>I couldn't read the oven clock (blue on black) at just 10 feet away
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.
I 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.
