Syntonics: Optometric Phototherapy

Screen-Shot-2019-01-14-at-9.30.04-AM.png

Syntonics or optometric phototherapy is a branch of ocular science that deals with selected light frequencies viewed through your eyes. It has been used in optometry for over 70 years to treat a variety of visual dysfunctions. These dysfunctions include strabismus, amblyopia, convergence problems, vision-related learning disorders, and traumatic brain injuries.

Syntonics improves vision problems by balancing the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is stimulated by the yellow, orange and red ends of the spectrum and the parasympathetic is stimulated by blue, indigo and violet end. Green will stimulate both systems equally.

Visual dysfunctions can be related to difficulty in the brain processing what information that the eyes are bringing in. The theory behind Syntonics is that by applying certain frequencies of light through the eyes, one can restore balance within the brain and directly affect the source of certain visual dysfunctions. Vision therapy is often used after the light therapy to strengthen individual visual skills that may be dysfunctional.

Before, during and after syntonic therapy the pupils and functional visual fields are tested, along with symptoms, to determine the effectiveness of therapy. Therapy can be done in the office or with a portable system that is given for home use.
