Need advice for a screen anti blue light filter from a good brand (Solved)

[Logan]

Hello.
I need to get some screen blue light blocker for several devices, but I cannot find any from a reliable brand, I searched some like 3M, Zeiss, etc, but found nothing.
The devices screen size varying from 2-8 inches, bigger filter size is Okay because I can cut them by myself.
I’ll accept those optical films not designed for screen(need to stick them by my self), I just don’t want to buy from those random brands that no one knows.
Thanks.

Assuming the devices can't be redshifted in software, have you considered something like a Rosco Cinegel 3408? That'll give a colour temperature of about 3800 K, at a transparency of 73%. There is a redder option, the Cinegel 3411, which would give about 3200 K but you're down to 58% transparency at that point.
