what causes black floaters in eyes


Eye floaters are caused by age-related changes in the vitreous, the jelly-like substance inside the eyes, which liquifies and contracts. This causes scattered clumps of collagen fibers to form, which cast shadows on the retina and are seen as floaters. Floaters can also be caused by the natural shrinking of the vitreous as you age, which can cause both floaters and flashes of light. 1 2 3

Summary Floaters usually happen because of normal changes in your eyes. As you age, tiny strands of your vitreous (the gel-like fluid that fills your eye) stick together and cast shadows on your retina (the light-sensitive layer of tissue at the back of the eye). Those shadows appear as floaters.

Summary Eye floaters are tiny specks or strings that float into the field of vision, usually caused by age-related changes to the eye. They are usually harmless, but can impair vision if the underlying condition worsens, and can be treated by rolling the eyes from side to side and up and down to move the debris. If the floaters become too bothersome or numerous, a doctor may recommend medical attention.
