The floating specks you sometimes see in front of your eyes are not on the surface of your eyes, but inside them. These floaters are bits of cell debris that drift around in the fluid that fills the back of your eye. They may look like spots, specks, bubbles, threads, or clumps. Most adults have at least a few floaters. There are times when they may be more visible than at other times, such as when you are reading.
Most of the time floaters are harmless. However, they can be a symptom of a tear in the retina. (The retina is the layer in the back of the eye.) If you notice a sudden increase in floaters or if you see floaters along with flashes of light in your side vision, this may be a symptom of a retinal tear or detachment. Go to an eye doctor or emergency room if you have these symptoms.
