Isn't blue light really bad for eyes

  No, it's not.

    Yes it is. It can damage retinal cells. But this isn't deep blue and not very bright. https://health.ucdavis.edu/blog/cultivating-health/blue-light-effects-on-your-eyes-sleep-and-health/2022/08 https://health.ucdavis.edu/blog/cultivating-health/blue-ligh...

      There's research showing that extended exposure to (extremely bright) sunlight can damage the eyes. There's no research I'm aware of showing that blue spectrum light from, eg., a computer or cellphone screen, which is what people are usually concerned with, can do damage. (And obviously nothing about blue lights on cars, but clearly they're not going to be particularly bright either.)
