In the simplest terms, eye tracking is the measurement of eye activity. Where do we look? What do we ignore? When do we blink? Balance is achieved and maintained by a complex set of systems that include nerve input from the eyes (sight).
Most people don’t find it difficult to walk across a gravel path, or to transition from sidewalk to grass, or getting out of bed at night without stumbling. However, eye problems can lead to impaired balance. Symptoms of impaired balance can be quite unpleasant and include dizziness and vertigo.
When light hits the eyes, they send nerve impulses to the brain that provide visual cues identifying how a person is oriented relative to other objects. Exercising the eyes, is as important to preventing current or future balance problems as is exercising the body.
