Method Seven Coup HPSx Transition

Sunglasses by day, greenhouse glasses by night. The HPSx lens is a proprietary polycarbonate blend that allows the lens to transition from the direct blue of our HPS color balance technology to a dark gray/blue tint when exposed to direct sunlight. The transition is activated by direct sunlight and completely darkens within three minutes. Experience balanced colors and protect your eyes for hours of comfort and enjoyment, wherever the day takes you. Italian coupe frame with concealed flex hinges. The HPSx lenses are made in the USA. Includes a microfiber pouch for proper cleaning and storage.
