I'm 'assuming' there is a certain wavelength they are referring to, and not just "any blue light"...
As an aside, I bought light-blockers (sticky black shapes) on amazon to put over the led lights on the stove, microwave, refrigerator, etc. to make my sleep 'deeper'/more black (at night).

LOL.
I had some red plastic which was sold to stick to, and patch, busted tail lights. Put small pieces over the annoying blue lights on the monitor, old desktop and shredder, and it helps.
I’ll have to stop in the auto parts store and see if they still sell it.
