  • SUPERIOR BLUE BLOCKING - The same best selling Spectra479 lenses can now be used with prescription and reading glasses
  • LIGHT WEIGHT - 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
  • BRIGHT & CLEAR LENSES - These are designed to pass as much non-blue light through as possible. There is no dark tint and they are not polarized. You can still make eye contact with loved ones and even forget you are wearing them.
  • TECHNICAL SPECS - FDA approved 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. It is also the same frequency of light that is blasted directly into your eyeballs from electronic devices! Always wear protection!
