Magster Outlet Replacement Lenses
My originally purchased Magster frame and lenses wore out; found a killer deal on a replacement frame/lens combo package, so I bought that. After one particularly hard bike ride I fainted and hit the deck; my lenses were scratched pretty badly, so I purchased the latest replacement lenses (Photo clear to black); I do not think they are polarized, but that's ok. They do transition from clear to dark fairly quickly, so I'm happy that I now will not have to use my clear lenses for night rides (I may still do, though). About the only thing I do not like is that the Magster seems to not be in production any more, which means I will eventually have to buy a different frame (a Rydon, perhaps?)
The Rudy Project lenses are tough, with good clarity/definition, and (when you get buy them via the Outlet) a bargain price-wise.
