Does blue light from digital devices speed blindness?

Scary. Incompetent Ginvasso said studied show computers do not harm our eyes. I thought bull they cause headaches and I strain. I read studying saying computers cause eye strain, This sounds worse.

That sounds a little scary, but it also sounds like they can fairly easily correct the problem using blue light filters.
I think I mentioned before that I never liked "black Lights" (ultraviolet lights). The lights they used to make posters glow, especially back in the 60s. I could feel the light on my skin and eyes.
Maybe my body was trying to warn me.

I'm sure the same problem exists with PC monitors. Just like with TVs.

My iPad filters blue light. They say using it before bed will not keep you awake. What about computers?
