It is very common to have dizziness triggered by watching things move, as opposed to moving oneself. Many people feel dizzy in busy visual environments, such as browsing in a crowded grocery store, at busy intersections, or even seeing someone carrying a boldly striped bag. This problem, referred to by British researchers as visual vertigo, is caused by your brain not being able to match up the information coming from your eyes, your inner ear and the proprioception sensors on your joints. When you watch a 3-D movie, your eyes follow things around as if you were actually moving. If your brain is hard-wired to believe your eyes more than your inner ear or body, the message from your eyes will dominate and you’ll feel dizzy.
A treatment for visually-stimulated vertigo consists of watching things in motion. Audiologist Erica Zaia suggests repeatedly watching full-screen versions of the NED Leader (right and left) video clips on YouTube. When you get the feeling that you want to look away, watch for three to five seconds longer. Becoming accustomed to doing the tai chi “cloud hands” movement follows the same principle; it habituates your brain to the movement of your hands.
