455 nm is Where it Matters Indoors.

Blue light comparisons must be made at 455 nm. Digital devices and LED lights emit blue light from about 430 nm to 500 nm with an intense spike at ~ 455 nm. Do not be tricked by other “wannabe” blue light “blocking” lenses that only provide blocking percentages in the part of the spectrum where digital devices emit little to no blue light, making their protection insignificant.
