Previous studies suggest that excess use of digital devices causes visual discomfort where as yoga has been shown to be useful in reduction of visual discomfort. Earlier studies have not shown the effect of yoga on children using digital devices. With this background, the present study was planned to determine the effect of yoga on visual discomfort among children attending online classes during COVID- 19 pandemic. Twenty children of both sexes and their ages ranged between 8 to 14 years were included in the study. All the participants divided into two groups: (i) Yoga group (YG) and (ii) Control group (CG). The participants were screened to exclude those who (i) had any clinical condition such as Sjögren's syndrome or kerato-conjunctivitis sicca and (ii) Used medication for drying of the eyes. None of the participant had to be excluded based on these criteria. Both group were assessed before and after twenty one days of yoga intervention and visual discomfort were measured using computer vision syndrome questionnaire. The scores of both the groups were comparable at baseline, after twenty one days there was a significantly decreased score in the YG group, whereas the CG showed significantly increased scores. The results suggest that the yoga practice appeared to reduce visual discomfort, while the group who had no yoga intervention (CG) showed an increase in discomfort at the end of twenty one days.
