Do floaters lead to blindness?

A fellow caregiver asked...

Is there a way to prevent floaters? Will they go away? Or will blindness be the final outcome?

Expert Answer

Lylas Mogk, M.D. is an ophthalmologist and director of the Henry Ford Visual Rehabilitation and Research Center in Grosse Pointe and Livonia, Michigan, and the author of Macular Degeneration: The Complete Guide to Saving and Maximizing Your Sight.

There is no way to prevent floaters and they won't go away; however, most people become less aware of them as time goes on. They are just little condensations in the gel that fills the hollow inside of your eyeball. They do not cause vision loss and they certainly do not cause blindness. The final outcome of floaters is that you just get used to them and consider them entertainment when you're daydreaming.

If, in addition to floaters, you have flashes of light, eye pain, a decrease in vision or if you suddenly see a huge number of floaters when the day before you only saw one or two, then see your ophthalmologist because those additional symptoms might suggest something more than just floaters.
