Why we filter blue light
Blue light is high-energy light that screens emit, and it may have negative impacts on our health. Studies show overexposure to Blue Light may be linked to eye strain, increased risk of macular degeneration, and sleep cycle disruption. Our lenses filter blue light, particularly the highest energy wavelengths of 400-440 nm.
Why we eliminate glare
Glare creates unnecessary feedback that our eyes need to filter out. This may impact our visibility and create stress on our eyes. All our lenses feature a premium AR coating (anti-reflective) that blocks 99% of glare. Now you can leave that glaring problem in the dust for good.
