Protect Your Eyes at Work: Ergonomic Tips for Screen Users
Overview
Prolonged screen use can cause eye strain, dryness, headaches, and blurred vision. Ergonomic adjustments to your workspace and habits reduce symptoms and protect long-term eye health.
Quick checklist
- Screen position: Top of screen at or just below eye level; center 15–20° below eye level.
- Distance: 20–28 inches (50–70 cm) from eyes.
- Lighting: Even ambient light; avoid glare and reflections.
- Breaks: Follow the 20-20-20 rule (every 20 minutes, look 20 feet away for 20 seconds).
- Blinking: Consciously blink often; consider lubricating eye drops if dry.
- Posture: Sit upright with feet flat, elbows ~90°, monitor directly ahead.
- Display settings: Increase text size, adjust contrast and color temperature; use night/dark mode when appropriate.
- Glare control: Use an anti-glare screen or matte monitor; position monitor perpendicular to windows.
- Sunglasses/blue light: Use UV sunglasses outdoors; blue-light filters or glasses may help comfort but have limited evidence for long-term protection.
Step-by-step ergonomic setup
-
Chair and posture
- Adjust chair height so feet rest flat and knees ~90°.
- Support lower back with lumbar support or rolled towel.
- Keep shoulders relaxed; wrists neutral while typing.
-
Monitor placement
- Place monitor directly ahead, 20–28 in from eyes.
- Top of display at or slightly below eye level; tilt back 10–20°.
- For dual monitors, place primary monitor directly in front and secondary to the side; or position both close together and at same height.
-
Keyboard and mouse
- Keep keyboard and mouse at same height; forearms parallel to floor.
- Use a low-profile keyboard or wrist rest to reduce strain.
- Move mouse closer to avoid overreaching.
-
Lighting and glare
- Use diffuse ambient lighting; avoid bright overhead lights directly above screen.
- Position desk perpendicular to windows; use blinds or shades to control sunlight.
- Add task lighting for paperwork, not for the monitor area.
-
Display settings and software
- Set text size and scaling so you can read comfortably without leaning forward.
- Increase contrast and reduce screen brightness to match room light.
- Enable blue-light/night mode in evening to reduce warm/cool contrast.
- Use larger fonts and high-contrast themes for readability.
-
Breaks and eye exercises
- 20-20-20 rule; every 20 minutes, look at something ~20 feet away for 20 seconds.
- Every 60–90 minutes, stand, stretch, and walk 1–2 minutes.
- Simple exercise: focus on a near object for 5–10 seconds, then a distant object for 5–10 seconds; repeat 10 times.
-
Manage dry eyes
- Blink deliberately while reading screens; take microbreaks to blink fully.
- Use preservative-free artificial tears if needed.
- Maintain humidity (desk humidifier) if air is dry.
-
When to see an eye-care professional
- Persistent eye pain, double vision, significant vision changes, or chronic dryness.
- For regular eye exams: every 1–2 years for most adults; follow optometrist recommendations.
