Summary

This study compares two behavioral interventions—Baduanjin (a gentle 10-15 minute exercise) or laughter exercises using a smartphone app—plus artificial tears, against artificial tears alone for treating dry eye disease. About 540 adults aged 18-45 with moderate dry eye will participate for 12 weeks, with follow-ups up to 48 weeks. The main goal is to see if these activities improve eye discomfort and vision-related quality of life.
