I found this post using Google to search for the reason that I sometimes see white dots when I open my eyes while still in deep sleep.
I have studied the human eye in my psychology classes, so my speculation is that when we sleep the Ganglion cells, or the related rods and cones that collect the images that we see, shut down during sleep. This is the main reason that we sleep: to give these types of cells the time to take a break and repair themselves.
I suspect that the white dots are the cells being out of commission and transmitting no information to our brain receptors, resulting in white spots.
I am searching for more information since my speculation fails to answer why the rest of my visual field is not missing. Again, I suspect that certain cells are slower to respond to stimuli when I open my eyes.
