Accommodative Facility and Vergence Facility after Mobile Gaming

Abstract

Aim: This study aimed to access the changes of accommodation and vergence before and after mobile gaming. Settings and Design: This was a comparative study conducted in the outpatient department of ophthalmology. Accommodative facility and vergence facility were measured using flippers. Methods and Materials: A comparative study was conducted on 50 healthy subjects, in both males and females, with age groups ranging between 18 and 30 years. This study has been approved by the IRB Committee; 25 young emmetropic patients and 25 young myopic patients were included. The comparison of accommodative facility and vergence facility before and after mobile gaming for 1 h was measured to determine the level of changes in accommodation and vergence. All patients were undergone comprehensive ophthalmic examination including vision, subjective/objective refraction, anterior segment examination, and accommodative and vergence facilities measured using accommodative and vergence flippers. Results: The mean and standard deviation value significantly increase before and after mobile gaming in the right eye, left eye, and both eyes in case of accommodation facility, and there is a decrease in the mean and standard deviation value in case of vergence facility in both eyes before and after mobile gaming. Conclusion: The mean and standard deviation value significantly increase before and after mobile gaming in the right eye, left eye, and both eyes in case of accommodative facility, and there is a decrease in the mean and standard deviation value in case of vergence facility in both eyes before and after mobile gaming.
