Purpose : This study investigated the effects of alcohol consumption and electronic device use on dry eye symptoms in university students, according to contact lens wear. Methods : Thirty-two university students(64 eyes) were divided into contact lens-wearing (n=16) and non-wearing(n=16) groups. Blink rate, non-invasive tear breakup time(NIBUT), and Occutube test were measured at baseline, after 20 minutes of smartphone viewing, and after alcohol intake(target blood alcohol concentration 0.03%). Results : NIBUT was consistently lower in the non-wearing group, with significant differences after baseline and device use(p=0.010, p=0.001), and borderline significance after alcohol (p=0.057). Occutube values were higher in the non-wearing group, with significance after alcohol(p=0.016). The non-wearing group showed significant blink rate and Occutube changes after device use(p=0.001, p=0.000), and significant changes in all parameters after alcohol (p=0.039, p=0.000, p=0.000). In the wearing group, blink rate changed significantly after device use(p=0.034), and Occutube test after alcohol(p=0.008). Dry eye symptom prevalence increased after device use in the non-wearing group(p=0.028) and after alcohol in the wearing group (p=0.022). Conclusion : Alcohol consumption and electronic device use may exacerbate dry eye symptoms in university students, regardless of contact lens wear.
