Detailed Description
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:
- Study group.
- 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.
