Floaters and Flashes

What are Floaters?

Floaters are tiny spots, threads or fragments drifting in your field of vision. They’re made of cellular material and float in the thick fluid that fills your eye. Most are caused by age-related changes that develop as the fluid becomes more liquid. Other causes are inflammation in the back of the eye, bleeding in the eye or a torn retina. Risk factors are nearsightedness, aging, eye trauma, complications from cataract surgery and diabetic eye disease.

What are Flashes?

Flashes, which look like lightning streaks or flashing lights, occur when the fluid rubs against the retina. They may be a sign of disease, retinal detachment, head trauma or chemical exposure.
