React Optray

Our sunglasses fit securely, weigh almost nothing, and adapt to light in less than a second. They are so good that you'll completely forget you're wearing them. Thanks to our light-adaptive technology, our lenses seamlessly transition between medium, dark, and very dark tints. Our lenses are powered by integrated solar cells and mounted in a lightweight frame. Both our lenses and frames are the result of Swiss precision manufacturing and quality control.

With our ShadeTronic technology, our lenses detect changes in ambient light and adjust accordingly in less than one-tenth of a second. You won't even notice it – you have other things on your mind.

Our lenses darken 300 times faster than conventional photochromic lenses and lighten 1200 times faster, so you'll never lose focus. Since our lenses automatically switch between medium, dark, and very dark tints, you never have to change your sunglasses or lenses on the go.

Our polarized lenses with UV400 rating protect your eyes from harmful UV rays, allowing you to see clearly and safely at all times. Integrated solar cells power the liquid crystals in our lenses, ensuring they brighten and darken in response to changing light conditions in just one-tenth of a second. No charging is required, as there is no battery.
