Screens, Eye Strain and Simple Habits That Help
Long hours on screens can cause dryness, tired eyes and headaches. Most of the relief comes from habits that take seconds rather than expensive equipment.
Screen use is hard on the eyes mainly because people blink less and focus at one distance for long periods. The result is often dryness, a gritty feeling, tired eyes and headaches. Most of these symptoms respond to simple changes.
Take regular breaks
A common approach is to look away from the screen at a distant object for a few seconds every so often. Standing up and moving also helps. The aim is to change focus and to blink more often.
Position and light
Place the screen slightly below eye level and at arm's length. Reduce glare from windows and overhead lights, and match the screen brightness to the room. Text should be large enough to read without leaning in.
Blinking and dryness
Make a conscious effort to blink fully. Air conditioning and heating can dry the air, so a humidifier or a glass of water nearby may help. Artificial tears available without prescription can ease dryness, but ask a pharmacist which product suits you.
When to see an eye doctor
Seek an eye examination if you have persistent blurred vision, double vision, pain in or around the eye, or headaches that are new or worsening. Regular eye checks are also useful as you get older.
This is general information. Eye symptoms that are sudden or severe need prompt medical attention.
