Perceived as black dots or grayish lines appearing in your field of vision.

Vitreous floaters are quite common in people over 50. They occur when the vitreous humour detaches from the retina, and they appear as small specks, strands or cobwebs that float in front of the eyes. They are not painful and in most cases are harmless, but they can become very annoying, because they follow the eye’s movement, floating in and out of the field of vision and disrupting both eyesight and concentration.
