Eyes, lighting, glare and visual comfort

DSE work does not cause permanent eye damage, but long spells of screen use can lead to tired, uncomfortable eyes, temporary blurred vision and headaches. Screen work can also make people notice existing eyesight problems.

Visual comfort checks

• Screen position: place the screen where you can read it without leaning, squinting or twisting.
• Brightness and contrast: adjust the display so it is clear but not glaring.
• Glare and reflections: avoid positioning screens directly against bright windows, strong lights or reflective surfaces.
• Clean screens: dirt, fingerprints and smears make screens harder to read.
• Text size: use appropriate zoom or display settings rather than leaning forward to read small text.
• Breaks: regular breaks or changes of activity help reduce visual fatigue.

In care settings, lighting is often chosen for residents, ambience or night routines rather than for screen work. Staff may use screens in dim offices, bright reception areas, corridors, staff rooms or medicine rooms. Raise the issue if glare, low light or poor contrast makes screen tasks uncomfortable.

Eye tests and DSE users

For DSE users covered by the regulations, employers must arrange and pay for an eye and eyesight test if the worker requests one. Employers only have to pay for glasses for DSE work when the test shows the worker requires special glasses specifically for the screen-viewing distance and an ordinary prescription is not suitable.

Management controls

Tired eyes and headaches are not signs of weakness. They are prompts to check screen position, lighting, breaks, eyesight and workstation setup.
