Description Method Seven Coup HPS Transition are sunglasses by day, grow glasses by light. Adjust from signature blue color balancing technology under HPS grow lights to soft grey/blue in direct sunlight.

Crafted from a durable polymer, these proprietary lenses use photochromic technology to transition from signature blue color balancing technology under high pressure sodium (HPS) grow lights to soft grey/blue in direct sunlight. Experience natural color, comfort, and protection wherever the day takes you. 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.

Frame Technology Fashion-forward, chic, and Italian-made, the Method Seven Coup HPS Transition saunters from the grow room to the city street without batting an eye. This fashion-forward wayfarer features concealed flex hinges for a custom fit that doesn’t sacrifice style. The frame is comfortable and flexible as it’s made with TR90: an incredibly durable and lightweight thermoplastic material. Produced with Swiss technology, TR90 allows the Coup to bend under pressure and contour your face. Why Method Seven? Grow rooms have lots of light, but it’s not broad-spectrum. Though this might be great for plants, it’s not so great for your eyes. Human eyes contain rods and cones, which need broad-spectrum light in order to perform their functions. These functions include things like focus, recognise shapes, register movement, and see colour. In a grow room environment, sunglasses make things worse by darkening all the light. You might squint less, but you still can’t see colour, and it’s even more difficult to focus. Other grow light glasses attempt to colour balance the extreme light spectrum but use cheap plastic lenses. The cheap plastic lenses usually have very poor clarity that distort light and are hazy or blurry. Method seven delivers epic colour and complete safety under HID lights. You’ll see foliage accurately, spot pests and deficiencies early and efficiently. No headaches, strain, and no long-term eye damage. Don’t Grow Blind.   Frame Dimensions Coup frames also available in Method Seven Coup Sun Polarised.
