In today’s tech-driven world, screen time is an unavoidable part of life—especially for teenagers. Whether it's for schoolwork, socializing, gaming, or watching videos, teens spend hours each day in front of screens. While this digital immersion has its benefits, it also comes with health concerns. One of the most pressing—and often overlooked—is digitale ye strain (DES).

‍

What Is Digital Eye Strain?

Digital Eye Strain, also known as computer vision syndrome, refers to a group of eye and vision-related problems that result from prolonged screen use. Common symptoms include:

• Blurred vision
• Dry eyes
• Eye fatigue
• Headaches
• Neck and shoulder pain

Teenagers are particularly vulnerable because of their high screen exposure and the way they use devices—often up close and for long, uninterrupted periods.

Even more concerning, children and teens often don’t recognize or understand these symptoms. A headache, blurry vision, or tired eyes may seem like a normal part of their day. As a result, they often ignore the early warning signs, which only allows the strain to intensify over time. Left unchecked, this can evolve into chronic discomfort, reduced attention span, and even behavioral changes.

How Much Screen Time Is Too Much?

According to the American Academy of Pediatrics, children aged 13–18 spend an average of 7–9 hours per day in front of screens. This includes time spent on phones, tablets, computers, and TVs. During theCOVID-19 pandemic, this number spiked even higher due to remote learning and limited in-person social activities.

Recent studies show that using screens for more than 2hours a day—especially without breaks—increases the risk of digital eyestrain significantly.

What Does the Research Say?

Several recent studies (2020–2025) have highlighted the growing concern of DES among adolescents:

-A 2024 study in PLOS ONE found that 63.7% of adolescents reported symptoms of DES, and many also experienced poor sleep quality.

-A systematic review published in Preventive Medicine in 2023 emphasized the link between prolonged digital device use and worsening visual health among youth.

-Another study from Hong Kong in 2023 showed that teens using smartphones for more than 4 hours a day had significantly higher rates of eye strain and fatigue.

Importantly, researchers are also noting a behavioral impact associated with DES. Teens who experience regular eye strain may also show increased irritability, difficulty focusing, withdrawal, or even signs of aggression. The discomfort and fatigue caused by strained eyes can easily spill over into mood and behavior—affecting academic performance, social interactions, and family dynamics.

What Parents Can Do

While it's impossible (and often unrealistic) to eliminate screen time altogether, there are practical ways to reduce the risk of digital eye strain:

-Encourage the 20-20-20 Rule.
Every 20 minutes, look at something 20 feet away for at least 20 seconds. This helps reduce eye fatigue.

-Set Screen Time Limits.
Use device settings or parental controls to limit non-essential screen time—especially at night.

-Ensure Proper Lighting.
Avoid using screens in dark rooms or direct sunlight. Soft, ambient lighting reduces glare and helps eye comfort.

-Adjust Display Settings.
Encourage teens to increase text size, lower brightness, and use blue light filters, especially in the evening.

-Promote Regular Breaks.
Make sure teens take short breaks between study or gaming sessions to rest their eyes and stretch their body.

-Talk  Openly About Symptoms.
Since children often don’t realize when their eyes are tired or strained, ask them how their eyes feel during screen time. Help them recognize signs of discomfort and make it normal to take breaks or ask for help.

-Watch for Mood and Behavioural Changes.
If your child is suddenly irritable, distracted, or disengaged, consider whether screen-related strain might be a factor. Addressing DES early can ease both physical and emotional stress.

-Schedule Eye Exams.
Regular check-ups with an eye doctor can help detect early signs of strain     and recommend corrective measures if needed.
