Why we're blind to the color blue

I think that the title is a massive oversimplification because chromatic aberration by itself is not enough for us to be blind to the color blue. We do have cones that can detect blue for one.

We are however, less sensitive to it so maybe the eye doesn't focus based on that channel(?).

I wanna point out that LCA cannot be responsible for e.g. blue displays being basically impossible to read. Why? Because they are still impossible to read when they're the only thing that's around, and blue LEDs are very monochromatic. So the eye would have to focus on the blue light, which would make LCA go away.

I suspect that a plausible cause could be that there just aren't a lot of blue receptors in the retina, as the eye is pretty insensitive to blue overall.
