Aim: To study spasm of accommodation in patients using electronic gadgets for prolonged hours . We studied 76 patients with accommodative spasm out of 300 patients presenting with asthenopia. Most patients were clinically emmetropic.  The probable etiology of the accommodative spasm(AS) for most patients as revealed by case histories was found to be excessive usage of digital screens of  electronic gadgets such as mobile phones , laptops etc. for more than 6 hrs in a day. Treatment consisted primarily of plus reading lenses and cycloplegic drops  along with orthoptic exercises and intermittent rest . Follow up ranged from 10–12 months . Visual symptoms improved for most of the patients.
