The purpose of this study is to determine the level of public knowledge about eye health while using gadgets before and after receiving education and to determine the relationship between habitual electronic device use and Computer Vision Syndrome. The design of this research is analytic observational. Data were obtained from questionnaires given before and after education regarding eye health when using gadgets during WFH. Data were analyzed descriptively and presented in frequency table and statistical analysis will be conducted using the Wilcoxon Signed Rank Test, Chi-Square and Contingency Coefficients. The mean scores at pre-test and post-test were 4.84±1.65 and 6.10±1.77, respectively, representing a significant increase in knowledge of eye health by 26.0% (p= 0.000). Habits of using gadgets including duration, distance and use of spectacles correlated with the incidence of Computer Vision Syndrome (CVS) (p=0.016, C=0.168; p=0.010, C=0.181; p=0.035, C=0.181). Eye health education is useful for increasing knowledge and changing people's behavior to prevent fatigue due to the use of gadgets. Inappropriate use of gadgets can increase the incidence of CVS.
