How Digital Devices & Blue Light Affect Children’s Eyes

Boys Gaming Blue Light

Children spend more time in front of computer screens than ever in today's digital age. From tablets and smartphones to computers and televisions, digital devices have become integral to their daily lives.

Although these devices offer educational benefits and entertainment, they also emit blue light, which can have implications for children's eye health in the long term. As a parent, it is important to understand the effects of blue light exposure and how to protect your child's eyes.

In this blog, we will talk about blue light, how it affects children's eyes, and ways to protect their vision with blue light glasses from Boise Mountain Eyecare.

What is Blue Light?

Blue light is a visible light within the spectrum with a short wavelength and high energy. It is found in natural sunlight and can be beneficial in small doses for regulating the body's sleep-wake cycle and boosting alertness. However, excessive exposure from artificial sources like digital devices, LED lights, and other forms of artificial light can be quite harmful, resulting in poor sleeping patterns and eye strain.

The Impact of Blue Light on Children's Eyes

Children's eyes are more susceptible to blue light exposure for several reasons:

Increased Screen Time: Children today spend significant time on digital devices for educational and recreational purposes. This prolonged screen exposure increases their risk of digital eye strain, myopia, dry eyes, and other related issues.

Developing Eyes: Children's eyes are still developing, and their lenses are more transparent than those of adults. This allows more blue light to penetrate and reach the retina.

Close-Up Viewing: Children often hold devices closer to their eyes than adults. Doing so intensifies blue light exposure and contributes to eye fatigue and myopia.

Potential Risks of Blue Light Exposure

Excessive blue light exposure can lead to several eye-related issues in children:

Digital Eye Strain: Also known as computer vision syndrome, digital eye strain results from prolonged use of digital screens. Symptoms include dry eyes, headaches, blurred vision, and difficulty focusing.

Disrupted Sleep Patterns: Blue light exposure, especially before bedtime, can interfere with the production of melatonin, a hormone that regulates sleep. This disruption can lead to difficulty falling asleep and altered circadian rhythms.

Potential Long-Term Damage: Some studies suggest long-term exposure to harmful blue light may contribute to retinal damage. It might also increase the risk of age-related macular degeneration (AMD) later in life.

How to Protect Your Child's Eyes from Blue Light Exposure

As a parent, there are several steps you can take to minimize your child's blue light exposure and protect their eyes:

Limit Screen Time: Regulate how much your child spends on digital devices. Encourage them to follow the 20-20-20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away. This helps reduce eye fatigue.

Adjust Screen Settings: Reduce the brightness of screens and enable blue light filters or "night mode" on devices. This reduces the amount of blue light emitted by electronic devices.

Use Protective Eyewear: Consider investing in computer or blue light-blocking glasses for your child, especially if they spend a lot of time on screens. These glasses can filter out blue light and reduce digital eye strain.

Promote Good Habits: Encourage your child to maintain a proper distance from screens and to use devices in well-lit environments.

Create a Digital Curfew: Limit screen use the hour before bedtime to prevent sleep disturbances caused by blue light exposure.

Regular Eye Exams: Ensure your child has regular eye exams with a pediatric optometrist to monitor their eye health and catch any potential issues early.
