All participants completed the OSDI. Following routine ophthalmologic examination, the TBUT and Schirmer’s test were undertaken and outcomes were compared.Results: The mean age was 29.09 ± 6.73 (range 20–46) years. Mean OSDI questionnaire, TBUT, and Schirmer’s test scores were detected as 37.12 ± 19.05 (range 4–75), 11.37 ± 3.69 seconds (range 4–18 seconds), and 25.80 ± 8.43 mm (range 6–35 mm), respectively. There was a significant inverse correlation between the OSDI and TBUT scores (r = −0.385, P = 0.022). No significant correlation existed between the OSDI and Schirmer’s test scores.Conclusion: Dry eye is a common problem among computer users. The OSDI questionnaire, used together with the TBUT, is easily performed and may be of benefit in supporting the diagnosis of dry-eye syndrome.Keywords: computer use, dry eye, ocular-surface disease
