Floaters
Floaters are small shapes that some people see floating in their field of vision.
Floaters are caused by small pieces of debris that float in the vitreous humour of the eye.
Although floaters are usually harmless and don't significantly affect your vision, you should have your eyes checked by an optician on a regular basis (at least once every two years).
In most cases, floaters don't cause significant problems and don't require treatment. Eye drops or similar types of medication aren't effective and won't make floaters disappear.
