Eye (Visual) Floaters

Medically reviewed by Last updated on Feb 4, 2024.

What are eye floaters?

Eye floaters are specks or spots in your vision. They are dark and may look like squiggly lines, cobwebs, or strings. These spots or specks move around in your field of vision. The floaters seem to drift or dart away if you try to look straight at them. Eye floaters are also called visual floaters.

What causes eye floaters?

Floaters may be caused by tiny particles of debris or blood that float in the vitreous. The vitreous is the gel that fills most of your eye. As you age, the vitreous shrinks and pulls away from the retina. The retina is the thin layer that lines the back of your eye. When this happens, the tissue becomes stringy and casts a shadow on the retina. These shadows can cause you to see floaters. Floaters may also be caused by problems with the retina.
