Description Background: Global estimates suggest that nearly 60 million people suffer from Computer Vision Syndrome (CVS).Aim: The goal of this research was to evaluate the effectiveness of an educational intervention using the 20/20/20 rule to reduce CVS symptoms.Setting: The study was conducted in the Qassim University eye clinic.Methods: An experiential intervention study was conducted amongst 40 patients with CVS, with their age ranging from 21 to 38 years. The sample was divided into two groups: (1) intervention patients (n = 20), who were given a structured advice booklet about how to reduce CVS symptoms using the 20/20/20 rule, and (2) control (n = 20) with CVS, who were given advice to simply drink more water. Both groups completed two questionnaires, namely, the CVS-Q and Dry Eye Questionnaire-5 (DEQ-5). Dry eye clinical tests were performed. The same procedures were repeated after 20 days to compare the outcomes before and after intervention.Results: The study findings revealed that patients complaining from dry eye symptoms showed significant changes after the educational intervention (pre-intervention: 9.05 ± 4.32; post-intervention: 7.10 ± 3.61) (p = 0.04). The symptoms of CVS were slightly reduced after educational intervention, from 9.00 ± 3.03 to 8.35 ± 1.89 (p = 0.38). However, TBUT showed a significant increase after the educational intervention (pre-intervention: 6.20 ± 2.02 s; post-intervention: 8.55 ± 2.84 s) (p = 0.005).Conclusion: The educational intervention of the 20/20/20 rule induces significant changes in dry eye symptoms and tear film and some limited changes for ocular surface integrity.
