Allow me to try and persuade you. The problem is bright blue LEDs. It's still stupid that they make them so bright, but the problem isn't the color. A hypothetical bright red, green, or amber LED would also be a problem.
Shorter wavelengths hit different though. That's why we have blue light filtering glasses, Redshift, etc.
Those glasses are pseudo anyway.
a non-diffused, bright, monocromatic red led would still be painful to look at in the dark, it's just that blue LEDs tend to be brighter + our eyes are more sensitive to blueish green light at night + the damn companies don't bother putting a diffuser in front of the diode.
Diffusion and overall brightness do make a difference as well.
This is fair. I have had to put tape over a red alarm clock because it was too bright before. Those manufacturers also get the oubliette
