My son C was diagnosed with fairly severe tracking issues at his annual eye exam in the fall of 2016 at the age of 9. He could not track objects without moving his entire head. He also had sensitivity to light, watering eyes, and he would pull at the bottom of his eyelids to stretch them out. We thought for years those symptoms were caused by allergies, but came to find out they were associated with his vision issues. After being referred to Denver Vision Therapy and completing 30 weeks of vision therapy, C can now track objects, see clearer, and all his symptoms are gone.
