Most of us spend a big part of the day looking at screens, from the work laptop to the tablet the kids borrow after dinner. All that screen time can leave your eyes tired and sore, and it can also bring on headaches.
Thankfully, digital eye strain is usually short-lived. For most people, symptoms ease within a few minutes to an hour after stepping away from the screen, though they can linger for days if you keep going without breaks.
What Digital Eye Strain Feels Like
Digital eye strain, also called computer vision syndrome, is a group of eye and vision problems that can show up after long stretches on a phone, tablet, or computer. People who spend 2 or more hours in a row on a screen each day are at highest risk.
Common Symptoms to Watch For
Your eyes usually let you know when they’ve had enough. Watch for:
- Tired, achy eyes
- Blurry vision
- Dry eye
- Trouble focusing
- Neck and shoulder pain
How Long Digital Eye Strain Usually Lasts
Most of the time, the discomfort fades fast. Give your eyes a break, look away from the screen, and you might feel better within a few minutes or an hour.
Recovery can take longer if you work straight through the day. Hours of screen time without a pause can leave your eyes sore well into the next morning, especially if you’re also dealing with dry eye.
Some people notice blurry distance vision that lingers even after they close the laptop. And if nothing changes about the cause, the strain tends to come back every time you sit down at a screen.
What Causes Digital Eye Strain
Your eyes are built to move and refocus. Locking onto one screen for hours asks them to hold still in a way they don’t love. Letters on a display often look less crisp, and glare from windows or overhead lights can make them harder to see.
You also blink less when you’re focused on a screen, which can leave your eyes feeling dry and gritty. If you lean toward the monitor or tilt your head to see clearly, your neck and shoulders may ache by the end of the day.
Underlying Eye Conditions to Know
Even a small, uncorrected vision problem can make screen time harder on your eyes. A few common ones include:
- Farsightedness, which can make close-up work tiring
- Astigmatism, which can make things look blurry at any distance
- Presbyopia, the age-related loss of up-close focus that usually starts in your 40s
- Eye coordination problems, when your eyes have trouble working together
How to Relieve Digital Eye Strain
Small changes to your setup and routine can help your eyes feel better faster. Start with these:
- Follow the 20-20-20 rule. Every 20 minutes, look at something 20 feet away for 20 seconds.
- Lower your screen a little. Set it 20 to 28 inches from your eyes, with the center about 4 to 5 inches below eye level.
- Cut down on glare. Angle your screen away from windows and overhead lights, and match the brightness to the room.
- Blink often. Lubricating eye drops can help when your eyes still feel dry.
Little changes add up over a workweek. A humidifier can improve the air quality around your desk, which helps when your eyes feel dry. Computer or anti-fatigue glasses can reduce the effort your eyes put in during screen time. And when you can, step away and limit hours of nonstop screen time.
When to See an Optometrist for Digital Eye Strain
Small changes usually do the trick. Still, some signs mean it’s time to book an appointment. Book a visit if you notice:
- Symptoms that last for days, even after you’ve changed your habits
- Headaches that keep coming back after screen time
- Blurry vision that doesn’t clear up after a break
- Trouble reading, working, or driving because of your symptoms
A comprehensive eye exam can help your optometrist find what’s behind your symptoms. Your optometrist may also check how well your eyes focus and work together at the distance you usually sit from your computer.
