Prolonged use of screens can cause digital eye strain (also called computer vision syndrome) in children.
Symptoms include dry eyes, headaches, blurry vision, and diAculty focusing. Children’s eyes are still developing, making them more vulnerable to strain caused by close-up screen use.
2. Blue Light Exposure and Its Effects
Digital devices emit blue light, which can disrupt sleep patterns by suppressing melatonin production. Excessive exposure may also lead to fatigue and discomfort. While no definitive evidence links blue light to long-term damage, managing exposure is critical for children.
3. Importance of the 20-20-20 Rule
Teach children to follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This simple habit reduces eye strain and encourages regular eye breaks.
4. Setting Up an Eye-Friendly Screen Environment
Position screens at arm’s length and slightly below eye level. Adjust screen brightness to match the surrounding light, and use anti-glare screens. Ensure proper lighting in the room to reduce contrast between the screen and the background.
5. Encouraging Healthy Screen Time Habits
Limit recreational screen time to 1-2 hours daily for children. Encourage outdoor activities to promote overall eye health and reduce myopia progression. Teach children to blink more often when using screens to prevent dry eyes.
Additional Tips for Parents
Schedule regular eye exams to detect early signs of digital eye strain or refractive errors. Invest in protective eyewear, like blue light-blocking glasses, if recommended by your eye doctor.
Create tech-free zones at home, like during meals or before bedtime, to foster healthy screen habits.
