As screen time increases and air pollution becomes more prevalent, children's eye health is at greater risk than ever before. Two major factors contributing to this growing concern are blue light exposure from digital devices and the harmful effects of air pollution. With children spending more time on screens for both learning and entertainment, and air quality deteriorating in metro cities, parents need to be aware of the negative effects these factors have on young eyes.
Dr Neeraj Sanduja, MBBS, MS, an Ophthalmologist and Eye Surgeon at Viaan Eye and Retina Centre, shares strategies to protect children's eye health. The Impact of Blue Light on Children’s Eyes Blue light, a part of high-energy visible light, is emitted from digital screens such as smartphones, tablets, computers, and televisions. While blue light is naturally present in sunlight and plays a role in regulating our sleep-wake cycle, overexposure to blue light from screens can be harmful, particularly for children.
“Children are more vulnerable to blue light exposure because their retinas are thinner compared to adults,” shares Dr Sanduja. "This makes them more susceptible to damage from prolonged screen time." Research suggests that blue light can cause digital eye strain, with symptoms like blurry vision, dry eyes, headaches, and difficulty focusing.
“Children often don't recognize or express these symptoms,” says Dr Sanduja. "This can negatively impact their academic performance and overall well-b.
