Light Therapy and Vision By Dr. Robert Fox, OD, FCOVD, FCSO

One of the subjects I am asked most about in the course of treating our patients is Light Therapy, also known as Syntonics. In our practice we frequently send our patients home with light units prior to the start of their in-office optometric vision therapy. The results are often very dramatic.

Briefly, light therapy has been used to treat vision and other health issues since with 1930’s. Optometric participation dates back to 1941 when H. Riley Spitler, a physician and optometrist published “The Syntonics Principle.” Though its popularity has varied during the years, it is now experiencing tremendous growth in vision therapy circles with this year’s meeting in June in Pittsburgh selling out its introductory courses.

Syntony means “to bring into balance.” In syntonics we use specific frequencies (colors) of light, shined into the eyes to produce changes in the nervous system. For example, if a child has an eye that turns inward, a specific red light would stimulate an outward movement of the eyes, helping us to better treat this condition. The other benefit of syntonics is enlargement of one’s peripheral vision. In a school child, a tunneled field of vision can often cause reading problems, loss of place, poor spacing when writing, and general clumsiness. Enlarging this child’s field can greatly enhance their school and sports performance.

Though originally in the realm of alternative medicine, syntonics is rapidly moving into the mainstream of developmental vision care. In fact, a recent article on the Mercola health information website featured syntonics and can be found at:
