I have a spare pair of Oakley sunglasses at the house with lenses that are scratched. I want to get some polarized replacements because I've recently started fishing but Oakley's are $100 just for the lenses. I found a company called Samvette that makes replacements and they are $25 for polarized lenses. Has anyone used their lenses before? I'm sure they aren't Oakley quality but are they good?
