I have good vision: no known issues, regular eye checkups, etc. But I find it nearly impossible to read most displays that use blue LEDs. If the background is blue (eg: timex indiglo watch) then it's fine. But blue leds on some of my home theater equipment drive me insane. Even if it isn't the letters/numbers themselves and it's just a regular circular power led, I find them really hard to look at.
- originalbryan2 6y agoI first noticed the blue light issue when xmas led lights were put on trees around the holidays. Blue blurry things. Now my credit union has their sign in blue and I can’t read it. 10 years later I developed astigmatism in both eyes. Dark mode is really blurry in some settings. The blue light thing, as I understand it, is where you first begin to notice astigmatism. The wavelength is shorter and a very slight astigmatism becomes more apparent.
