How to reduce eye strain with the 20-20-20 rule

Most Australians spend long stretches looking at phones, laptops and televisions each day. Digital eye strain, also called computer vision syndrome, can develop when the eyes focus repeatedly at close range, blink less often and work under bright or poorly positioned screens. Common symptoms include blurred vision, dry or sore eyes, headaches and tired-looking eyes.

The 20-20-20 rule offers a simple way to interrupt that pattern. It can reduce screen fatigue by giving your eyes and posture time to relax, but it works best alongside sensible display settings, regular blinking and professional eye care when needed.

Why digital eye strain happens

Screens demand sustained focusing, yet the natural action of blinking drops significantly during computer and phone use. Fewer blinks can leave the surface of the eye dry, while continuous focus may make the focusing muscles tire. Glare, low contrast and a display positioned too high or too low can add to the discomfort.

Keeping up with the latest current affairs coverage may involve switching between articles, social feeds and videos, particularly during election periods. People often ignore early warning signs such as squinting, watery eyes or tension around the eyebrows, even when screen time is the obvious cause.

What the 20-20-20 rule involves

The approach is straightforward: every 20 minutes, look at something about 20 feet away, or roughly six metres, for at least 20 seconds. A distant window, doorway or noticeboard works well. The aim is to shift your focus away from close-up detail and encourage a few complete blinks.

You do not need a specialist app to begin. Use a phone alarm, a smartwatch timer or an existing calendar reminder. If you often lose track of time while working, start with five resets during the working day and gradually add more. The technique is most useful when combined with an overall reduction in unnecessary screen use.

Set up a screen-friendly workspace

Place your main monitor roughly 50 to 70 centimetres from your eyes, with the top of the screen at or slightly below eye level. This position reduces both the effort required to focus and the tendency to lean forward. Brightness should match the surrounding room rather than the brightest object visible in your reflection.

Australian daylight can be demanding on screens. Afternoon sun can create glare in Brisbane and Perth, while Melbourne’s changeable conditions may repeatedly alter the light around a monitor. Angle displays away from windows, close curtains that reflect onto the screen and use adjustable task lighting rather than overhead glare.

If you regularly work on a laptop, raise it on a stand and connect a separate keyboard and mouse. External monitors can be positioned independently, while laptop stands help prevent a hunched posture that contributes to neck and shoulder ache. Take a short standing break whenever you change tasks.

Fit breaks into Australian routines

Commutes offer natural opportunities to rest your eyes. On a Sydney train, Melbourne tram or Brisbane bus, look through the window instead of checking a phone. Watching the passing scenery gives your focusing muscles a break, although avoid staring directly at the sun. Listening to a podcast can reduce visual demand without requiring silence.

Hybrid work has blurred the boundary between the office and home for many Australians. Emails and messages can continue late into the evening, making it harder to give the eyes a genuine break. Australian workplace expectations vary, and there is no single national right-to-disconnect rule, but employees can discuss reasonable communication boundaries with their manager or consult the Fair Work Ombudsman.

Use familiar cues to make the habit stick. At 3 pm, make your cuppa an “arvo reset” for your eyes and shoulders. Even spending 20 seconds away from the display can help interrupt a cycle of squinting and reduced blinking.

Practical adjustments for screen-heavy days

Small changes can improve comfort during busy periods at home, in a shared office or on the move.

At the desk:

• Keep an upright glass of water nearby and take deliberate blinks when you refocus.
• Increase text size instead of bringing the screen closer to your face.
• Use dark mode in low-light settings and standard mode in brighter surroundings.
• Position frequently used tabs and documents in a stable, comfortable layout.

Away from the desk:

• Put the phone down while eating, travelling or having a conversation.
• Look beyond the screen during television advertisements and video-call pauses.
• Use voice control or larger text when reading for extended periods on a small phone.
• Step outside for a short walk when your eyes feel tired rather than continuing through the discomfort.

Persistent dryness, double vision, flashes of light or a sudden change in vision should not be managed with screen breaks alone. An optometrist can assess the cause and recommend suitable lenses, drops or treatment.

Separate helpful habits from eye myths

Blue-light glasses have become heavily marketed for digital eye strain, but major optical guidance does not find strong evidence that they improve symptoms for most screen users. Correcting an existing prescription, reducing glare and taking regular breaks is generally more valuable. Anyone who prefers tinted lenses for comfort should discuss them with an optometrist.

Some people believe that looking farther away for 20 seconds prevents eye disease. It does not. The practice may ease temporary symptoms, but it cannot correct refractive errors, dry-eye conditions or more serious problems. Comprehensive eye examinations remain important, particularly for people whose work or study demands intensive visual concentration.

In Australia, Medicare rebates for routine optometrist services are limited and may depend on eligibility or a referral from a general practitioner. Many people use private health insurance or pay directly, so scheduling preventive check-ups should be planned rather than postponed until symptoms become severe.

Make eye care an automatic habit

A sustainable routine needs a clear trigger and a visible reminder. Pair the 20-minute reset with an action you already perform, such as answering an email, joining a meeting or finishing a drink. Keep a distant object in view so that shifting focus requires no effort.
