Abstract : The rapid increase in digital device usage among students has raised growing concerns regarding its effects on visual comfort and sleep health. A cross-sectional observational study was carried out among students with refractive errors, including myopia, hyperopia, and astigmatism, to evaluate the association between screen time and sleep quality. Information related to daily screen exposure, digital eye strain symptoms, and sleep quality was obtained using a structured questionnaire along with the Pittsburgh Sleep Quality Index (PSQI). The study demonstrated that prolonged digital device usage was associated with poorer sleep quality and a higher prevalence of symptoms such as eye fatigue, headache, dryness, and blurred vision. These findings emphasize the potential impact of excessive digital screen use on both ocular health and sleep patterns among students with refractive errors.

Keywords : Screen Time; Sleep Quality; Refractive Errors; Digital Eye Strain; Myopia; PSQI.
