What Is Syntonic Optometry Therapy?

Syntonic Optometry Therapy is a form of light therapy used by behavioural optometrists to address visual problems. Syntonic therapy is a non-invasive procedure where a person looks at a light source through a coloured filter. This coloured filter is prescribed to patients based on visual measurements.

How does Syntonic Optometry Therapy work?

Syntonic therapy (light therapy) uses visible light frequencies (colour), through the eyes, to enhance visual attention and decrease the symptoms of stress. When light enters the eye, the brain is able to perceive pictures and images. Light also triggers the sending of information throughout various brain centres which stimulate or inhibit the nervous system. Coloured filters are prescribed to help balance the sympathetic and parasympathetic nervous system. The balancing of these two systems helps to reduce visual symptoms.

Did you Know? Syntonic therapy has been used by optometrists for over 70 years to help a variety of visual symptoms.

Who would benefit from Syntonic Optometry Therapy?

Syntonic therapy is prescribed to children and adults based on symptoms, vision assessment, visual/motor testing, and peripheral vision sensitivity. Syntonic therapy has been found successful in patients who have amblyopia and strabismus, reading and learning dysfunctions, acquired brain injuries, and binocular vision dysfunctions. It has also been a useful tool in visual training for high level athletes. 

Syntonic therapy can benefit people who are experiencing:

  • Headaches and migranes
  • Extreme light sensitivity
  • Eye strain and/or visual fatigue
  • Poor concentration and/or attention difficulties
  • Eye turn or lazy eye
  • Reduced athletic performance
