PTC Web Desk: While screens have become an integral part of children's lives, it is important to be mindful of their potential impact on eye health. By promoting healthy screen habits and encouraging a balanced lifestyle, parents and caregivers can help mitigate the screen effect on kids' eyes. 

So, let us discuss the side effects of screen time on kids' eyes and some practical tips for promoting healthy habits.

Children now spend a significant amount of time engaged with screens, including smartphones, tablets, computers, and televisions. Prolonged exposure to screens can lead to various eye-related issues, collectively known as Computer Vision Syndrome (CVS) or Digital Eye Strain.


eye strain, dryness, redness, blurred vision, headaches, and neck or shoulder discomfort.

Factors Contributing to eye strain

Blue Light: Screens emit blue light, which can penetrate the eye and potentially cause damage to the retina. While research on the long-term effects is ongoing, it is advisable to take precautions to minimize exposure, especially close to bedtime.

Increased Blinking Rate: Children often blink less frequently when engaged with screens, leading to dry and irritated eyes. Insufficient blinking reduces the spread of tears and can cause discomfort.

Viewing Distance and Angle: Children may hold screens too close to their eyes or at awkward angles, resulting in additional strain on the eye muscles.

Promoting Healthy Screen Habits

Parents and caregivers can play a crucial role in safeguarding their children's eye health. Some of the practical tips are as below:

Limit Screen Time: Establish clear guidelines for screen time duration appropriate for your child's age. Encourage breaks and engage in alternate activities such as outdoor play, reading, or creative pursuits.

Follow the 20-20-20 Rule: Encourage your child to take a 20-second break every 20 minutes, focusing on an object 20 feet away. This simple practice helps relax eye muscles and reduce strain.

Optimal Viewing Conditions: Ensure adequate lighting in the room to reduce screen glare and avoid using screens in dark environments. Adjust screen brightness and contrast settings to a comfortable level.

Maintain Proper Posture: Encourage your child to maintain a good posture while using screens. The screen should be at eye level, and they should sit at a reasonable distance to minimise strain on their eyes and neck.

Encourage Outdoor Time: Regular outdoor activities provide a much-needed break from screen exposure and help promote overall eye health.

Model Healthy Habits: Set a positive example by practicing healthy screen habits yourself. Children are more likely to adopt these habits if they see their parents and caregivers doing the same.
