Floaters
Floaters are shapes which people can see drifting across their vision. The exact form of these is very variable – they may appear as small dots or irregularly shaped strands. Generally people should not be concerned about seeing one or two floaters in their vision, particularly if they have been there for some time. A sudden increase in the number of floaters, especially if you also see white flashing lights, is seen with posterior vitreous detachment. You should contact an eye specialist to see advice.
