Floaters are small pieces of debris that float in the eyeâs vitreous humour. Vitreous humour is a clear, jelly-like substance that fills the space in the middle of the eyeball. The debris casts shadows on to the retina (the light-sensitive tissue that lines the back of the eye). If you have floaters, it is these shadows you will see. Floaters can occur as your eyes change with age.
