Prevalence of dry eye symptoms and associated risk factors among students at Al-Mustaqbal University

What is it about?

It looks at how common dry eye symptoms are among university students in Iraq and what factors increase the risk, especially long hours of using digital devices like smartphones, laptops, and tablets. More specifically, the study: Measured how many students have dry eye symptoms Assessed how severe those symptoms are Examined risk factors, such as: Long daily screen time Being female Academic year (especially senior students) Wearing glasses or contact lenses Considered the impact of Iraq’s dusty, dry environment, which can worsen eye dryness The researchers found that: About 6 out of 10 students had dry eye symptoms Students who used screens more than 7 hours a day were much more likely to have symptoms Female students and contact lens/glasses users were at higher risk Overall, the study highlights that dry eye is a common and preventable problem among students, and it suggests practical solutions like taking screen breaks, improving digital habits, and regular eye screening at universities

Why is it important?

This study is important for several reasons, in simple, practical terms: 1. It shows a common but overlooked problem The study found that dry eye symptoms affect more than half of university students. Many students think eye discomfort is “normal,” but persistent dryness, burning, and blurred vision are real health issues that can worsen over time if ignored . 2. It affects learning and academic performance Dry eye symptoms make reading, computer work, and studying harder. When students have eye pain or blurred vision, they may study less effectively, feel tired faster, and lose concentration—directly affecting academic success . 3. Screen use is increasing—and the risk is growing University life now depends heavily on phones, laptops, and online learning. The study clearly shows that long screen time greatly increases dry eye risk, meaning the problem will likely grow unless preventive habits are adopted . 4. It identifies who is most at risk Knowing that female students, heavy screen users, senior students, and those wearing glasses or contact lenses are at higher risk helps universities and clinicians target prevention and screening more effectively . 5. The environment makes the problem worse Iraq’s hot, dry, and dusty climate increases tear evaporation. This means international data alone is not enough—local evidence is essential for proper public health planning in Iraq and similar regions . 6. The problem is preventable Most risk factors identified—like excessive screen time and poor digital habits—are modifiable. The study supports simple solutions such as: • Regular screen breaks (20-20-20 rule) • Better screen ergonomics • Routine eye check-ups for students
