Like what others have said.
It’s placebo.

It doesn’t help “reduces eye strain” in any meaningful way.

Furthermore, if it does filter out “blue light”. Most of what you see will be more greenish/yellowish/reddish.

But hey, if looking at things which are warmer calms you down, go for it. That’s why some people prefer yellow warm lighting at home rather than bright white light.
