The digital age has transformed the way children learn, play, and interact. While technology offers countless educational and recreational benefits, it also comes with challenges. One of the most significant concerns is the impact of excessive screen time on children’s eye health. Prolonged exposure to screens can lead to discomfort, eye strain, and even long-term issues like progressive myopia and binocular vision disorders, if not managed effectively. At Shekar Eye Hospital, we aim to educate parents and caregivers on how to set healthy limits and protect children’s vision.

Understanding the Risks of Excessive Screen Time

1. Digital Eye Strain

Also known as Computer Vision Syndrome, digital eye strain results from prolonged screen exposure. Symptoms include dry eyes, headaches, blurred vision, and difficulty focusing. Children often don’t realise they’re experiencing discomfort, which makes early intervention crucial.

2. Myopia (Nearsightedness)
The global rise in myopia, particularly in children, is attributed to excessive screen use and limited outdoor activities. When children focus on near objects for extended periods, it can strain the eyes, causing the eyeball to elongate, which in turn affects how light is focused onto the retina and leads to blurred vision at a distance.

3. Sleep Disturbances

The blue light emitted by screens can disrupt melatonin production, a hormone that regulates sleep. Poor sleep not only affects overall health but also hinders the eyes’ ability to rest and recover.

4. Reduced Outdoor Time

Screen time often replaces outdoor activities, depriving children of exposure to natural light. Sunlight is vital for healthy eye development and reduces the risk of myopia. 

Setting Healthy Limits for Screen Time

1. Follow the 20-20-20 Rule

Encourage children to take a 20-second break every 20 minutes and look at something 20 feet away. This simple rule helps reduce digital eye strain and promotes better focus.

2. Limit Screen Usage

The World Health Organization (WHO) recommends no screen time for children under two and a maximum of one hour daily for children aged 2-5. For older kids, ensure screens are used in moderation and primarily for educational purposes.

3. Create Tech-Free Zones

Establish areas in your home where screens are not allowed, such as the dining table and bedrooms. This helps children engage in family activities and ensures screens don’t disrupt sleep schedules.

4. Encourage Outdoor Activities

Balance screen time with outdoor play. Natural light exposure has been shown to reduce the risk of myopia and improve overall well-being.

5. Use Screen Filters and Adjust Settings

Equip devices with blue light filters and reduce screen brightness. Position screens at eye level and maintain an optimal viewing distance of 18-24 inches.

Role of Parents and Caregivers

Parents play a critical role in modeling healthy screen habits. Here are some tips to guide your children:

Set a Good Example: Children mimic adult behaviour. Limit your own screen time and prioritise face-to-face interactions.

Communicate the Why: Explain to children why limiting screen time is essential for their eye health and overall development.

Use Educational Apps and Content: Opt for high-quality, educational apps that encourage learning and creativity.

Monitor Usage: Keep track of the time your child spends on devices and the type of content they consume.

Recognising Signs of Eye Strain in Kids

Children may not always articulate discomfort, so it’s important to watch for signs such as:

• Frequent rubbing of eyes
• Frequent blinking 
• Complaints of headaches
• Squinting or sitting too close to screens
• Redness or dryness of eyes
• Difficulty focusing on distant objects

If you notice any of these symptoms, consult an eye care professional promptly.

Eye-Friendly Habits to Promote

Blink Often: Teach children to blink consciously while using screens to keep their eyes moist.

Hydrate: Ensure they drink plenty of water to maintain good eye health.

Balanced Diet: Incorporate eye-friendly foods rich in vitamins A, C, and E, such as carrots, spinach, and citrus fruits.

When to Visit an Eye Specialist

Regular eye check-ups are essential for children, even if they don’t complain of discomfort. Early detection of issues like myopia can prevent complications later.
