HOW BLUE LIGHT AFFECTS
YOUR CHILD’S HEALTH

Brand Ambassador Zack Martinez

The rise of screen time usage and the never-ending use of smartphones has left parents wondering if their kids should have smartphones and if so, at what age. Even if your child is the exception, it is still important to know all of the effects of the blue light on your child.

Blue Light and Your Child’s Eyes

Blue light has shorter wavelengths and higher energy than other colors. Research shows that blue light is a factor in macular degeneration. Macular degeneration is an eye disease that can lead to blindness. Blue light contains rays with wavelengths between 415 and 455 nanometers, which is close to that range. Most of the light used in televisions, computers, smartphones have wavelengths between 400 and 490 nanometers, which are similarly short wavelengths as those in blue light harmful to our eyes.

Based on findings from the National Eye Institute, it would appear that younger people are impacted more by digital screens than adult viewers. The study found that children’s eyes absorb more blue light from digital device screens than adults that can lead to eye strain. Anti-blue light glasses can help reduce the risk of digital eye strain on your kids.

Blue Light and Sleep Cycle

Artificial blue light from electronic devices can mess with your circadian rhythm (or sleep cycle), which signals your brain to wake up when it should be winding down. In one study, as little as 2 hours of exposure to blue light at night slowed or stopped the release of the sleep hormone melatonin. Unplugging your child’s digital devices at least 3 hours before bedtime will help them get better rest.

Blue Light and Sun

Young children are like plants. They need sunlight to grow and be healthy. Just like your garden, if a young one is missing out on regular sunlight exposure in the early stages of their life, that could have an effect on their long-term vision and growth. In fact, scientists say the increase in myopia and nearsightedness today may be linked to kids spending too much time indoors on computers, and not enough playing outdoors where they can get blue light exposure from the sun.

What Should You Do?

While the effects of Blue light have still not been completely researched, we do know that the eyes are very susceptible to health issues from using devices excessively. The best proactive steps you can take as a parent is to encourage your children to stay healthy by giving their eyes some much-needed rest. You can do this by suggesting they follow the 20-20-20 break rule every day. This breaks down like this: taking a 20-second break every 20 minutes and focusing on something that is 20 feet away for each break. As well, you might want to consider changing settings on various electronic devices or wear anti-blue light glasses so that blue light is reduced when possible.

DO ANTI BLUE LIGHT GLASSES WORK?

Many parents are concerned about the harmful effects of blue light on their children. Blue light from the sun and man-made sources such as phone screens and computer screens seem to be a huge problem for kids. It can cause eye strain, sleep problems, and headaches, and can suppress melatonin. There is a lot of buzz about anti blue light glasses for kids, but do they really work?

Eye strain is one of the most common complaints today as kids are spending more and more time staring at digital screens. These glasses that filter blue light are gaining popularity because they claim that they can help lessen eyestrain, improve sleep habits, and prevent eye disease.

Wearing blue light glasses improved sleep quality and quantity, according to a study published in the journal Applied Psychology in 2021. Work performance was also improved when the glasses were worn.

There is still an ongoing study on how effective these blue light glasses but doctors said that these blue light glasses are likely no harm, especially on kids.

Aside from wearing anti blue light glasses, you can also use these tips to help reduce your kid’s exposure to blue light.

Limit the amount of screen time

You can help your children’s circadian rhythm by limiting their use of electronic devices after classes are over.

Practice the 20-20-20 Rule

Many doctors have recommended this method to reduce digital eye strain. Once your kid is using digital screens for an hour or more, let them look every 20 minutes at an object 20 feet away for 20 seconds.

Decrease Screen Brightness

Minimizing screen brightness helps reduce eye fatigue and strain, and also decreases the damage done to the eyes. Darker colors on the screen make it easier for the eyes to adjust to the changing brightness.

Proper Posture

A study done has found that if a person’s computer screen is at eye-level, his cognitive performance increases by 30%. This is because the neck does not have to flex down to look at your work. The study also found that if you support your child’s feet, his cognitive performance is improved by 10%.

Take Breaks

If your kids are between the ages of 3 to 4, you need to make sure that they are getting enough exercise. Aim to ensure that they are getting at least an hour of moderate- to vigorous-intensity exercise every day.
