What are eye floaters? How do they manifest themselves and how can they be prevented?

They are small spots that can be seen when looking at a smooth, illuminated background like a wall or the sky. They are tiny conglomerates of the jelly-like substance that forms the vitreous humour of the eye. Generally, they are of little importance and are caused by age-related changes although they can be associated with serious diseases, such as uveitis, vitreous haemorrhage or retinal detachment.

They cannot be prevented, but they can help detect other possibly related issues precociously. It is advisable to consult the ophthalmologist if suddenly new floating bodies appear; if you see flashes of light or if you experience a loss of lateral vision.
