Anyone got a suggestion for a decent (low eyestrain) set of polarized polycarb lens sunglasses? I typically buy glass lens Smiths when I find them on sale or ebay for a good price. Glass lenses have always seemed clearer and and felt like they gave less eyestrain. But now that my fishing time is limited by the "kid schedule", and I find myself trying to stretch the daylight hours, I think I'd like to try out a pair of low light yellow lenses. However, I don't think I'm ready to drop real coin on them. Chili's from REI? Whatever "super-fishing" glasses it is that WalMart carries? Something else? Spend a little more and get an interchangeable lens set? Save my cash for something else and get cheap-o safety glasses from the hardware store? Thoughts?
