Implementing anti-glare screen protectors and ensuring lighting levels of at least 450 lux can significantly decrease the incidence of eye strain and fatigue among individuals working with visual display units. This human factors research insight is drawn from a 2024 study published in Journal of Health Science and Medical Research (JHSMR). Using Cross-sectional study with self-reported questionnaires and objective environmental measurements. with 46 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Incorporate anti-glare features into screen designs and specify minimum lux levels for workspaces to mitigate user discomfort and improve visual performance.

Key Findings

  • 0193.5% of participants did not use anti-glare screen monitors.
  • 0220% of participants had inadequate lighting (less than 450 lux).
  • 0363% reported eye strain, and 60.9% reported eye fatigue.
  • 04Eye fatigue was the most common symptom, with 24% experiencing it more than six times per week.
  • 05Absence of an anti-glare screen increased the likelihood of eye strain by 1.8 times.

Application

Design takeaway

Incorporate anti-glare features into screen designs and specify minimum lux levels for workspaces to mitigate user discomfort and improve visual performance.

How to apply

When designing workstations or specifying office equipment, ensure that screens are equipped with anti-glare coatings and that ambient lighting meets or exceeds 450 lux.

Project actions

  • 01When testing user comfort, consider both objective measurements (like light levels) and subjective feedback (like symptom reporting).
  • 02Ensure your questionnaire is clear and uses a consistent rating scale for symptoms.
03

Method & Evidence

AimTo investigate the association between visual digital unit (VDU) usage and ocular symptoms of Computer Vision Syndrome (CVS) among office workers in Selangor.
MethodCross-sectional study with self-reported questionnaires and objective environmental measurements.
ProcedureOffice workers completed a questionnaire assessing ocular symptoms of CVS on a 5-point scale. Computer screen illumination was measured using a lux meter, and environmental conditions such as lighting sources, window features, and workspace cleanliness were assessed.
Sample46 participants
ContextOffice environments in Selangor, Malaysia, focusing on workers using visual display units (VDUs).

Variables

IV["Presence/absence of anti-glare screen","Lighting levels (lux)"]
DV["Ocular symptoms of Computer Vision Syndrome (eye strain, eye fatigue, eye redness)"]
CV["Number and type of light sources","Window presence and size","Window treatments","Lighting fixture placement","Workspace cleanliness"]

Strengths & Limitations

Strengths

  • +Combines subjective user reporting with objective environmental measurements.
  • +Addresses a prevalent and practical issue in modern workplaces.

Limitations

The findings are specific to the tested environment and may not generalize to all office settings or VDU types.

Reliability & validity

Reliability could be improved with standardized symptom assessment tools and repeated measurements. Validity is supported by correlating objective measures (lux meter) with subjective reports, but the cross-sectional design limits causal validity.

Think critically

How might the type of VDU (e.g., LCD vs. OLED, screen size) and the nature of the work (e.g., graphic design vs. data entry) further influence the impact of glare and lighting on ocular symptoms?

05

Design Principles

"Optimize visual ergonomics by controlling screen glare and ambient lighting to reduce ocular strain."

This research highlights a direct link between specific environmental and equipment factors in the workspace and the prevalence of ocular discomfort. Designers and employers can leverage these findings to create healthier and more productive work environments by addressing these modifiable factors.

06

What This Means for Your Design

Using screens that don't reflect light and having enough light in your workspace can stop your eyes from getting tired and strained.

Paragraph starter

Research indicates that the absence of anti-glare screens can increase the likelihood of eye strain by 1.8 times, and inadequate lighting (below 450 lux) affects 20% of office workers, leading to symptoms like eye fatigue. Therefore, incorporating anti-glare features and ensuring sufficient ambient light are critical design considerations for visual display units and workspaces.
