The Method Seven Evolution HPSx Transition is the perfect solution for indoor growers who need to transition to outdoor activities without changing their eyewear. These lenses are made from a durable polymer that utilizes photochromic technology to change from blue color balancing under high pressure sodium (HPS) grow lights to soft grey/blue in direct sunlight. With these lenses, you can experience natural color, comfort, and protection both inside and outside. The transition time varies based on weather conditions and UV levels, but it generally takes less than three minutes of consistent exposure to direct sunlight for the lenses to change over. HPS Transition lenses offer 100% UV protection and crisp contrast, and they are made in the USA. The frame of the Evolution HPSx Transition is made in Italy with a fashion-forward design that features concealed flex hinges for a custom fit that doesn't skimp on style. The Evolution frame is comfortable and flexible, made with TR90: an incredibly durable and lightweight thermoplastic material that allows the frame to bend under pressure and contour your face.Product not normally stocked within the store please allow up to 1 week for delivery.
