I can't be the only one with this problem--I'm sure someone has found a good solution and maybe they'll share.
I have Tifosi Pave polarized sunglasses for riding. Any ride over 40 miles and I get a faint fuzzy haze over them, inside and out, but mostly in. It's probably from a combination of my sweat, dust, etc. I ride by the beach a lot so maybe the humidity is a factor also. I have to stop and clean them for about 5 minutes with a silk cloth during my ride. I clean them thoroughly at home afterwards (glasses cleaner).
They are not fogging up, just getting a buildup of dust that obstructs my vision enough to be annoying (and potentially dangerous).
Is there some kind of special coating that you put on them to keep the gunk from building up? I tried something I had lying around the house (303 Aerospace protectant) and that made a small difference. I'm thinking of using some high quality car wax (Zaino, for those who are OCD about cars too).
Is there anything that you guys recommend to resist the gunk/haze that builds up?
