Out of this 71% suffered convergence insufficiency was. Conclusion: this study shows that a large number of myopic patients after correction with headache who have normal visual acuity may be suffering from convergence insufficiency. Near work is a single important contributing factor. The study highlights the importance of Orthoptic examination and convergence exercises in all cases of eye strain and headache.
