Most medical types agree that the sensor input into the brain's balancing operation are:

Eyes
Visual Information(40%)



Ears
Vestibular and Auditory Information(30%)



Articulations
Proprioceptive Information(30%)

When the "ears" are screwed up---the brain balancing operation counts on the "visual" input to a larger extent for balance info.....which is why with an ear problem if you close your eyes---you lose your balance......if you take a look at how BLIND people deal with "no vision" vis-a-vis their balance---it helps you to understand---how important vision is to balance....

..."Balance
Vision is neurologically linked to the body's balancing system. There are direct brain connections between the vestibular (balancing) system of the inner ear and the vision system. In some disease states, when the middle ear is destroyed, the only sense that can keep victims upright is vision. If the eyes are closed, the affected individual falls down. The loss of vision is the loss of a powerful balancing system; blind children may be less stable than their sighted peers, especially when blindness is congenital, and especially during early stages of development."....
