The Digital Era and Its Impact on Young Eyes
In today’s world, it’s nearly impossible to separate children from digital screens. Whether it’s online learning, mobile games, YouTube videos, or social media, kids are spending more time in front of screens than ever before.
While technology has made education and entertainment easily accessible, the growing screen time among children is silently affecting their eye health and overall well-being.
Doctors across India, including Dr. Deepankur Mahajan, one of the leading eye specialists in Delhi, are witnessing a sharp rise in digital eye strain, myopia (short-sightedness), and dry eyes in children.
Understanding the Problem: Why Kids’ Eyes Are at Risk
Children’s eyes are still developing, making them more vulnerable to the effects of prolonged screen exposure.
When kids focus on a screen — whether it’s a tablet, phone, or computer — they blink less often, and their eyes are forced to maintain close focus for long periods. This leads to eye strain, dryness, and fatigue.
Moreover, the blue light emitted from digital devices penetrates deep into the retina and may contribute to retinal stress and disrupted sleep cycles.
Common Eye Problems Caused by Excessive Screen Time:
- Digital Eye Strain (Computer Vision Syndrome)
- Dry Eyes
- Eye Fatigue and Headaches
- Myopia (Nearsightedness)
- Blurry Vision or Difficulty Focusing
- Sleep Disturbances due to blue light exposure
How Much Screen Time Is Too Much?
According to pediatric eye health experts, including Dr. Deepankur Mahajan from Mahajan Eye Centre, the ideal screen time for children depends on their age:
| Age Group | Recommended Daily Screen Time |
|---|---|
| Below 2 years | No screen exposure (except video calls) |
| 2–5 years | Up to 1 hour/day of high-quality, supervised screen time |
| 6–12 years | Maximum 2 hours/day (excluding schoolwork) |
| 13–18 years | Up to 3 hours/day (with regular breaks) |
Beyond these limits, children are more likely to experience eye strain, poor sleep, and attention issues.
The Science Behind Screen-Induced Eye Strain
When your child stares at a screen for long durations, their eyes continuously adjust focus and movement, leading to ocular fatigue.
Key Factors That Cause Digital Eye Strain in Kids:
- Blue Light Exposure: High-energy visible (HEV) light from screens disrupts the retina and circadian rhythm.
- Reduced Blinking: Kids blink up to 60% less while watching screens, leading to dryness.
- Close Viewing Distance: Children often hold screens too close (within 25–30 cm).
- Poor Posture & Lighting: Bright screens in dark rooms strain the eye muscles.
Signs That Your Child May Be Experiencing Digital Eye Strain
Parents must be alert to the subtle signs of eye strain or visual stress caused by screens.
Common Symptoms Include:
- Frequent rubbing of eyes
- Complaints of burning or itching
- Watering or redness
- Squinting or leaning forward to see better
- Blurry or double vision
- Headaches or neck pain after screen use
- Difficulty focusing on distant objects
- Poor attention span during reading or homework
If your child shows one or more of these symptoms, it’s time for a comprehensive eye check-up at a reputed clinic like Mahajan Eye Centre, Delhi.

The Link Between Screen Time and Myopia (Nearsightedness)
One of the most concerning outcomes of increased screen exposure in kids is the rising rate of myopia.
Research shows that children who spend more time indoors on digital devices and less time outdoors are more likely to develop myopia (short-sightedness) at a young age.
Why This Happens:
- Prolonged close-up focus causes the eyeball to elongate over time.
- Reduced exposure to natural daylight affects the development of healthy vision.
The Solution:
Encourage your child to spend at least 1–2 hours outdoors every day — even simple activities like walking, cycling, or playing outside can help prevent or slow down myopia progression.
How to Protect Your Child’s Eyes from Screen Damage
Here are practical, doctor-recommended tips to reduce the impact of screens on your child’s eyes:
1. Follow the 20-20-20 Rule
After every 20 minutes of screen time, encourage your child to look at something 20 feet away for 20 seconds. This simple rule reduces eye fatigue.
2. Maintain Proper Screen Distance
Ensure the device is at least an arm’s length (18–24 inches) away from the eyes.
3. Encourage Outdoor Activities
Playing outside not only improves eye health but also promotes overall physical and mental well-being.
4. Adjust Screen Brightness
Set screen brightness similar to surrounding light — neither too bright nor too dim.
5. Use Blue Light Filters
Install blue light filter apps or lenses to reduce exposure. Many modern devices have “Night Mode” or “Eye Comfort Mode.
6. Limit Screen Time Before Bed
Avoid screens 1–2 hours before sleep, as blue light suppresses melatonin and disrupts sleep cycles.
7. Regular Eye Check-Ups
Schedule annual eye exams at Mahajan Eye Centre to detect and manage refractive changes or early eye strain symptoms.
Role of Parents in Maintaining Healthy Screen Habits
Parents play a critical role in shaping how children use technology. Rather than completely restricting screen use, it’s about teaching balance and healthy digital habits
Parenting Tips:
- Be a role model — reduce your own screen time around children.
- Set tech-free zones, like the dining area or bedroom.
- Encourage screen-free hobbies — reading, drawing, music, or outdoor games.
- Involve kids in non-digital learning activities to reduce dependency on devices.
Holistic Eye Health: Nutrition & Lifestyle Tips
A healthy diet also plays a major role in maintaining strong vision in children.
Foods That Improve Eye Health:
- Carrots & Spinach: Rich in Vitamin A for retinal health.
- Fish (Salmon, Tuna): Contains Omega-3 fatty acids for eye lubrication.
- Citrus Fruits: Packed with Vitamin C for tissue repair.
- Eggs: Contain lutein and zeaxanthin, which protect against blue light.
- Nuts & Seeds: Provide Vitamin E and antioxidants.
Encourage regular sleep, hydration, and outdoor activity — these habits go a long way in maintaining healthy vision.
