Why do People Notice Eye Floaters

We don't actually notice the eye floaters themselves, but rather the shadow they cast into the retina.

You might be wondering why you see floaters when looking against a light background, yet not a darker one. The reason is simple: As a background is more lighter colored, the floater's shadow becomes more apparent to the brain.

In case you're wondering, part of the reason floaters are not seen in darker places is because the brain has actually learned to ignore them. They are there.

A common sensation many floater sufferers have is that of being watched. As you have eye floaters moving around your vitreous, you might think seeing someone "out of the corner of your eye". However, if there's no one there it's probably just a floater.

To see what eye floaters actually look like visit the Images or the eye diagram.

Floater in eyesight?Well, it serttad out as just a dot in my right eye. I never really did notice it much. Its been around for a few years. Now its more than just a dot. it looks more like a big dot with hairs coming out from it , kinda reminds me of a spider lol. Black and cloudy, when I move my eye it moves. Its been like this for a few months now but seems to be getting worse. Its starting to get very annoying! I dont have vision insurance, and Im not due for my exam until Feb anyways. Last time I went I didnt mention the Dot The eye Dr did say that the pressure in my eye was dangerously high but didnt say much more about it. I do wear glasses. I suffer from high blood pressure, Migraines and high blood sugar. Im 20 years old and other wise healthy. My uncle was blind due to his diabetes but other than that I cant think of any more problems in my Family.Could this floater be serious or is it normal to have these?

This is very interesting. So how big are the actual eye floaters?
