Anecdotally, every optometrist and ophthalmologist I met, who wasn't selling me something at the time of conversation, was pretty dismissive of the whole "blue light filtering" business.
The attempt to block blue light has been with us so long (like a decade or so), the blue-light-filtering products so well commercialized, and yet the underlying claim that blue light affects sleep remains to be inconclusive at best, which makes me doubly wary of its validity.
