I was having a cigarette on my back deck and the sun was out. I was looking up into the sky, just watching the smoke rise and not thinking anything particular. While looking up I saw those familiar lil white specks that show up when you let your eyes relax. The ones that swirl around eachother and fly out of your field of vision why you try to focus on any of them.
So my question:
How does this phenomenon occur? Where do these particles, for lack of a better term, originate? Outside my eye, i.e. is light striking them earnestly? Are there small molecules in my eye that are not allowing light to pass through for a brief moment that create these? Are the nerve signals from the eye to the brain missing information somehow that your brain fills in when your not paying attention to it? Is my brain just misfiring?
Your thoughts on what those little specks are.

I've had them for years. As for the blue-white 'sparks', they can be caused by a few things...some harmful, some not and some in between. For me, when I get the 'sparks' I know that a migraine is on its way...
