The President of College of Syntonic Optometry

Welcome to the College of Syntonic Optometry!

Thank you for taking the initiative to increase your knowledge of Syntonic optometric phototherapy.  The College of Syntonic Optometry (CSO) is dedicated to helping doctors of optometry better understand how to use Syntonic optometric phototherapy to assess and treat patient’s visual conditions.

New developments in research have shown a wide variety of applications for light therapy. Thus, the use of using Syntonics within the profession of optometry is growing rapidly. Patients diagnosed with learning-related vision problems, binocular vision disorders, strabismus, amblyopia, or traumatic brain injury have clinically shown improved outcomes with syntonic phototherapy.

It is paramount that we understand the complex mechanisms and learn how to best safely and accurately apply phototherapy treatments to our patients.

The first step is to participate in the CSO 101 introductory course. After completing this course, you will want to further your knowledge by attending the Syntonics 201 Course and the Annual Conference.

The CSO website will aid both new and seasoned members in gaining more knowledge about Syntonic optometric phototherapy.

As the President of CSO I will work to improve the understanding and application of Syntonic optometric phototherapy. Our CSO Board will work together to…

  • Develop a white paper that defines Syntonic optometric phototherapy
  • Support phototherapy research 
  • Grow our membership
  • Increased availability of the basic and the advanced phototherapy courses
  • Increase the number of CSO Fellows

The strength of any organization is reflected in the qualification of its Board. I am humbled when I think of the high quality of knowledge and expertise sitting around our board table. These individuals are dedicated to advancing the field of Syntonic optometric phototherapy. We are blessed to have diligent, high-quality administrators to help with the day-to-day workings of our organization.
