For decades, office ergonomics focused primarily on musculoskeletal concerns such as neck pain, back discomfort, and repetitive strain injuries. This will remain so while people are the intelligence using computers. But in 2026, another workplace health issue is rapidly demanding attention.
Digital Eye Strain (DES), also referred to as Computer Vision Syndrome (CVS), is a preventable condition which often results from chronic unmanaged use of digital devices such as computers, smartphones, and tablets due to the repetitive need for viewing text and images often at very small scale.
Last year, we brought light to a 2025 study finding DES Prevalence has ticked up from 66% to 69%.
Now today, as hybrid work, AI-assisted workflows, and multi-screen environments continue expanding, workers are spending unprecedented amounts of time visually engaged with digital devices. Employers are increasingly finding that eye strain is no longer a secondary complaint – it is becoming one of the defining occupational health concerns of the modern office.
DES is seldom visible since employees almost always visit their eye doctor for treatment of symptoms, not knowing they should instead consult with an ergonomist and mitigate root causes to prevent the symptoms in the first place.
Employers can identify it, however, through analyzing their healthcare spend records – if they know where to look. A simpler and easy method is leveraging employee self-assessments including questions identifying DES symptoms.
Hundreds of studies in over 20 countries have collectively shown that more than two of every three knowledge workers have some degree of DES.
For employers, the impact of DES extends beyond individual health concerns and affects productivity, healthcare spend, musculoskeletal disorder incidence, cybersecurity and overall employee well-being.
In this article, we’ll review expert analysis of 103 cross-sectional studies with 66,577 participants and explore the implications of DES for employers, citing recent studies and providing a basis of understanding its impacts on employees and employers.
“Viewing a computer or digital screen often makes your eye muscles work significantly harder. As a result, the unique characteristics and high visual demands of computer and digital screen viewing make many individuals susceptible to the development of vision-related symptoms.” Seasoned safety professionals understand how, quite often, many people will tilt their heads at odd angles or they bend toward the screen in order to see it clearly. These prolonged awkward postures often result in pain in the neck, shoulder or back.
Common DES Symptoms
- Eye strain and discomfort
- Dry eyes or excessive tearing
- Blurred or double vision
- Headaches, migraines
- Neck, back and shoulder pain
Your intrepid author came across an illuminating study published in Nature: “Prevalence of Computer Vision Syndrome: A Systematic Review and Meta-Analysis (read)“. More than a one-off individual study, this was a painstaking comprehensive meta-analysis reviewing the most recent 745 research studies on the topic from 20 countries. A total of 103 cross-sectional studies with 66,577 participants were included.
From this study “The pooled prevalence of computer vision syndrome was determined to be around 66%“. Generally, two of every three of your coworkers has some degree of Computer Vision Syndrome. The study continued “Although computer vision syndromes are becoming a major public health concern, less emphasis is given to them, particularly in developing countries.“
A newer study published in 2025, “Computer Vision Syndrome: A Comprehensive Literature Review (read)“, updated prevalence to be around 69%.
Some helpful framing of the issue from the study published in Nature includes:
- The massive growth of digital devices has become an integral part of daily life, and millions of individuals of all ages are at risk of CVS.
- In developed nations, engagement with digital devices has increased substantially in recent years across all age groups.
- Digital device use has increased in developing countries, resulting in a high burden of DES due to low accessibility, low utilization of personal protective equipment, and limited break time while using electronic devices.
- DES is a major public health problem leading to occupational hazard, an increased error rate, impaired visual abilities, reduced productivity, and low job satisfaction.
- A review of the literature showed that factors associated with DES can be classified as personal factors, which include poor sitting position, inappropriate eye-to-screen distance, insufficient working procedures, improper viewing angle and distances, age, medical diseases, and long duration of computer usage.
- The environment and computer factors such as improper workstations, poor lighting, contrast, and resolution rooms, slow refresh rate, glare of the display, excessive screen brightness, and imbalance of light between the computer screen and surrounding working room.
- DES has an effect on reduced productivity and visual and musculoskeletal impairment and a negative impact on cardiac rhythms and sleep patterns.
Why Digital Eye Strain Is Receiving More Attention in 2026
1. Continuous Screen Exposure Is Increasing
One of the biggest drivers of Digital Eye Strain in 2026 is simply exposure duration. Hybrid and knowledge workers now spend much of their waking day visually engaged with screens. Unlike earlier office environments where tasks naturally varied, digital work has become increasingly continuous.
Employees often attend virtual meetings, monitor messaging platforms, review AI-generated content, switch between multiple windows, and remain visually engaged for hours with few natural breaks.
2. AI Workflows May Be Intensifying Visual Fatigue
The rapid integration of generative AI into office work is changing visual demands in subtle but important ways. Emerging workplace studies suggest that AI-assisted workflows can accelerate information processing, increase reading and editing volume, reduce idle cognitive pauses, and encourage longer periods of uninterrupted screen fixation.
Ergonomists are now discussing what some researchers describe as “AI acceleration fatigue” – a combination of cognitive overload and sustained visual concentration. Although research in this area is still developing, many experts believe AI-heavy work environments may increase Digital Eye Strain risk unless organizations intentionally build in movement and recovery opportunities.
3. Digital Eye Strain Has Been Identified as a Cybersecurity Risk
Human factors and cybersecurity research has confirmed the connection between visual fatigue and employee error.
Cybersecurity incidents frequently depend on human behavior: clicking phishing links, overlooking suspicious prompts, misreading URLs, approving incorrect permissions, or failing to recognize anomalies.
