Digital eye strain, also called computer vision syndrome, describes eye and vision symptoms that can occur or worsen during prolonged use of computers, phones, tablets and other digital screens. Common symptoms include tired or sore eyes, dryness or watering, burning or itching, blurred vision, difficulty refocusing, headaches and neck or shoulder discomfort.
These symptoms are usually temporary and often improve with rest, but they should not automatically be blamed on screen use. An unsuitable prescription, dry eye disease, binocular vision problems and other eye or medical conditions can cause similar symptoms. Sudden vision changes, severe eye pain, flashing lights or a new curtain or shadow in the vision need urgent assessment rather than routine eye-strain self-care.
Quick Answer: What Are the Main Digital Eye Strain Symptoms?
- Tired, sore, burning or itchy eyes.
- Dryness, grittiness or watering.
- Blurred or fluctuating vision during or after near work.
- Difficulty refocusing from a screen to something farther away.
- Headaches after prolonged close work.
- Sensitivity to light or glare.
- Neck, shoulder or back discomfort related to posture or screen position.
- Difficulty concentrating when symptoms build during prolonged screen use.
Healthdirect notes that eye strain can follow prolonged screen use, reading or other visually demanding tasks and may cause sore or itchy eyes, dryness or watering, blurred or double vision, headaches, light sensitivity and neck or shoulder discomfort.

Find an OptometristDigital Eye Strain vs Dry Eye: What Is the Difference?
Digital eye strain and dry eye can overlap, but they are not the same diagnosis. Screen use may worsen dryness because blinking changes during concentrated viewing, while people who already have dry eye may notice more symptoms during screen work.
If dryness, grittiness, burning, watering or fluctuating vision keeps returning, an eye examination can help determine whether dry eye disease, prescription needs or another factor is contributing.
Digital Eye Strain vs an Outdated Prescription
You cannot reliably tell the difference from symptoms alone. Screen-related discomfort may become more noticeable during or after prolonged near work, but an unsuitable prescription can also cause blur, headaches or focusing difficulty. Persistent symptoms deserve an eye examination rather than assuming the cause is either digital eye strain or a prescription change.
Does Blue Light Cause Digital Eye Strain?
Current evidence does not support blue light from ordinary digital screens as the main cause of digital eye strain. A 2023 Cochrane review found that blue-light filtering spectacle lenses may not reduce short-term eye strain compared with non-blue-light filtering lenses, and evidence for sleep-related benefits remains uncertain.
For a full evidence review, see Blue Light Glasses Australia: Do You Need Them?. This keeps blue-light product claims separate from the symptom-focused role of this page.
Can Digital Eye Strain Cause Permanent Eye Damage?
Digital eye strain is generally uncomfortable rather than a cause of permanent eye damage. Healthdirect describes eye strain as common and usually relieved by resting the eyes. However, ongoing symptoms can affect comfort, concentration and work, and they can overlap with other eye problems that do require assessment.
Do not use a diagnosis of digital eye strain to explain sudden vision loss, a sudden marked change in vision, severe pain or other urgent eye symptoms.
When Should You Arrange an Eye Examination?
Arrange an eye examination when symptoms keep returning, interfere with work or study, or do not settle with reasonable changes to screen habits and rest. An optometrist can assess vision, the current prescription, eye health and other factors that may contribute to symptoms. The exact tests depend on the person and the clinical findings.
Symptoms worth discussing with an optometrist
- Persistent or recurrent blurred vision.
- Frequent headaches associated with close work.
- Repeated difficulty refocusing between near and far distances.
- Ongoing dryness, burning, grittiness or watering.
- Double vision.
- Symptoms that continue despite breaks and a comfortable screen setup.
- A current prescription that no longer feels clear or comfortable.
When Digital Eye Strain Symptoms Need Urgent Care
Seek urgent medical assessment for a sudden change in vision or sudden vision loss. Healthdirect advises immediate assessment for sudden vision changes and other serious eye symptoms.
