Dyslexia in Kids Not Caused by Vision Problems

Nno association between severe reading impairment (SRI) and strabismus ("squinting"), motor fusion (eye coordination), sensory fusion at a distance, refractive error (need for glasses), amblyopia ("lazy eye"), convergence (focus), accommodation, or contrast sensitivity (eye chart).The authors state that ophthalmic intervention should not be the main focus of dyslexia management, and "intensive interventions involving instructions on phonics, word analysis, and reading fluency comprehension" may produce better results. "There is a lack of robust epidemiologic evidence to suggest that [ophthalmic] therapies are effective in improving outcomes for those with dyslexia," they concluded.
