Method: Cross-sectional study using self-administered questionnaires
Sample: 293 participants
Evidence: Strong effect

Poor ergonomic setups, specifically uncomfortable seating postures and insufficient screen distance, are significant contributors to the high prevalence of Computer Vision Syndrome (CVS) among university students. This human factors research insight is drawn from a 2025 study published in BMC Public Health. Using Cross-sectional study using self-administered questionnaires with 293 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize ergonomic design for workstations and digital interfaces, focusing on comfortable posture and appropriate screen distance, to mitigate the risk of Computer Vision Syndrome.

Uncomfortable seating and close screen distance double the risk of Computer Vision Syndrome in students

BMC Public Health · 2025

Key Findings

0173.7% prevalence of Computer Vision Syndrome (CVS).
02Uncomfortable seating posture and close screen distance were associated with double the likelihood of developing CVS.
03Students who perceived minimal impact of digital technology on their lifestyle and eye health, and those without refractive errors or glasses, were less likely to develop CVS.
04Using screens for entertainment was associated with a lower likelihood of CVS compared to using screens for university study.

Application

Design takeaway

Prioritize ergonomic design for workstations and digital interfaces, focusing on comfortable posture and appropriate screen distance, to mitigate the risk of Computer Vision Syndrome.

How to apply

When designing study spaces, computer labs, or even individual workstations, ensure adjustable chairs, adequate desk height, and clear guidelines on optimal monitor placement to maintain a healthy viewing distance.

Project actions

01When researching user comfort, consider both physical posture and screen interaction.
02Investigate how different usage contexts (e.g., work vs. leisure) affect user experience and well-being.

Method & Evidence

AimWhat are the key ergonomic and behavioral factors associated with the prevalence of Computer Vision Syndrome among university students?

MethodCross-sectional study using self-administered questionnaires

ProcedureAn online questionnaire was distributed to undergraduate students to collect data on their computer usage habits, ergonomic setup, and symptoms of Computer Vision Syndrome.

Sample293 participants

ContextUniversity student population in Oman

Variables

IV["Seating posture","Screen distance","Perception of digital technology impact","Presence of refractive error/glasses use","Primary screen usage context (study vs. entertainment)"]

DVPrevalence of Computer Vision Syndrome (CVS)

CV["Age","Gender","Specific computer hardware used","Duration of daily computer use"]

Strengths & Limitations

Strengths

+Addresses a prevalent issue affecting a large user group.
+Identifies specific, actionable ergonomic risk factors.
+Provides a high prevalence rate for context.

Limitations

The study relies on self-reported symptoms, which may not be entirely accurate. It also doesn't explore the long-term effects of these ergonomic issues.

Reliability & validity

The use of a standardized questionnaire increases reliability. However, the cross-sectional design and self-reported data may affect the validity in establishing causal relationships.

Think critically

How might the perception of digital technology's impact on lifestyle influence an individual's adoption of ergonomic best practices, even when aware of potential risks?

Design Principles

"Optimize physical and digital environments to support user health and comfort, thereby enhancing sustained engagement and reducing strain."

Understanding the direct link between physical setup and visual discomfort is crucial for designers creating workstations, educational environments, and digital interfaces. Addressing these ergonomic factors can lead to improved user well-being and sustained productivity.

What This Means for Your Design

If students sit uncomfortably or too close to their screens, they are much more likely to get eye strain and headaches from using computers.

How to use in your project

1.Reference this study when discussing the impact of ergonomic factors on user health and performance in your design project.
2.Use the findings to justify design choices aimed at reducing eye strain and improving posture.
