Digital Eye Strain (DES), often overlooked in conversations about screen time, has become an increasingly common issue as more people spend prolonged hours staring at digital devices. Recently published studies and surveys highlight the growing prevalence of DES and its sharp rise during the COVID-19 pandemic, emphasizing the urgent need for awareness and preventive measures.
TL;DR
Digital Eye Strain (DES) is now a widespread public health concern. It intensified during the COVID-19 pandemic and continues to remain high due to remote work, online learning, and heavy daily screen exposure.
Key Statistics:
- 50%+ of computer users experienced DES symptoms even before the pandemic (BMJ, 2018).
- 93.6% reported increased screen time during lockdowns (Springer, 2024).
- 56.5% reported more frequent or intense DES symptoms during the pandemic (Springer, 2024).
- 80%+ of Gen Z and Millennials experience DES compared to ~50% of those over 50 (CooperVision, 2023).
- Remote work rose to 3.8 days/month in 2023, up from 2.4 in 2019 (Gallup, 2023).
Alarming Statistics on Digital Eye Strain
Pre-Pandemic Prevalence: A 2018 review in BMJ Open Ophthalmology indicated that digital eye strain (DES), also known as computer vision syndrome, affects over 50% of computer users (BMJ Open Ophthalmology, 2018).
Pandemic Spike: During the COVID-19 lockdowns, screen time surged due to remote work and online learning. A study found that 93.6% of participants increased their screen time during the lockdown, with 56.5% reporting heightened frequency and intensity of DES symptoms (Springer, 2024).
Generational Divide: Younger individuals, particularly Gen Z and Millennials, are disproportionately affected. Over 80% of respondents aged 18–34 report symptoms of DES compared to about 50% of those over 50 (CooperVision, 2023).

Addressing the Silent Epidemic
The dramatic rise in DES, especially during the pandemic, serves as a wake-up call to prioritize eye health in the digital era. Addressing DES requires proactive measures, including improving workplace ergonomics, reducing unnecessary screen time, and raising awareness about the long-term consequences of untreated eye strain.
Small lifestyle changes, such as ensuring proper screen positioning, staying hydrated, and seeking specialized solutions like DES-specific eyewear or contact lenses, can make a significant difference. Additionally, promoting outdoor activities and regular eye exams can help mitigate the risks associated with prolonged digital device usage.
The Health Risks of Ignoring DES
Vision Decline: Prolonged screen use can lead to accommodative dysfunction, a condition where the eyes struggle to shift focus between near and distant objects, often resulting in blurred vision (American Optometric Association, n.d.).
Disrupted Sleep Patterns: Blue light exposure from screens, especially during the evening, suppresses melatonin—a hormone critical for regulating sleep—leading to poor sleep quality and increased fatigue (Harvard Health, 2018).
Productivity Loss: Persistent symptoms of DES, such as headaches and visual discomfort, can impair work efficiency and overall productivity (AP News, 2023).
Why DES is Increasing
Extended Screen Use: The average person now spends more time on digital devices than sleeping, contributing significantly to eye strain.
Pandemic Lifestyle Changes: Remote work and online learning caused a sharp increase in daily screen time, with many individuals exceeding 10 hours of screen use per day. Poor workstation setups during this period also highlighted the importance of ergonomic practices in preventing digital eye strain and fatigue.
Reduced Outdoor Activity: Lockdowns led to a significant decline in outdoor exposure, which is crucial for reducing myopia progression and maintaining overall eye health.
Increased Use of Smaller Screens: Frequent use of smartphones and tablets, which require closer focus, leads to more intense strain on the eyes.
Final Thoughts
Digital Eye Strain is no longer just a minor inconvenience; it’s a silent epidemic impacting millions worldwide. With screen time only set to increase, addressing DES requires a multi-faceted approach that includes both individual responsibility and broader public health initiatives. By taking steps now, we can safeguard our vision and improve our overall quality of life in a screen-dominated world.

Frequently Asked Questions About Screen Time
How do I check screen time on iPhone?
Go to Settings → Screen Time → See All Activity. Here you can view daily and weekly reports of your usage.
Why is screen time bad for kids?
Too much screen time can cause digital eye strain, interfere with sleep cycles, and reduce attention span. Pediatricians recommend setting daily limits based on age.
What are screen time recommendations by age?
The American Academy of Pediatrics suggests children aged 2–5 should have no more than 1 hour of quality screen time daily. Older kids and teens should have consistent limits to prioritize sleep, study, and physical activity.
Do glasses help with screen time eye strain?
Blue light filtering and anti-reflective glasses can reduce glare and eye fatigue. However, regular breaks and good ergonomics remain the most effective strategies.
