I have Flak Draft Asia fit with Prizm Daily Polarized (non-prescription). I like to fly fish and am considering getting prescription Prizm Shallow Water Polarized. I've used the Prizm Daily while fly fishing, skiing and driving and they seem to work just fine but I'm wearing contacts and then have to use reading glasses when tying knots, untangling line, reading, etc. which is less than ideal. Anyone one have experience with the Prizm Daily vs Prizm Shallow Water lenses for fly fishing? If getting a prescription lens I'd probably use it while driving, biking (road and mtn) and skiing. Ideally, I'd like one prescription lens that will work well in all situations, especially fly fishing and skiing. Also, any recommendations on retailers to cut the prescription lenses? Thanks!
