How Do I Reduce Eye Strain From My Computer?

Reduce eye strain by following the 20-20-20 rule (every 20 min, look 20 feet away for 20 sec), consciously blinking more, using lubricating eye drops, positioning your screen at arm's length with the top at eye level, reducing glare, and ensuring proper lighting. Take regular breaks and consider using a humidifier if your environment is dry.

The 20-20-20 Rule

This is the most important habit for preventing eye strain. Every 20 minutes, look at something 20 feet away for at least 20 seconds. This gives your eye muscles a break from focusing at screen distance.

Set a timer. Use an app. Put a sticky note on your monitor. Whatever it takes to remember. This one habit prevents more eye strain than any other intervention.

Blink More

You blink 60% less when using screens. Consciously remind yourself to blink fully and regularly. It feels weird at first, but it keeps your eyes lubricated.

Use Lubricating Eye Drops

Artificial tears help compensate for reduced blinking. Use preservative-free drops if you're using them frequently. Put them in before your eyes feel dry— prevention works better than treatment.

Optimize Your Setup

  • Distance: Screen should be arm's length away (20-26 inches)
  • Height: Top of screen at or slightly below eye level
  • Angle: Screen tilted back 10-20 degrees
  • Text size: Increase if you're squinting or leaning forward

Fix Your Lighting

Your screen shouldn't be the brightest thing in the room. Use bias lighting (a light behind your monitor) or work in a well-lit space. Reduce glare from windows with blinds or repositioning.

Consider a Humidifier

Dry office air makes dry eyes worse. A small humidifier at your desk can help, especially in winter.

Get Regular Eye Exams

Uncorrected vision problems make eye strain worse. Even small prescription changes matter when you're looking at screens 8 hours a day.
