What are moving white dots in your eye that when you look at them they move with your eye?

have noticed swarms of light dots moving quickly and erratically in my eyes. I notice it most often when I am looking at the sky or my blank blue computer screen. It scared me until I found out what causes it. The scientific name for this perception is Scheerer's Phenomenon. Far from being a disease condition it is actually evidence of excellent blood circulation in the eye. Here is what happens. Our blood has small opaque red cells and much larger clear white blood cells that move in the tangle of capillaries that are over the surface of our light sensitive retinas. Our eyes ignore the tiny shadows that would be caused by the red cells but they are just able to sense the light passing through the larger clear blood cells. As a result, we see what appears to be a thousands of tiny lights or sparks moving erratically in our visual field. Most people totally ignore this but if asked to concentrate on a blue field like the sky or a computer screen, they will see it too. It might be that people with perfect 20/20 vision are more likely to see them than people who focus a more blurry near sighted image. So rejoice if you have this "condition" your eyes are probably in very good shape!
