My eyewear for Skeet & Trap is a set of Wiley X PT-1's with replaceable polycarbonate inserts in lots of different shades (gray, rust, rose, amber et al).  I found a second pair on ebay clear, gray & rust inserts and bought them for my truck.  I haven't had a problem with scratches, but mine go into a case when not being used.
