From what I've written, f.When I use lux, my eyes seem to be less tired at night.
Blue light blocking film is only 30% blocked even if it is expensive, so the effect is not that good.
I think it would be better to remove the blue light by adjusting it at f.lux.
For phones, use anti-fingerprint (anti-glare) films rather than blue light protective films.
The anti-fingerprint film has the lowest light reflection, so the clarity of the handwriting is a little bit less, but the glare really goes away.
