What are floaters?
Floaters are clumps and strands in the vitreous, the gel-like material, inside the eye. You can see floaters as black spots or shadows which move around as you move your eyes. They are formed as a result of an ageing process of the vitreous.
Most of the floaters are not a problem but they can be a sign of a serious condition such as the retinal detachment. Therefore, if you experience a sudden increase in new floaters, flashing lights and/or a growing shadow (curtain), you should see an ophthalmologist urgently.
