Note: With Bring Your Own Device (BYOD) and Bring Your Own Technology (BYOT) policies becoming increasingly popular in school districts across the US, Australia, Canada and the UK, we take a look at how kiddos can prevent eye problems when working on a tablet or laptop. 

John Oliver lives with his grandmother Thelma who helps him raise his twins, 8 year olds Michael and Annie, while he completes law school.

The kids still take some classes online on some days and went to school with their laptop on other days.

Like other kids they use their digital devices a lot for different reasons (Kindle device, ipad, et all).

Michael would go on and on about the most recent video he saw on Youtube!

For him, he couldn't be more pleased that he gets to take his laptop to school and use it in class, with the Bring Your Own Device (BYOD) policy recently adopted by his school.

According to Thelma, he spends between three to five hours on his laptop at school, and roughly 3 hours at home after school. We all thought it was fine because he spent the time studying afterall, so we thought nothing of it.

Until, his teacher started complaining about some worrying symptoms

She tells Thelma that Michael seems more and more distracted during classes.

"My eyes hurt!", he says. " At school, my eyes get dry, red and itchy from time to time especially when I have to use my laptop so I get anxious." 

Thelma could tell something was wrong, because Annie also experienced similar symptoms, but she didn't know what to make of it. She also noticed how his kids get really poor sleep and wake up cranky in the morning, sometimes with headaches. What could possibly be causing all of these unrelated symptoms in Michael and his sister? She felt hopeless, overwhelmed, and scared. As a retiree and with John's studies in view, the last thing she wanted was to have to spend money on expensive examinations at the doctor.

She ended up trying several different things to try to remedy their symptoms. She tried all sorts of remedies for headaches and dry eyes and poor sleep, but quickly realized this was not getting at the root of the problem.

She started to get worried! She felt hopeless, overwhelmed and scared.

If you discovered Thelma found one low-cost, simple, and instant solution to solve all of these issues instantly, would you believe it? 

Below we'll tell you what Thelma discovered and how you can use it too.

One day at the next Parent-Teacher meeting, Thelma met with Michael's teacher Miss Keane who had complained to her earlier about John's school performance. She told her that several kids had had similar complaints as Michael in her class. It turns out, one of the kids was taken to see the eye doctor who said that they were signs of Digital Eye Strain and advised them to use blue light blocking glasses for kids!

"Blue light blocking glasses for kids?" Thelma asked.

"Precisely! These are safe glasses that help protect kids exposed to blue light from digital devices" - Miss Keane

Thelma met with the parent who got them for her kids and he told Theresa what their eye doctor had told them: That digital Blue Light is the culprit of eye strain, headaches, trouble sleeping and low energy. Regardless of the device, smartphones, tablets, and computers all give off this highly concentrated blue light.(1,2)

What's worse is that anyone that spends more than 2 hours per day in front of a screen is at greatest risk of getting digital eye strain, including kids!(6) 

It didn't take long for Thelma to have the lightbulb moment. Her grandkids were being affected by Digital Eye Strain in a big way.

They were so effective that the school decided to make the glasses available for their students. Miss Keane pushed two pairs into Thelma's hands before she could say anything. "Here!" She said. "The school makes these available for each student for use at school if they need it. Let Michael and Annie try these for about a week and see if they work for them. If there's a big difference, the culprit is definitely digital eye strain."

Thelma thanked her and gave a pair each to Michael and Annie to use at school.

What happened in the next week completely blew her away.

No more headaches!

No dry, itchy eyes!

The next week proved without a shadow of a doubt that Thelma's grandkids had been suffering from digital eye strain, and these blue light blocking glasses for kids were the cure. Not ONE headache. Not ONE groggy morning. Absolutely NO dry eyes. Michael even participated more in class since he was sleeping so much better! Miss Keane even noticed that he seemed to be in a happier mood because he wasn't dealing with any of the bothersome symptoms he had been before. 

Thelma was overcome with relief at finally learning what was causing all the terrible symptoms her grandkids were experiencing, and better yet, how to solve it! She was also overjoyed that she could let them continue to enjoy the benefits of technology and their smart devices without worrying about the effects it was having on their health.

The following Friday, Thelma couldn't wait to tell Miss Keane about the transformation.

"These kids glasses worked miracles! Annie tells me for the first time in months her eyes aren't bothering her and she's not getting headaches! My grandkids are getting great sleep! THANK YOU so much!"

She asked exactly where to buy them. Miss Keane texted her the link, where Theresa immediately went and bought three pairs each for Michael and Annie (one for the house, one for school, and one pair for the car.) 

Thelma's Five Star Review:

"From the bottom of my heart thank you! My grandkids absolutely LOVE your glasses. They hardly even take them off! You've changed their lives! They seem to enjoy the time they spend using their smart devices in school even more. I've been telling all my friends about these and will continue to do so."

The Dark Side of Blue Light

Our screen time has skyrocketed since the beginning of the pandemic. Americans now average 4 hours per day just on their phone and are spending 12 hours connected to the media, according to Nielsen’s latest study.

The younger generations are spending the most time on their phone and older are watching TV. Overall, all we are spending more time than ever before sitting in front of screens or scrolling their screens. 

That's why unfortunately, Michael and Annie are not alone. As digital devices have become more and more a part of our everyday lives, so too has the prevalence of the symptoms that Thelma's grandkids had faced.

So what exactly could be causing these worrying health symptoms? What do phones, tablets, TVs, and computers all have in common? They all have highly efficient screens that output concentrated amounts of digital blue light. While the technology that surrounds us does have positives, it also has a dark side.

Excessive screen time leads to Computer Vision Syndrome.

