Fashionable and versatile blue blockers for nighttime use.

Our wide acetate Cleaver frames with our orange Nighttime lens make the perfect combination for comfortable evening wear to block blue and green light.


Cleaver Frames

Slash through blue light with our Cleaver frames. These frames offer wide coverage with our fashionable style. With a glossy black exterior and translucent red inner accent these frames are great for both casual and office environments.

Despite its size our Cleaver frames use specially formed ultra-thin acetate to keep it lightweight and balanced. Acetate frames are widely regarded as the highest grade plastic for glasses as they are adjustable, hypoallergenic, and long-lasting.

Reverse spring hinges allow the frames to flex to nearly any head shape, and the acetate temples can be additionally molded to perfect comfort.

Orange Lens

Our Orange lenses are specially formulated to reduce 94%+ of blue light 380nm-500nm and 40% of green light up to 560nm. This ensures you get optimal functionality with maximum protection.

These are designed for people who want to be active and productive in the evenings. We want to wear our nighttime glasses without stumbling around, turning up brightness on devices, or looking over our glasses.

  • Evening and Nighttime wear for blue and green blocking
  • Enjoyable social usage with less stumbling around or loss of alertness
