Eye floaters look like black or gray specks, strings or cobwebs that drift about when you move your eyes and appear to dart away when you try to look at them directly.
Most eye floaters are harmless and don't require treatment. If you notice a sudden increase in the number of floaters — especially if they're accompanied by flashes of light or peripheral vision loss — seek immediate medical attention. This might signal a retinal tear or retinal detachment.
