Sponsor: Zagazig University
Summary
This study is for anyone struggling with dry, tired, or uncomfortable eyes, especially from long hours on screens. Investigators all know that feeling after staring at a laptop or phone too long. This study from Zagazig University looks at a simple habit called the 20-20-20 rule: every 20 minutes, take a 20-second break to look at something about 20 feet away. Investigators want to see if doing this every day, along with participant's regular artificial tears, helps participants eyes feel better than tears alone. If participant join, participant will use artificial tears as usual. Some participants will also be asked to practice the 20-20-20 rule throughout the day. Investigators will follow participant for about 8 weeks and check participant symptoms, tear film, and overall eye comfort with simple eye exams and questionnaires. There is no experimental drug involved, just a daily habit Investigators hope will make standard treatment work better. The study was approved by the Institutional Review Board, Faculty of Medicine, Zagazig University on 07-September-2024.
