Floaters are very common.

They are tiny cells which 'float' around in the jelly in the eye.

They appear as small black dots or strings ...

... particularly when looking at light-coloured objects.

Sometimes the number of Floaters can increase dramatically.

It may also be accompanied by flashing lights.

If vision is significantly impaired ...

... the jelly inside the eye can be removed ...

... and replaced with an artificial substance.

Alternatively, a laser can be used to destroy the Floaters.
