Have you ever experienced floaters? Floaters are tiny floating shapes that appear in the human field of vision from time to time. If you’ve ever seen a clear floating strand of hair or an odd floating circle in the corner of your eye, you’ve experienced floaters.
This phenomenon, scientifically called muscae volitantes, happens when proteins, red blood cells, and tissues cast shadows upon your retina. This video from TED-Ed breaks down exactly what happens with floaters, including explaining exactly how they appear in your field of vision.
Have you ever seen a floater? What did you think it was when you first saw it?
