I think it's because you aren't moving your eyes. Your eyes usually move around slightly so some nerves can rest and/or your brain can construct the image. But I could be wrong. I'll ask my magic 8 ball.

It's called the Troxler effect or Troxler fading or Selective Peripheral Fading.

I couldn't find much on it quickly.

Actually, there is no green spot, just blank gray.

That is true.

Also, try hyperphysics for "rods and cones".

If you move your eyes in a circle following the dots, you cannot see the "green" dot, they all remain "pink" (they look closer to pink than purple)
