Eye Floaters: Causes, Risks & When to See a Doctor

The vast majority of eye floaters are not dangerous and do not require treatment. They are caused by small clumps of cells or protein fibers in the vitreous, the gel-like substance that fills the inside of the eye. Floaters can appear as small dots, lines, or cobwebs, and they can move around when you move your eyes.

Although most floaters are harmless, some can be a sign of a more serious eye condition, such as a retinal tear or retinal detachment. If you experience a sudden increase in the number of floaters in your vision, or if you see flashes of light or a dark curtain moving across your field of vision, it is important to see an eye doctor right away.

There is no treatment for most floaters, but if the floaters severely interfere with your vision, your doctor may recommend a procedure called a vitrectomy, which involves removing the vitreous and replacing it with a saline solution.

Here are some things you can do to help reduce the appearance of floaters:

• Drink plenty of water to stay hydrated.

• Get regular exercise.

• Avoid activities that put a lot of strain on your eyes, such as reading in dim light or staring at a computer screen for long periods of time.

• Eat a healthy diet that includes plenty of fruits and vegetables.

If you are concerned about the floaters in your eyes, it is important to see an eye doctor for an evaluation.
