CloseHPSx—Sunglasses by day, grow glass by night. The Coup HPSx is the world’s first and only photochromic grow glasses. 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 very dark grey/blue tint when exposed to direct sunlight. Set in the fashion-forward Italian-made Coup frame. Transition experience varies based on conditions and UV exposure. HPSx lens is made in the USA. Microfiber pouch included for proper cleaning and storage. 100% UV protection.
