f. Does it really work if you use lux?

pu1. From what I've used, I think my eyes are less tired at night when I use flux

OK

pu2. Blue light blocking film is only 30% blocked even if it's expensive, so the effect is very good. I think it would be better to adjust the flux and remove the blue light

OK

pu3. For phones, use anti-fingerprint (anti-glare) films rather than blue light blocking films. The anti-fingerprint film has the lowest light reflection, so the clarity of the handwriting is a little low, but the glare really goes away
