I have a pair of Randolph Ranger XLW glasses for shooting. I use the lightest yellow as my all around lens, but I'm looking at the two darkest lenses for general non shooting sunglasses use. They are the copper polarized and the CMT lenses. I have a fairly dark copper tinted clip on for my regular prescription glasses and and pretty happy with how well they work in bright sunlight. I have no experience with the CMT lenses. Does anyone use either or both of these lenses, and can you compare and contrast the performance of each type? Thanks.
