Interchangeable
One difficulty in choosing your winter sports eyewear is which colour lenses to go for. Sunglasses and goggles with interchangeable 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 or for night skiing. Included in this section are convertible products with swappable headstraps and arms, these can be interchanged between goggles and sunglasses for maximum flexibility.