Digital Eye Strain contributes to these risks through increased attention fatigue, visual processing errors, cognitive overload, and reduced vigilance during prolonged screen work.
AI-assisted workflows can intensify this problem further. Employees now process larger amounts of digital information, often across multiple monitors and communication platforms simultaneously. As fatigue accumulates, workers may become more likely to skim content, overlook warning signs, or rely on automatic behavior rather than careful verification.
For ergonomists, this represents an important shift: Digital Eye Strain is no longer simply a comfort issue. In highly digital workplaces, visual fatigue may also influence operational performance, decision-making quality, and organizational resilience.
4. Multi-Screen Workstations Create New Challenges
Another current concern is the widespread use of ultra-wide monitors, dual and triple-screen setups, and large-format displays.
While these technologies can improve productivity, they also increase visual scanning demands, accommodative stress, head and neck rotation, and sustained visual attention.
In many workplaces, ergonomists are finding that visual ergonomics has not kept pace with display technology adoption. Simply adding more screen space does not create a healthier workstation.
5. Younger Workers Are Reporting Higher Symptom Levels
Recent surveys and occupational health studies suggest younger workers experience particularly high rates of digital eye strain.
Researchers believe several factors contribute including near-continuous device exposure, smartphone dependency outside work, reduced visual recovery time, and prolonged near-focus activity across both professional and personal settings.
Some experts now describe this phenomenon as cumulative visual load – the total visual demand placed on workers throughout the day rather than during work hours alone.
6. The Link Between Eye Strain and Musculoskeletal Pain
An important past finding is the strong relationship between visual fatigue and musculoskeletal discomfort.
Workers experiencing eye strain frequently also report neck tension, shoulder discomfort, forward head posture, and upper back pain. This occurs partly because visual discomfort often changes posture behavior. Employees often lean forward, crane their neck, squint, or adopt awkward viewing positions when struggling to see screens comfortably.
Visual ergonomics and physical ergonomics have become interconnected.
Scope and Depth
While the list of DES studies is long, another recent article on the topic from The American Optometric Association (AOA): Computer Vision Syndrome (read) confirms the scope and depth of the issue for knowledge workers. Guidance from the article includes:
- Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods.
- The level of discomfort appears to increase with the amount of digital screen use.
- The average American worker spends seven hours a day on the computer either in the office or working from home.
- Viewing a computer or digital screen is different than reading a printed page. Often the letters on the computer or handheld device are not as precise or sharply defined, the level of contrast of the letters to the background is reduced, and the presence of glare and reflections on the screen may make viewing difficult.
- At greatest risk for developing CVS are those persons who spend two or more continuous hours at a computer or using a digital screen device every day.
- Some individuals may experience continued reduced visual abilities, such as blurred distance vision, even after stopping work at a computer.
- Important factors in preventing or reducing the symptoms of CVS have to do with the computer and how it is used.
- This includes lighting conditions, chair comfort, location of reference materials, the position of the monitor, and the use of rest breaks.
DES Is Known To Contribute To Musculoskeletal Disorders
Further, from the AOA article, “Some people tilt their heads at odd angles because their glasses aren’t designed for looking at a computer or they bend toward the screen in order to see it clearly. Their postures can result in muscle spasms or pain in the neck, shoulder or back.“
This is consistent with other studies shared in previous articles where it’s been confirmed how people often adjust their posture to compensate for visual challenges encountered while working at their computers.
You probably already know that prolonged awkward and static postures are very highly correlated with increased risk and reported injury.
DES Mitigation, Best Practice Behaviors
In the AOA article and in most other articles from experts in the field, you’ll find Mitigation Strategies include:
- Rest breaks. To prevent eyestrain, try to rest eyes when using the computer for long periods. Resting the eyes for 15 minutes after two hours of continuous computer use.
- Eye exercises. For every 20 minutes of computer viewing, look into the distance for 20 seconds to allow the eyes a chance to refocus.
- Lighting. Position the computer screen to avoid glare, particularly from overhead lighting or windows. Use blinds or drapes on windows and replace the light bulbs in desk lamps with bulbs of lower wattage.
- Seating position. Chairs should be comfortably padded and conform to the body. Chair height should be adjusted so the feet rest flat on the floor. Arms should be adjusted to provide support while typing and wrists shouldn't rest on the keyboard when typing.
- Location of the computer screen. Most people find it more comfortable to view a computer when the eyes are looking downward. Optimally, the computer screen should be 15 to 20 degrees below eye level (about 4 or 5 inches) as measured from the center of the screen and 20 to 28 inches from the eyes.
- Blinking. To minimize the chances of developing dry eye when using a computer, try to blink frequently. Blinking keeps the front surface of the eye moist.
- Reference materials. These materials should be located above the keyboard and below the monitor. If this is not possible, a document holder can be used beside the monitor. The goal is to position the documents, so the head does not need to be repositioned from the document to the screen.
- Anti-glare screens. If there is no way to minimize glare from light sources, consider using a screen glare filter. These filters decrease the amount of light reflected from the screen.
The risk mitigation list above is practical and doesn’t involve large expense. Beyond the basic workstation improvements, you probably already know that the best defense against threats to knowledge worker wellbeing is helping them learn automatic healthful behaviors.
The only remaining question involves how do you help the people you’re responsible for to learn to make those behaviors into automatic habits to improve their wellbeing.
Science and history have shown that you can improve these safety behaviors through a point-of-use operant conditioning positive reinforcement tool being used.
