How much blue light do your glasses block?

Our glasses have been lab tested for transmittance % of blue light at nanometer wavelength intervals from 780nm-290nm. 

Our glasses block virtually 100% of the harmful part of the spectrum from 290nm to 415nm (UVA and UVB). This part of the spectrum is also invisible to human sight.

From there blocking gradually tapers off into the visual spectrum to 70% at 420nm, 50% at 425nm, 35% at 430nm and so on. 

How much "Blue Light" do they block? Roughly 50% if you take into account the transmittance % at each nanometer interval. 

This is the industry standard for clear blue light-blocking lenses. But most importantly, they block virtually 100% of macular degeneration-related light. 

If you are looking for glasses that block 100% of visible blue light, then we would suggest looking for yellow-tinted or red lens blue light glasses.
