Floaters and Flashes
The College of Optometrists have developed this leaflet to help you understand more about floaters and flashes.
Floaters look like small dark spots or strands that appear to float in front of your eyes. Floaters are very common and are normally harmless. They are more common if you are short sighted or as you get older. Some people also notice they see flashes of light. These can be due to movement of the gel inside the eye. Very occasionally, flashes or an increase in floaters can be a sign of a retinal detachment, which needs treating as soon as possible.
