Eye floaters are small moving spots that appear in your field of vision. They may be especially noticeable when you look at something bright, such as white paper or a blue sky.
Eye floaters can be annoying, but they generally don't interfere with your sight.
Occasionally a particularly large eye floater may cast a subtle shadow over your vision. But this tends to occur only in certain types of light.
Most of the time people learn to live with eye floaters and ignore them. And they often improve over months to years. Only rarely do benign eye floaters become bothersome enough to consider treatment.
But sometimes eye floaters are a sign of a more serious condition. You should seek immediate medical attention if you notice a sudden increase in the number of eye floaters.
