Sunglass by day, grow glass by night. The HPSx lens is a proprietary polycarbonate blend that allows it to transition from the signature blue of our HPS color-balancing technology to a dark grey/blue tint when exposed to direct sunlight.
Transition is activated by direct sunlight and darkens fully within three minutes. Transition experience varies based on conditions and UV exposure. Experience balanced color and protect your eyes for hours of comfort and enjoyment, wherever the day takes you. Italian-made Coup frame with concealed flex hinges. HPSx lens made in the USA. Microfiber pouch included for proper cleaning and storage.
