Clear-lensed TrueDark Daylights lenses filter 40% of wavelengths between 370nm and 500nm. In comparison, our yellow Daylights lenses filter 75% of wavelengths between 370nm and 500nm. Remember that blocking 100% of blue light during the day is not ideal because your eyes do need SOME exposure to blue light order to help you stay awake and alert when you need to be.
TrueDark Twilights glasses block at least 98% of the wavelengths below 590nm – basically all blue, green and violet light. We block the broadest spectrum on the market!
