Clinical, prospective, comparative, controlled, single-blind study, on the signs and symptoms of dry eye before and after 3 days of playing video games with the use of artificial tears (Hyabak) versus no intervention.
Adult attendees to a Gamers convention will complete questionnairs and undergo an opthalmological evaluation before and after playing for 3 days in a row. Participants will be randomized into 2 groups of equal size: 1. Study group. 2. Control group. The Study group will instill hyaluronic acid 0.15% artificial tears in both eyes 4 times a day during the 3 days of the video game session, while the control group will not instill artificial tears.
