Patients report to eye care practitioners with symptoms of eyestrain, headaches, blurred vision etc. These conditions are generally missed out unless a complete orthoptic and binocular vision examination is performed. Treatment of these conditions is very successful with vision therapy, lenses and prisms. Successful treatment leads to a significant improvement in the quality of life of the patients. This study was aimed towards finding the prevalence of non-strabismic binocular vision disorders in patients complaining of asthenopia.enAsthenopiaPrevalenceNon strabismic binocular vision disordersOrthoptic evaluationArticle
