Spending long hours on computers, phones, and tablets can cause digital eye strain (also called computer vision syndrome). Symptoms often include:

  • Tired, burning, or itchy eyes
  • Blurred or double vision
  • Headaches
  • Neck and shoulder pain
  • Difficulty focusing between screen and distance

Below are evidence-based, practical ways to reduce eye strain from screens and make your daily screen time more comfortable.

1. Follow the 20-20-20 Rule

A simple, proven habit:

  • Every 20 minutes
  • Look at something 20 feet (about 6 meters) away
  • For at least 20 seconds

This relaxes the eye muscles that work hard to focus at screen distance.

You can:

  • Set a repeating reminder or use focus/break apps (e.g., Stretchly, TimeOut)
  • Use smartwatches or phone timers to nudge you to take a visual break

2. Adjust Screen Brightness, Contrast, and Color Temperature

Your display settings have a big impact on eye comfort.

Match brightness to your surroundings

  • If the screen is brighter than the room, your eyes work harder
  • If it’s too dim, you strain to read

Try to match screen brightness so that white areas of a website look similar to a sheet of paper in the same lighting.

Increase contrast for easier reading

  • Use higher contrast between text and background
  • Avoid low-contrast color combinations (e.g., light gray text on white)

Most operating systems have built-in display and accessibility settings:

Use warmer color temperature, especially at night

Cool, blue-heavy light can be harder on the eyes and may affect sleep. Warmer tones are usually more comfortable.

Built-in options:

You can also try tools like f.lux on some platforms.

3. Reduce Glare and Reflections

Glare forces your eyes to keep re-focusing and can significantly increase eye strain.

Steps to reduce glare:

  • Position your screen perpendicular to windows, not directly in front of or behind them
  • Use curtains, shades, or blinds to control bright daylight
  • Choose a matte screen or use an anti-glare screen filter on glossy displays
  • Avoid bright lights directly behind you (they reflect in the screen)
  • Use indirect or diffused lighting instead of strong overhead spotlights

If you wear glasses, consider anti-reflective (AR) coatings to reduce glare on lenses.

4. Optimize Your Workstation Ergonomics

Eye strain is closely linked with your overall posture and workspace setup.

Ideal screen position

  • Distance: About an arm’s length away (roughly 50–70 cm)
  • Height: Top of the screen at or slightly below eye level
  • Angle: Screen tilted slightly back (10–20°)

This helps your eyes maintain a natural, slightly downward gaze and reduces neck strain.

Use proper font size

  • Increase text size so you can read comfortably without leaning forward or squinting
  • Many apps and browsers allow you to set a default larger font size or zoom level

Guides you can follow:

5. Blink More and Prevent Dry Eyes

When staring at screens, people tend to blink less, which dries out the eye surface and causes irritation.

To reduce dryness:

  • Consciously remind yourself to blink fully and regularly
  • Follow the 20-20-20 rule to break long staring sessions
  • Use artificial tears (lubricating eye drops) if recommended by your eye doctor
  • Avoid direct air from fans, air conditioners, or heaters blowing at your face

If you’re a contact lens wearer and feel dryness or discomfort at the computer, discuss:

  • Different lens materials
  • Reduced wear time
  • Using lubricating drops suitable for contacts

with your optometrist or ophthalmologist.

6. Use Blue Light and Dark Mode Wisely

Blue light: what matters and what doesn’t

Research suggests that blue light isn’t likely to damage your eyes directly, but it may:

  • Disrupt your sleep–wake cycle if you use bright screens late at night
  • Make screens feel harsh or glaring for some people

You can:

  • Use night mode / blue light filters in the evening
  • Reduce screen brightness and avoid screens 1–2 hours before bed to support better sleep

More info:

Dark mode vs. light mode

  • Dark mode can feel more comfortable in low-light environments
  • Light mode may be better in bright conditions and for long reading sessions

Choose the mode that:

  • Gives you good contrast
  • Lets you read without squinting
  • Doesn’t make you lean in closer to the screen

7. Limit Continuous Screen Time and Take Regular Breaks

Even with a perfect setup, continuous, uninterrupted screen use is tiring.

Helpful habits:

  • Try 5–10 minute breaks every hour to stand, move, and rest your eyes
  • Alternate screen-heavy tasks with off-screen tasks (phone calls, handwriting, whiteboard work)
  • Build small “screen-free” windows into your day (during meals, walking, or commuting)

Some people use the Pomodoro technique (e.g., 25 minutes of focused work + 5 minutes break) to structure breaks.

8. Get the Right Prescription and Eye Exam

If your vision isn’t properly corrected, your eyes must work much harder at screen distance.

You should:

  • Get regular comprehensive eye exams (adults often every 1–2 years, or as your doctor advises)
  • Tell your eye doctor how many hours a day you use digital devices and at what distances
  • Ask whether special computer or office lenses are appropriate for you

9. Adjust Reading and Display Settings on Devices

Most modern devices include features to improve readability:

On computers

  • Increase system font size and UI scaling
  • Use your browser’s zoom (often Ctrl + / Cmd +) for text-heavy pages
  • Turn on High Contrast or Reader Mode in browsers for long articles

On phones and tablets

  • Increase text size and display scaling in Accessibility or Display settings
  • Enable reader view in browsers to remove clutter and small fonts
  • Avoid reading tiny text in landscape mode if it causes you to squint or lean in

10. Maintain General Health Habits That Support Eye Comfort

Your overall health influences your visual comfort and stamina.

Helpful practices:

  • Stay hydrated – dehydration can worsen dry eye symptoms
  • Eat a balanced diet rich in omega-3 fatty acids, vitamin A, and antioxidants (fish, leafy greens, carrots, nuts)
  • Get regular sleep, which lets your eyes rest and recover
  • Manage conditions like allergies, diabetes, and high blood pressure, which can affect eye health

11. When to See an Eye Care Professional

See an optometrist or ophthalmologist if you notice:

  • Frequent or worsening headaches with screen use
  • Persistent blurred or double vision
  • Eye pain, redness, or sudden changes in vision
  • Eye strain that does not improve after using the strategies above

Sudden vision changes, flashes of light, or a “curtain” over your vision can be an emergency — seek urgent medical care.

Quick Checklist: Daily Habits to Reduce Eye Strain

Use this as a simple daily reference:

  • Follow the 20-20-20 rule
  • Keep screens at arm’s length and slightly below eye level
  • Match screen brightness to room lighting
  • Use warmer tones and possibly Night Mode in the evening
  • Reduce glare from windows and lights
  • Blink often and consider lubricating drops if advised
  • Increase font size and zoom instead of squinting
  • Take 5–10 minute breaks every hour
  • Get regular eye exams and use the correct prescription

Implementing even a few of these changes can significantly reduce digital eye strain and make your screen time more comfortable and sustainable.
