Impact of 20-20-20 Rule and Daily Reminders in Relieving Digital Eye Strain

Aim: To assess the impact of taking proper breaks and the role of reminders in enhancing compliance while working on digital devices in reducing the digital eye strain. Methodology: This was a questionnaire-based prospective study determining the role of taking proper breaks and the role of daily reminders in enhancing patient compliance and in-turn reducing digital eye strains. The study examines compliance variations with the 20-20 rule in two distinct groups, Group-I (Subjects who got daily reminders) and Group-II (Subjects who did not get any reminders). The occurrence of symptoms related to digital eye strains were also compared between the subjects in the two groups and from baseline. Results: A significant proportion of respondents were not aware of the 20-20 rule and do not actively implement it. Taking visual breaks reduce digital eye strain as both Group-1 and Group-2 generally have lower symptom prevalence compared to the Baseline group. However, Group-2 tends to have higher symptom prevalence compared to Group-1 indicating that reminders may play an important role in reduction in symptoms of digital eye strain. Conclusion: The 20-20-20 rule is a simple and effective technique to help prevent Computer Vision Syndrome and reduce the risk of Digital Eye Strain caused by prolonged computer use or digital device use. However, a lack of knowledge regarding the 20-20-20 rule prevails and it is important to spread awareness about the importance of visual breaks during digital work. Since getting proper reminders can enhance the compliance, incorporation of reminders in digital devices can be useful for people who often suffer from DES due to lack of proper breaks.
