Spots before the eyes (floaters)

Small black dots or threads apparently floating before the eyes when looking at a light-coloured surface. They are experienced by almost everybody, although some people are more conscious of it than others and the condition, which is in fact harmless, can be very irksome to them. The floating spots are caused by cloudy points or particles in the vireous humour between the lens and the retina of the eye; its composition gradually changes with age, and cloudy patches – which are normally not noticed – may occur. No treatment is necessary.