Thelma's grandkids were experiencing what we now know as Digital Eye Strain, aka Computer Vision Syndrome (CVS). Trends in modern life and at-home entertainment mean we are exposed to this blue light on a daily basis and in large amounts. Studies show that on average, children ages 8-12 in the United States spend 4-6 hours a day watching or using screens, and teens spend up to 9 hours.(8)

The American Optometric Association states that "those persons who spend two or more continuous hours at a computer or using a digital screen device every day" are at greatest risk for developing CVS.(8) So, basically everybody kid alive today?? 

What's even worse is that many parents have no idea that digital screens are causing the symptoms they're kids are experiencing, and it may take years for them to realize the root of their problems, if they realize it all...

Blue light exposure also degrades sleep quality and health.

Michael was also suffering from the effects of blue light in a different way. Using his laptop at home in the evening was exposing him to a large amount of blue light before bed, which was greatly disrupting his natural sleep cycles by suppressing the sleep hormone called Melatonin.

The American Optometric Association states that, "[device] use before bedtime can delay sleep onset, degrade sleep quality and impair alertness the following day."(3)

Charles Czeisler, PhD, MD, and director of sleep medicine at Harvard Medical School took it a step further in a WebMD article when he was quoted saying, "The more research we do, the more evidence we have that excess artificial light at night can have a profound, deleterious effect on many aspects of human health. It is a growing public health concern."(7)

How can I protect my kids from blue light?

Short of removing screens completely, there are products that block blue light and provide safer screen time. The bad part about these products is that you'll need to buy different filters for different devices, and your wallet will empty out before you're able to get them all. That's where CoolBlue Kids come in. They offer the most advanced and affordable Blue-Blocking technology for kids.

With only one low-cost purchase, CoolBlue Kids could instantly eliminate the harmful effect that blue light could be having on your kiddos. Rather than fight against the inevitable changes in our modern society, they empower people across the world to adapt in a simple, cost-effective, and fun way!

Their glasses have amazing features like:

- UV400 coating that blocks 99% of harmful blue light

- Comfortable, easy-focus fit

- Ultra-stylish and durable kid-proof (bendy) frames

- Shatter-proof lenses

How CoolBlue Kids work:

As light from your device's screen hits the lens of their glasses, it lets the harmless red, yellow, green, and violet components of the light pass right through. Meanwhile, the harmful, high-energy blue light is reflected back, keeping it from entering the eyes of the wearer. This eliminates the nasty side effects of screen time once and for all.

The Magic of CoolBlue Kids

Below we've included a summary of our research on CoolBlue Kids to save you time. The more research we did, the more impressed we are to be honest. So much so, that we're ordering some of these for our kids (and our for ourselves! They have teens and adults glasses).

CoolBlue's Design and Function

The lenses in the CoolBlue Kids glasses are amazing. Not only does the "UV400" coating block 99% of harmful blue light, it allows harmless light to pass through, giving a virtually clear viewing experience with only a subtle tint.

They Seem Like a Great Company That Really Cares

Another thing we noticed was how many reviews talked about how great the CoolBlue Kids team was and how helpful they were in solving any issues that came up. Here's a few quotes we pulled:

"I'm impressed with this product. I also give credit to the customer service team. They are absolutely wonderful and take swift action." - Shelley D.

"great customer them to boot." - June T.

"Great glasses...Also excellent customer service from the team. Would recommend." - Annie L.

"Customer service is amazing and best company by far in dealing with customers." - Gilbert B.

Why CoolBlue Kids is #1 with kids and their parents

They're clearly a company that stands by their products, and have some amazing policies to back it up. If their products were not fantastic, these policies would surely be costing them a ton of money.

Money-Back Guarantee: They give you a full month to try the glasses out and get your money back in full if you're in any way dissatisfied with their glasses.

Lifetime Warranty: Each pair of glasses comes with a warranty for LIFE that covers broken AND lost pairs. 

Guaranteed Fit Policy: They do a pretty good job of sizing their glasses, but sometime customers need to size up or down. All you have to do is send them a quick email and they'll send you another pair in the right size COMPLETELY FREE! How cool is that??

Sounds amazing... But how much do they cost?

If you've ever had to buy glasses at the eye doctor you probably know they can cost hundreds of dollars, and that's WITH insurance.

The CoolBlue Optics company, a family-owned business based in Portland, OR, understands the need for their eyewear to be as affordable as possible for as many families as possible so everyone can benefit.

Normally, a pair costs $36.99 USD, but right now they're running a Holiday Bundle 50% OFF Sale (that's ending soon), so you can get 3 pairs for only $18.33 each! Just make sure you choose a bundle option when you check out.

How can they cost so little?

Because they are a family-owned, direct-to-consumer brand, they don't have to charge the high price markups that a bigger retailer does.

They cut out the middleman and keep their prices low with proprietary manufacturing and low overhead costs, so they can provide amazing value to their customers. They care deeply about the impact they have on people's lives (unlike big box retailers, who charge crazy prices to cover costs and make profit).

Low cost does not mean low quality though. CoolBlue Kids are premium eyewear, and they take pride in creating the best glasses for the best value.

How do I know if my kids need CoolBlue Kids glasses?

We're going to take a wild guess and say that your kids are probably like 99% of the kids in the world, and they spend 2, probably more, hours in front of screens every single day. That's a whole lotta blue light! And that makes them a great candidate for blue light glasses, even if they don't have symptoms yet. 

You teach them to brush their teeth everyday to preserve their dental health. Why would you not give the same care and attention to their eyes? Imagine them feeling like they can they can succeed in school with the use the technology they love. If your kids are suffering from symptoms of digital eye strain and you wish they could experience the same relief Michael, Annie and their grandmother felt, check these out.

Don't Take Our Word For It.
