1

Use the 20-20-20 rule

Holding focus at one near distance for hours fatigues the eye muscles. Every 20 minutes, look at something about 20 feet away for 20 seconds to let them relax. The exact numbers are a rule of thumb, but regular distance breaks reliably ease strain.

Try it
Set a timer or app to nudge you every 20 minutes
Look out of a window — the further the better
Stand up while you are at it to break up sitting too
2

Blink on purpose and fight dryness

Screen users blink as little as a third as often as normal — around 5 times a minute instead of 15 — so eyes dry out, and dry eyes are a major driver of strain headaches.

Try it
Do a few deliberate full blinks during each break
Use artificial tears if your eyes feel gritty
Position the screen slightly below eye level so your lids cover more of the eye
3

Fix the lighting and glare

A bright screen in a dark room, or glare bouncing off it from a window, forces your eyes to work harder all day. Matching the screen to the room and killing reflections removes a constant low-grade strain.

Try it
Set screen brightness to roughly match your surroundings
Reposition so windows are not reflecting on the screen
Warm and dim the room lighting in the evening
4

Size up the text and sit back

Squinting at small text and sitting too close are direct, fixable causes of strain. Bigger text and an arm's-length distance cut the effort your eyes are making.

Try it
Increase font size or zoom until reading feels effortless
Keep the screen about an arm's length away
Put the top of the screen at or just below eye level
5

Check your posture — it may start in your neck

Hunching toward a screen strains the neck and shoulders, and that tension refers up into headaches. Often the "screen headache" is really a posture headache. The pull to keep staring has its own fixes — see doomscrolling.

Try it
Raise the screen so you are not looking down at it
Drop your shoulders and unclench your jaw
Take a short movement break every hour

What didn't make the list

Blue-light glasses

The American Academy of Ophthalmology says there is no evidence that screen blue light damages your eyes, and trials have not shown blue-light glasses reduce eye strain. The breaks, dryness and posture fixes do the real work.

Pushing through with painkillers

They mask the headache while the cause — strain, dryness, posture — keeps going. Fix the setup rather than medicating a daily headache.

Questions people ask

Are screens damaging my eyes?

No. Leading ophthalmology bodies say screen use causes temporary strain and discomfort, not permanent damage. The headaches are real, but your eyes are not being harmed.

When should I see someone?

If headaches are frequent, severe, or come with vision changes, see an optometrist or doctor. You may simply need an eye test, or there may be another cause worth ruling out.
