Interchangeable

One difficulty in choosing your sports eyewear is which colour lenses to go for. Interchangeable sunglasses with multiple lenses can solve this problem very cost effectively. Most include three lens sets - grey smoke lenses for bright sunny days, yellow lenses improve both contrast and depth perception on flat light days and clear lenses may be needed in very dull conditions. Some even include 5 lens sets with extra clear mirrored and driving lenses.
