Flashes and Floaters

Alternate Names : Vitreous Opacities, Spots in Front of the Eye, Light Flashes

What can be done to prevent the condition?

Most cases of floaters and flashes of light cannot be prevented. They are a common and almost normal part of aging.

What are the long-term effects of the condition?

Floaters and flashes of light themselves cause no long-term effects. Flashes of light usually go away within a few weeks. Floaters can sometimes be noticed for years, but the brain usually learns to ignore the floaters and they become much less noticeable with time. An examination is important, however, to rule out other more serious causes.

For example, if undetected, a tear in the retina can sometimes lead to permanent loss of vision. Fluid can leak through the hole and accumulate under the retina, causing the retina to detach. When this happens, surgery is needed to correct the problem. However, if a retinal tear is found early, it can be sealed using a laser. This reduces the risk of detachment.

What are the risks to others?

This condition is not contagious and poses no risk to others.
