Sol Optometry


Syntonics, or optometric phototherapy, is the branch of ocular science dealing with the application of selected visible light frequencies through the eyes. It ​has been used clinically for over 70 years in the field of optometry with continued success in the treatment of visual dysfunctions.  These including strabismus (eye turns), amblyopia (lazy eye), focusing and convergence problems, learning disorders, and the aftereffects of stress and trauma. In recent years, Syntonics has been shown to be effective in the treatment of brain injuries and emotional disorders.

Light is essential to life. Our planet revolves around the sun and all life on earth is sustained by sunlight. Different wavelengths of light striking the retina are interpreted as colors by the brain. These different wavelengths are, in essence, a form of energy medicine. Light is energy, and the body needs exposure to a diverse assortment of those energy wavelengths. The Greeks were the first to document the use of phototherapy. Currently, light is used to treat a variety of disorders - from the "bili" lights used on jaundiced newborns to the more recent psychiatric use of while light for treatment of Seasonal Affective Disorder.

Interest in the effect of light on the body intensified earlier this century. Most of the current therapeutic techniques used in Syntonics are based on the work done by Dr. Harry Riley Spitler in the 1920s and 1930s. Dr. Spitler, who had both optometric and medical degrees, began researching and using photo therapy in 1909.  The author of "The Syntonic Principle", he conceived the principles for a new science that he called "Syntonics", from the word syntony (to bring into balance), referring physiologically to a balanced, integrated nervous system. Colored light therapy can act as a powerful tool to stimulate the biochemistry of the brain through the visual system by way of the retinal-hypothalmus brain connection.
