Impact of Vestibulo-Ocular Reflex (VOR) Exercise on Visual Fatigue among College Students Wearing Spectacles: A Pilot Study

Visual fatigue is a common condition among individuals who engage in prolonged near-work activities such as reading, studying, or screen time. In recent years, the increasing reliance on digital devices for academic, social, and entertainment purposes has led to a rise in visual fatigue, particularly among college students. This pilot study evaluated the effect of vestibulo-ocular reflex (VOR) exercises on reducing visual fatigue in college students wearing spectacles. Subjective visual fatigue was assessed using the Asthenopia Questionnaire before and after a 6-week intervention. Participants aged 18-28 years were included, and pre- and post-test scores were analyzed using a paired t-test. The mean questionnaire score decreased from 21.40 ± 9.06 at pre-test to 12.08 ± 4.59 at post-test, showing a statistically significant improvement (t = 4.58). The findings suggest that VOR exercises are effective in significantly reducing visual fatigue among spectacle-using college students.
