For a lot of people, a day in their life includes being in front of a computer screen or using their phones most of the time, and kids nowadays are no exception to that. Eyeglasses that are equipped with blue light filters are designed to help block the harmful blue-violet lights that emit from our phones and computer screens.
What Are Blue Light Glasses?
Blue light is actually everywhere around us as it’s found in the sun’s rays and from the screens of electronic devices.  So, while everyone is exposed to blue light from the sun, nowadays, more than ever, people, from kids to adults, are glued to their more damaging gadgets. The extreme exposure to blue light from electronic devices has been a cause of concern since it can affect anyone.
Professionals have come up with a solution to lessen the impact of blue light. Excessive exposure can destroy retina cells, and in extreme cases, it can even trigger the onset of blindness.  The blue light glasses are made specifically to help filter out the blue light coming from electronic devices.
The eyeglasses contain surface coatings on the lenses that block the blue light emitting from the screens. They can be used to avoid eye strain and reduce headaches when spending too much time in front of screens. Blue light glasses for kids are also available and have become an increasing need during the past year because of the introduction of online classes throughout the world.
Blue Light Glasses Benefits
Wearing blue light glasses is said to provide numerous benefits for kids who spend a lot of time online. Let’s be honest, the amount of time spent in front of digital screens is not about to decrease anytime soon. Assistance is very much needed to slow down the impact of blue light rays. The glasses can help avoid Digital Eye Strain or Computer Vision Syndrome.
Here are some benefits to wearing blue light glasses:
Being exposed to an excess of blue light from the screens can trigger headaches and migraines. Wearing the glasses can help prevent or reduce migraine attacks as the blue light gets filtered.
Some research has suggested that wearing glasses can have an impact on sleep quality. Technology has certainly impacted sleeping patterns, especially for kids who are often immersed in technology. 
Researchers have stated that blue light from the screens delays the release of melatonin which is a sleep-inducing hormone that is released by the body a couple of hours before sleeping. The glasses can help increase the production of melatonin since the blue light is filtered. This enables a better night’s sleep without compromising productivity at night.
Decreased Eye Strain
Too much screen time, whether it’s from phones, televisions, or computers, can have kids experiencing Computer Vision Syndrome. Some symptoms might be dry eyes, fatigue, headaches, and poor posture.
Blue light glasses can help kids, especially those participating in online classes, decrease eye strain and be more alert as they can help eliminate those symptoms. The glasses can also help in improving concentration since they block the blue light making it easier to focus.
Reduce Risks of Eye Diseases
The retinas in the eyes are protected by the lenses and cornea from harmful UV lights, but blue light is not one of them. If the retina is damaged, it can lead to diseases like macular degeneration, which can ultimately lead to blindness. Cataracts can also be caused by extreme exposure to blue light. The glasses can help protect the retinas from blue light and prevent long-lasting eye conditions.
Do Blue Light Glasses Work?
The glasses are marketed to be extremely beneficial to those who wear them, especially if a lot of time is spent in front of screens. Here’s the catch though, there has not been a lot of research to make a definite conclusion about the effectiveness of blue light glasses for kids.
The glasses can reduce the amount of blue light that enters the eyes, but there is no research to support the claims that the glasses have scientifically-proven benefits. 
According to a study published in January 2019, the special filters found on the glasses do block the blue light, but they didn’t prevent digital eye strain symptoms from showing up.
It is important to remember that Computer Vision Syndrome does not only come from blue light, but also from how the gadgets are used. The amount of time spent in front of a screen has a bigger impact on eye health. Checking with an optometrist is a great option to find out if your kids require blue light glasses.

As mentioned before, blue light glasses have filters that can help, but it would still depend on how much time is spent in front of digital monitors that would play a part in triggering symptoms.

One common denominator from the different studies is that the blue light glasses filter out the emissions coming from screens. The benefits do not have scientific results to stand on and they often come from the manufacturers of those glasses.
Some glasses are quite expensive and are not suggested by some to invest in considering the lack of research about the subject. It is better to try out some of the cheaper ones which offer the same features.
According to professionals, the best way to lessen the symptoms is to control or modulate the time spent by your kids on their devices, especially if it does not involve online classes anymore.
Using digital screens for long periods can be harmful, as the screens emit blue light. Research is scarce regarding the subject at this point. Hence, there is no detailed explanation as to how blue light glasses for kids can significantly improve their eye conditions. You can always consult an optometrist if symptoms start to show up.
