame. eBay is listing these glasses for $64.99 w/ fast 'n free.
