Vision Therapy & Reading Difficulties

Reading difficulty and eye symptoms need different assessments

Blur, double vision and discomfort with near work can make reading unpleasant. They do not establish that a child's reading difficulty, attention problem or learning disability is caused by the visual system. An eye examination and an educational or developmental assessment may both be appropriate.

What convergence-insufficiency research supports

Convergence insufficiency affects how the eyes work together at near. In the NIH-funded CITT-ART trial, office-based vergence/accommodative therapy improved clinical measures of convergence in children with that diagnosis. It did not improve standardized reading scores more than placebo therapy.

Do not promise academic outcomes

Vision therapy should not be described as a proven treatment for dyslexia or ADHD, or a guaranteed way to improve reading comprehension, school grades or intelligence. Evidence for one diagnosed binocular-vision condition should not be generalized to all forms of visual training or phototherapy.

Planning care for your child

Bring screening results, current glasses and information about symptoms and school concerns. Ask which diagnosis is being treated, what evidence supports the proposed activities and how progress will be measured. Continue appropriate reading instruction and educational support rather than replacing them with eye exercises.
