This study investigates university students’ patterns of screen use and their perceived impact on focus, mental well-being, and academic performance. Based on a survey of 94 undergraduate students, the findings reveal that most students engage with screens constantly, especially via mobile phones. While screens facilitate academic work, students also report frequent distraction, emotional fatigue, and procrastination, suggesting a complex relationship between screen use and academic outcomes. The study calls for greater digital self-regulation and institutional support to help students develop healthier digital habits.
