As screen use becomes embedded in daily life, optometrists are reporting an increase in patients presenting with symptoms of Digital Eye Strain, particularly among school-aged children.
From online learning platforms to smartphones and gaming devices, Australian families are spending more time than ever focusing on near tasks. While technology provides clear educational and social benefits, eye care professionals warn that prolonged close-up work is placing sustained stress on developing visual systems.
Digital Eye Strain, sometimes referred to as computer vision syndrome, includes symptoms such as headaches, blurred vision, dry eyes, neck tension and difficulty concentrating.
Gary Rodney, creator and founder of Smart Vision Optometry, a Master of Optometry, Behavioural Optometrist and Fellow of the International Academy of Orthokeratology and Myopia Control (FIAOMC) with more than 30 years of experience, says the issue is becoming increasingly common.
“Extended near focus places continuous demand on the accommodation and convergence systems,” Rodney said. “Over time, that sustained effort can lead to fatigue, discomfort and reduced visual efficiency.”
Children May Be More Vulnerable
While adults frequently report digital fatigue, practitioners are observing similar complaints in younger patients.
Jacquie Gattegno, principal senior optometrist at Eyes InDesign Smart Vision Optometry Bondi and an experienced Behavioural Optometrist and Orthokeratologist, says children often do not recognise the source of their discomfort.
“A child might describe sore eyes, headaches or simply say they’re tired,” Gattegno said. “Parents may assume it’s behavioural or related to attention, but visual strain is frequently a contributing factor.”
Unlike adults, children may hold devices significantly closer to their eyes and may not instinctively take breaks. Developing visual systems are more susceptible to sustained near demand, particularly if underlying focusing or eye coordination issues are present.
The Myopia Connection
Increased screen time has also been associated with rising rates of myopia. While research continues to examine the precise mechanisms, prolonged near work combined with reduced outdoor activity is widely considered a contributing factor.
Rodney explained that near demand alone does not cause myopia, but it can accelerate progression in susceptible children.
“Myopia development is multifactorial,” he said. “Genetics play a role, but environmental factors such as sustained near work and limited outdoor exposure can influence the rate of progression.”

Blue Light and Sleep Disruption
Beyond visual fatigue, evening screen exposure may also disrupt sleep cycles. Blue light emitted from digital devices can interfere with melatonin production, delaying sleep onset and reducing overall sleep quality.
Rodney noted that poor sleep can further compound visual stress.
“When children are fatigued, their visual endurance decreases,” he said. “Sleep hygiene and screen timing are just as important as optical solutions.”
While blue light filtering lenses may provide comfort in certain circumstances, practitioners emphasise that behavioural strategies remain essential.
Practical Steps for Families
Optometrists recommend simple strategies to reduce digital strain:
- Improve on the 20-20-20 rule: every 20 minutes, look 20 feet away for 20 seconds. the improvement is that every 30 minutes we need a complete 10 minute break from near viewing to release the visual stress.
- Maintain appropriate screen distance, ideally at least 40 centimetres and computers at amr’s length
- Position screens slightly below eye level.
- Ensure adequate room lighting to reduce glare.
- Encourage regular blinking to support tear film stability.
- Maintain a minimum of two hours day light exposure outdoors every single day.
Gattegno said small adjustments can significantly reduce symptoms.
“Simple habit changes often produce noticeable improvements,” she said. “We encourage families to create structured screen breaks, especially during homework sessions.”
Behavioural Optometry and Visual Efficiency
In some cases, Digital Eye Strain may reveal underlying visual efficiency issues such as poor eye teaming, tracking or focusing stamina.
Behavioural optometry assessments evaluate how effectively the eyes work together and process visual information, not just clarity of sight.
“If a child has subtle binocular vision difficulties, extended screen time amplifies those weaknesses,” Gattegno said. “Vision therapy can strengthen these systems and improve comfort.”
Rodney added that early identification can prevent long-term strain patterns.
“When visual systems are balanced and efficient, children can sustain near tasks with less fatigue,” he said.
When to Seek Professional Advice
Persistent headaches, avoidance of reading, frequent eye rubbing or declining school performance may warrant a comprehensive eye examination.
Rodney emphasised that annual reviews are important, particularly for children engaged in heavy academic workloads.
“Vision changes can occur gradually,” he said. “Routine assessments allow us to detect small shifts before they become significant problems.”
For children already experiencing myopia progression, management strategies such as Orthokeratology may also be discussed.

Gattegno believes education remains key.
“Technology isn’t the enemy,” she said. “It’s about balance, awareness and ensuring the visual system is supported.”
A Balanced Approach to Modern Life
As digital devices remain central to education and social interaction, eye care professionals are encouraging families to adopt practical preventative habits rather than eliminate screens entirely.
Rodney said proactive care offers reassurance.
“With appropriate monitoring, lifestyle adjustments and, where necessary, myopia management strategies, we can support children’s visual health in a digital world,” he said.
Gattegno agreed that early conversations can make a meaningful difference.
“Parents shouldn’t wait until symptoms are severe,” she said. “Addressing visual comfort early can improve both wellbeing and academic performance.”
