Transitions® photochromic lenses have the leading light-adaptive technology. Your eyes are always exposed to the optimum amount of light, whether you’re in bright sunlight, under a cloudy sky, or indoors. Transitions® lenses provide 100% UV protection for all lens colours. Stop switiching between regular glasses and sunglasses. Theese lenses automatically transition from clear to the right level of tint when activated. Transitions® lenses can be used with any prescription and on single vision or progressive lenses.
