These lenses are light as a feather with a minimalist design. The last thing you need is to add more weight and bulk to your glasses.

Tested to block 100% of light from 280 – 490nm (this includes UV). Blocks 99.8% of light in the critical 450 – 510nm range. This is the most disruptive wavelength of light at night.
