Method: Cross-sectional survey
Sample: 161 participants
Evidence: Strong effect

A significant portion of radiology professionals suffer from Computer Vision Syndrome (CVS), characterized by symptoms like headaches and eye strain, primarily due to prolonged digital screen use and inadequate workstation ergonomics. This human factors research insight is drawn from a 2025 study published in Journal of Bashir Institute of Health Sciences. Using Cross-sectional survey with 161 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design and implement workstations and display solutions that actively reduce visual strain and promote proper posture for prolonged screen use in medical imaging environments.

Nearly 50% of Radiology Staff Experience Computer Vision Syndrome Due to Poor Ergonomics and Extended Screen Time

Journal of Bashir Institute of Health Sciences · 2025

Key Findings

0149.1% of radiology staff experienced Computer Vision Syndrome.
02The most prevalent symptoms were headache (70.9%), tearing eyes (50.3%), and itching eyes (47.9%).
03Significant risk factors included all-day screen exposure (>5 hours), poor workstation ergonomics (monitors below eye level), and lack of preventive measures.
04Younger staff (20-29 years) and female workers showed a higher susceptibility.

Application

Design takeaway

Design and implement workstations and display solutions that actively reduce visual strain and promote proper posture for prolonged screen use in medical imaging environments.

How to apply

When designing or specifying medical imaging workstations, ensure monitor stands allow for height and angle adjustment to eye level, and consider ambient lighting solutions that minimize screen glare.

Project actions

01When researching user comfort, consider the impact of screen time and workstation setup.
02Investigate common symptoms of digital eye strain and how design can alleviate them.

Method & Evidence

AimWhat is the prevalence of Computer Vision Syndrome and its associated risk factors among radiology staff in Islamabad, Pakistan?

MethodCross-sectional survey

ProcedureResearchers administered the validated CVS-QT questionnaire to radiology employees in Islamabad, collecting data on socio-demographics, screen exposure, ocular symptoms, and preventive practices. CVS was categorized based on symptom scores.

Sample161 participants

ContextHealthcare settings, specifically radiology departments

Variables

IV["Screen time duration","Workstation ergonomics (monitor height)","Preventive practices","Age","Gender"]

DV["Prevalence of Computer Vision Syndrome (CVS)","Severity of CVS symptoms (mild, moderate, severe)","Specific CVS symptoms (headache, tearing eyes, itching eyes)"]

CV["Type of hospital (government/private)","Specific roles within the radiology department (radiologists, technologists, nurses)"]

Strengths & Limitations

Strengths

+Utilized a validated questionnaire (CVS-QT) for symptom assessment.
+Investigated multiple risk factors including screen time, ergonomics, and preventive measures.

Limitations

The study's findings are specific to a particular region and may not apply universally. The subjective nature of symptom reporting can introduce bias.

Reliability & validity

The use of a validated questionnaire enhances the reliability of symptom measurement. The cross-sectional design, however, limits the establishment of causal relationships, impacting internal validity.

Think critically

How might the rapid adoption of digital imaging technologies in healthcare settings, particularly in regions with fewer resources, exacerbate the prevalence of occupational health issues like CVS if design and ergonomic principles are not proactively integrated?

Design Principles

"Ergonomic design for digital displays should prioritize adjustable height and tilt, anti-glare properties, and optimal viewing distances to minimize user fatigue and discomfort."

This highlights a critical occupational health issue impacting the well-being and productivity of professionals in visually intensive fields. Addressing CVS through ergonomic design and workflow adjustments is essential for maintaining a healthy and efficient workforce.

What This Means for Your Design

Many people who work with computer screens all day, like in radiology, get headaches and tired eyes. This study found that almost half of them do, often because their computer screens are too low or they don't take breaks.

How to use in your project

1.Use this study to justify the importance of ergonomic considerations in your design project, especially if it involves digital displays or prolonged screen use.
