I have a blue light filter on my glasses since ~3-4 years now, because an optician suggested it last time I fixed my glasses. I can affirm it has absolutely no effect on eye strain. What actually works for me: - be sure to have correct lenses for your glasses, sometime checking with an optician isn't enough and an ophthalmologist (i.e: a doctor) is required - setup good lighting in your office/work area - reduce display backlight during the day, when the daylight reduces - do not set your display in front of a window, try to have it perpendicular instead. The contre-jour effect can be really tiring over time (i.e: when you're facing both the light source of your display and daylight)
