Aim: This study aim to determine relation of Brightness and eye distance with Asthenopia symptoms on class X computer network engineering majors students in Utama Bakti Vocational High School Palembang.
Method: this research uses the analytical method with cross sectional design and the sample consisted of 72 respondent. Data?s collection using observation sheet and Asthenopia?s questioner. The data analyzed with Kendall?s Tau and Fisher Exact Test.
Result: the resul of this research are 63 (87,50%) Light Asthenopia, 47 (65,30%) not adjusted Brightness and 29 (40,30%) eye distance >50,80cm Fisher Exact Test result found no relation between Brightness with Asthenopia p = 1,00 and Kendall?s Suggestion : Computer users need to managing a good eye rest such as every 20 minute look at something 20 feet away for 20 second to prevent Asthenopia.
