    I'm blind in my left eye due to RD. But if I close my eyes or if I'm in a
    dark area, I see millions of dimly flickering dots. I'm curious about what
    they are.

    Normally, the photoreceptor nerve cells of the retina change the light rays
    into electrical impulses and send them through the optic nerve to the brain
    where an image is perceived. But any stray electrical impulses in the optic
    nerve or in the area of the brain that processes vision, may also cause
    images to be perceived by the brain.

    The fact that the images you see are "dimly flickering dots" is not
    surprising, sort of like a really bad TV signal connection that only
    contains random noise, and not a clear image on the TV set.
