Undulating like strands of kelp drifting on a minuscule ocean, “eye floaters” can be annoying. Sooner or later 70 percent or so of us will endure eye floaters or their pesky cousins, eye flashes.
Although a variety of medical conditions can cause floaters and flashes, the most common culprits are iffy connections between the back of the eye and the vitreous, the eye’s Jell-O-like core.
Sometimes — especially as we age and our vitreous thins — little patches of the wobbly thing can pull free from the back of the eye. As the vitreous yanks on the touchy retina nerves, sparks fly and flashes appear. And sometimes strings of vitreous cells are torn free. These cells bobbing about in the vitreous cast shadows on the retina, which we see as floaters. The sudden appearance of bursts of flashes or large floaters can indicate serious medical conditions, such as a detaching retina, and warrant a trip to an ophthalmologist.

How Many Megapixels Does The Human Eye Have?
If the human eye was measured in megapixels. like camera’s are, how many would it have?
You see things one way, and your camera sees things differently.
So, what is the resolution of the human eye, at which a camera would be able to truly capture an image the way the eye sees it?
The answer is 576MP, the technical breakdown is as follows:
Consider a view in front of you that is 90 degrees by 90 degrees, like looking through an open window at a scene. The number of pixels would be 90 degrees * 60 arc-minutes/degree * 1/0.3 * 90 * 60 * 1/0.3 = 324,000,000 pixels (324 megapixels).
At any one moment, you actually do not perceive that many pixels, but your eye moves around the scene to see all the detail you want. But the human eye really sees a larger field of view, close to 180 degrees. Let’s be conservative and use 120 degrees for the field of view.
Then we would see 120 * 120 * 60 * 60 / (0.3 * 0.3) = 576 megapixels.
The full angle of human vision would require even more megapixels. This kind of image detail requires A large format camera to record.
Therefore, once our cameras reach 576MP, the pictures you take with your camera will look exactly the same as you see them.
