Nutrition affects all aspects of our health and the eyes are no exception. Eyecare practitioners tend to focus solely on the ocular structure but might forget that the eyes are a direct connection to the brain and central nervous system. Myopia was once considered a benign refractive condition with an inherited link, and wearing glasses to compensate for visual clarity was the only option for patients. Changes in the structure and function of the eye can be attributed to nutritional as well as lifestyle factors. This course will review some nutrition basics and review the science of how these nutrients can affect the onset and progression of myopia.
