In his video, Stefan Svartling breaks down common causes of eye strain while reading digital content on devices like e-ink eReaders, smartphones, and tablets, and offers simple solutions for each.
Main Causes of Eye Strain (Ranked Worst to Least Harmful):
- Reflections:
- Most severe. Causes the eyes to constantly refocus, especially if the reflected object is moving (like a ceiling fan or people behind you).
- Fix: Use matte screen protectors, adjust your position to avoid light sources behind you, or use e-ink screens.
- Glare:
- Harsh lighting or screen angle issues make text hard to read.
- Fix: Adjust screen angle, use anti-glare screen protectors, or change lighting in your environment.
- Too Bright Screens:
- Common issue indoors where people don’t reduce screen brightness, leading to headaches or migraines.
- Fix: Adjust brightness and contrast to suit your environment. Try auto-brightness or night mode.
- Nearby Bright Light Sources:
- A bright window behind or beside the screen (e.g., south-facing desk setup) can worsen visibility.
- Fix: Pull the blinds/curtains, reposition your desk, or use diffused lighting.
- Text Too Small:
- Small fonts cause eye fatigue and slow reading.
- Fix: Increase font size and choose easy-to-read fonts (e.g., sans serif or serif optimized for screens).
- Light Too Blue:
- Not always a major factor in eye strain unless screen is also very bright.
- May affect sleep for some.
- Fix: Use blue light filters, warm color modes, or apps like Night Shift / f.lux.
General Tips for All Devices:
- Prefer e-ink for longer reading sessions.
- Use dark mode or sepia where possible.
- Keep screens clean to reduce unnecessary reflections.
- Take regular eye breaks (20-20-20 rule: every 20 mins, look at something 20 ft away for 20 seconds).
