Eyes, lighting, glare and visual comfort

Display screen work does not cause permanent eye damage but can produce tired eyes, discomfort, temporary visual fatigue and headaches. Optical staff may be attentive to patients' vision yet overlook their own visual comfort.

Common visual comfort problems

• glare from shopfront windows, display lighting or bright overhead lights
• reflections on screens or glossy surfaces
• screens set too bright, too dim or at an awkward angle
• text size that is too small for comfortable reading
• dirty screens, flicker or poor focus
• long periods of concentrated screen work without breaks or changes of activity

Simple checks

Position screens to reduce glare and reflections where possible. Adjust brightness and contrast to suit the ambient light. Increase text size or use zoom features when available. Keep screens clean following local procedures. Change visual focus and posture regularly during prolonged admin or image review tasks.

DSE eye tests and special DSE glasses

Visual comfort is part of DSE safety. Glare, reflections, small text and long screen spells should be managed, not normalised.
