Visual Fatigue and Display Ergonomics
A Clear Screen Can Still Blur a Critical Decision
Long periods of close visual work can produce dry eyes, headaches, blurred focus and slower recognition even when the display itself remains sharp. In a control room, office or inspection station, that discomfort can make small changes, alarm details and abnormal trends easier to miss. Visual health is supported by a readable workstation, regular changes of focus and prompt attention to symptoms—not by leaning closer and forcing concentration.
Controls to confirm
- Set the display at a comfortable viewing distance and height, enlarge text and critical information where needed, and control glare, reflections and extreme contrast without dimming the workspace below safe levels.
- Change visual focus regularly by looking away to a distant point, blink deliberately, vary screen-intensive tasks where practicable and use planned recovery pauses before fatigue affects monitoring or judgement.
- Report persistent eye strain, headache, double or blurred vision and difficulty reading alarms or instruments; review the workstation and obtain appropriate occupational-health or vision assessment instead of self-adjusting critical display settings indefinitely.
Today’s action
Review one display workstation today for viewing distance, text size, glare, lighting and the user’s ability to change focus without losing operational coverage.
