Are they like little black or white blotches floating around when you lie down or jerk your head? If they are then it is perfectly normal, your retina gets rid of dead cells like skin does so it creates an illusion when the cells float over your pupil it looks as if it is some weird object when it in actually on your eye. Happens some people a lot or it may never happen others.

Your ears are responsible for balance so if your balance is affected too you may want to get your ears checked out by a GP.