- Sudden loss of vision or a sudden marked change in vision.
- New flashing lights, a sudden increase in floaters, or a new shadow or curtain in the vision.
- Severe eye pain.
- A painful red eye or marked sensitivity to light.
- An eye injury or chemical exposure.
- Sudden blurred vision with facial droop, weakness or numbness, loss of balance or slurred speech — call triple zero (000) because these can be signs of stroke.
These symptoms should not be attributed to computer use or managed by buying new glasses without medical assessment.
What Can You Do for Mild Screen-Related Eye Strain?
Because this page is intended to remain the AMV symptom and assessment guide, practical management is kept brief. Healthdirect recommends regular breaks, including the 20-20-20 approach: every 20 minutes, look at something about 20 feet (6 metres) away for 20 seconds. Adjusting screen position, text size, contrast and glare can also help.
For the step-by-step management and workstation guide, read How to Reduce Digital Eye Strain.
Do You Need Special Computer Glasses?
Not everyone with screen discomfort needs a special pair of glasses. If your prescription is suitable and your screen distance is comfortable, changes to breaks and setup may be enough. Some people with particular prescription or working-distance needs may benefit from a lens design intended for near and intermediate tasks, but this should be based on an individual assessment rather than a generic screen-time threshold.
Anti-reflective coatings can reduce reflections from spectacle lens surfaces, but they do not treat every cause of digital eye strain and should not be described as essential for all screen users.
If lens reflections are part of the problem, read AMV’s anti-reflective coating guide.
Digital Eye Strain in Children
Children can experience eye strain during prolonged phone, tablet, computer or gaming use. Healthdirect recommends regular breaks and time outdoors. Blurred vision, headaches, squinting or other recurring symptoms should not automatically be attributed to screens because children can also have refractive or binocular vision issues that need assessment.
There is no evidence-based rule that every child using screens needs blue-light glasses. If symptoms persist or a parent or carer has concerns about vision, arrange an eye examination.

Frequently Asked Questions
What does digital eye strain feel like?
It can cause tired, sore, burning, itchy, dry or watery eyes, blurred vision, trouble refocusing, headaches and neck or shoulder discomfort. Symptoms vary and can overlap with other eye conditions.
How do I know if I have digital eye strain or need a new prescription?
Symptoms alone cannot reliably distinguish the two. If blur, headaches or focusing difficulty keep returning, an eye examination can check the prescription and other possible causes.
Can digital eye strain cause permanent damage?
Eye strain is generally temporary and usually improves with rest. Persistent symptoms still deserve assessment because other eye problems can cause similar discomfort.
Do blue light glasses help digital eye strain?
Current evidence does not show a clear short-term eye-strain benefit from blue-light filtering spectacle lenses compared with non-filtering lenses. They should not be treated as a routine requirement for screen users.
What is the 20-20-20 rule?
Every 20 minutes, look at something about 20 feet (6 metres) away for 20 seconds. It is a simple reminder to interrupt prolonged near focus and is recommended by Healthdirect as one way to help prevent eye strain.
Why do my eyes feel dry when I use a computer?
Concentrating on a screen can reduce blinking, which can make the tear film evaporate more quickly. Dry eye disease or other ocular-surface problems can also contribute, so persistent symptoms may need assessment.
Are computer glasses different from reading glasses?
They can be. A lens designed for an intermediate computer distance may use a different prescription or lens design from standard reading glasses. The correct working distance depends on your setup and prescription.
Can children get digital eye strain?
Yes. Children can experience eye strain during prolonged screen use. Regular breaks and outdoor time can help, but recurring symptoms or vision concerns should be checked rather than assumed to be screen-related.
How often should I have an eye test if I use screens all day?
Screen time alone does not create one fixed examination interval for everyone. Timing depends on symptoms, age, eye-health findings, prescription and individual risk factors. Arrange an assessment sooner if symptoms persist or vision changes.
