Floaters. Seeing spots? Learn the causes of eye floaters and the shapes they take.

http://www.macfarlaneoptometrist.com.... Seeing spots like mosquitoes or threads of cotton in your visual fields? You might have vitreous floaters. Just about everybody sees "floaters" especially when looking at a very light or plain background. Floaters are specks or dark areas that the eye "sees" but that are non-existent in the real world the eyes are viewing. The eye is filled with a gel substance (called the vitreous humour) through which light passes to the retina (which is situated at the back of the eye). The retina translates the information received and sends it to the brain. If the vitreous humour contains an opacity, then the light path is interrupted, a shadow is cast over the retina and this is interpreted as a dark speck or floater. http://www.macfarlaneoptometrist.com....
