Floater: Usually just a vitreous floater caused by thin strands of connective tissue that run through the vitreous jelly in the back of your eye. Sometimes, however, there can be blood in the eye from diabetic retinopathy or trauma. Go see your specialist eye md (ophthalmologist) who will establish the exact cause.

Get examined: You are describing a floater which is likely nothing but can be caused by problems in the retina of vitreous. You need an exam.
