Eye floaters are spots in your vision. They may look to you 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 caused by age-related changes that occur as the jelly-like substance (vitreous) inside your eyes becomes more liquid. Microscopic fibers within the vitreous tend to clump and can cast tiny shadows on your retina, which appear to you as floaters.
Symptoms of eye floaters may include Spots in your vision that appear as dark specks or knobby, transparent strings of floating material. Spots that move when you move your eyes, so when you try to look at them, they move quickly out of your visual field. Benign eye floaters almost never require medical treatment. If eye floaters are so dense and numerous that they affect your vision, your eye doctor may consider a surgical procedure called a vitrectomy.
Floaters have been reported in patients as young as 9.They may be of embryonic origin or acquired due to degenerative changes of the vitreous humour or retina. However, floaters in teenage patients and young adults are usually harder to treat.
