Effects of Optimized Blinking Training on Ocular Performance Metrics in Individuals with Computer Vision Syndrome

Purpose: To evaluate the effects of optimized blinking training (OBT) on ocular performance metrics in individuals with computer vision syndrome (CVS).Methods: A double-blind, randomized controlled trial (NCT06913816) was conducted at The Ramzan Eye Care and Optix.Fifty-two individuals diagnosed with CVS participated (17 females, 35 males).Participants were randomly assigned to two groups: the experimental group received OBT, while the control group did not.Ocular performance was assessed using the Visual Function Index Questionnaire (VFIQ) and the Computer Vision Syndrome Questionnaire (CVS-Q) at baseline, mid-treatment, and posttreatment.Data were analyzed using the Kruskal-Wallis and Friedman tests in SPSS version 27.Results: The mean age of participants was 28.63 ± 6.93 years.At baseline, there were no significant group differences in visual function or CVS scores (p > 0.05).Mid-treatment, the experimental group showed significant improvements in visual function (p = 0.05) and CVS scores (p = 0.050) compared to controls.Post-treatment, the experimental group achieved marked gains in visual function (mean = 62.09 ± 6.73, p = 0.01) and significant reductions in CVS symptoms (mean = 6.09 ± 3.28, p = 0.003), while improvements in the control group were smaller and less significant.Within-group analysis confirmed progressive, statistically significant improvements over time in the experimental group (p < 0.05).Conclusion: Optimized blinking training effectively improved visual function and reduced CVS symptoms.It may serve as a safe, non-pharmacological approach to managing digital eye strain among individuals with prolonged screen exposure.
