Today, we are thrilled to welcome back Dr. Devin Duval, OD, FCOVD. Dr. Duval is an optometrist with advanced residency training in pediatrics, vision therapy, and vision rehabilitation. He is a Fellow of the College of Optometrists in Vision Development (FCOVD) and a member of the Neuro-Optometric Rehabilitation Association (NORA). As an associate professor at Rocky Mountain University and one of only a few optometrists in Utah with this specific expertise, he specializes in helping patients with post-concussion vision problems, strabismus, and other complex visual conditions.
In this episode, Dr. Devin Duval returns to the Concussion Coach Podcast for an in-depth discussion on Syntonics and other vision-related aspects of concussion recovery.
What is Syntonics? Dr. Duval explains that Syntonics is the application of selective light frequencies to the eyes to treat various vision conditions. It works by balancing the autonomic nervous system, helping patients move out of a chronic "fight or flight" (sympathetic) state and into a "rest and digest" (parasympathetic) state.
How It Works: Patients are tested to determine the specific colored filters they need. They then use these prescribed glasses for about 20 minutes a day, looking at a full-spectrum light source like the sky. Treatment typically lasts 1-2 months.
Syntonics vs. Other Colored Glasses: Dr. Duval distinguishes between "band-aid" colored glasses for symptom relief (like FL-41 for migraines) and Syntonic glasses, which are a targeted treatment intended to fix the underlying problem.
Practical Tips for Listeners:
Expanding Visual Fields: Go for walks in open spaces and consciously pay attention to your peripheral vision.
Screen Use & Blue Light: The 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds) is crucial. Blue light filters are generally recommended for concussion patients, but quality varies.
Computer Work: Reduce visual clutter, avoid fluorescent lighting, and consider a "flicker-free" monitor. High-resolution 4K monitors can sometimes be overstimulating.
Finding Help: Dr. Duval emphasizes that many "untreatable" visual problems are treatable with the right specialist. He encourages listeners to seek out a qualified professional.
The episode is a powerful reminder that there is hope and help available for persistent post-concussion visual symptoms.
