Better Household Living


Monday, January 10, 2021  |  By Elisa Carlson


Lisa Darling, like most other single moms of two, spent the majority of her day either at the clinic where she worked, driving to and from the clinic, or driving her kids to and from school. Her two sons, Noah and Lucas, were in grades 2 and 4. Between school and gaming, they were spending 6+ hours per day on computers, phones, and tablets. Lisa thought this was ok —  she HAD to be ok with this because she already felt worked to the bone and the kids either needed devices for school or for entertainment.

That is, until she started to notice some really worrying symptoms.

"They started when Lucas had just turned 9. Terrible headaches multiple times a week, and I could tell his sleep was starting to get really bad. He would wake up in the morning cranky and sleepy, and his teacher even called me to ask if everything was ok at home because he had been not doing well in school either..."

On top of that, she also noticed Noah rubbing his eye excessively and complaining that his eyes were "tired" even in the middle of the day when he should have been at peak energy.

Lisa could tell something was very wrong with the way her kids were acting, but she didn't know where to start. What could possibly be causing all of these unrelated symptoms in both of my kids at the same time? She felt hopeless and overwhelmed, and scared. As a single working mom, she didn't have the time, let alone money, to pay for expensive examinations at the doctor.

But one day as she was dropping them off at Friday day care, she noticed Lucas' friend Mason with glasses for the first time she could remember. Curious, she went to go talk with Mason's mom to tell her he looked adorable and to ask how he was liking prescription glasses.

"Oh, thank you!" She said. "But these, believe it or not, aren't prescription glasses! They're called blue light blocking glasses. Mason was suffering from Digital Eye Strain, and his doctor told us to get him these.”

“We started to get into a conversation and I learned that Mason had been experiencing the same worrying symptoms as Lucas. Terrible headaches throughout the week. Trouble sleeping and morning crankiness,” Lisa said.

Digital Blue Light is the culprit of eye strain, regardless of the device. Smartphones, tablets, and computers all give off this highly concentrated blue light.(1,2)

What's worse is that a child's retina absorbs more blue light than adults,(3) and anyone that spends more than 2 hours per day in front of a screen is at greatest risk of getting digital eye strain.(6)

It didn't take long for Lisa to have the lightbulb moment. Lucas and Noah were being affected by digital eye strain in a big way.

Mason's mom pulled out a pair from her purse and pushed them into Lisa's hands before she could say anything. "Here!" She said. "I always keep an extra pair with me in my purse. Have Lucas try these on and see how he likes them. They're called CoolBlue Kids. If there's a big difference, the culprit is definitely eye strain. They also make glasses for adults that you should check out."

Lisa thanked her and ran to give Lucas his glasses before heading off to work for the day.

What happened in the next week completely blew her away.

"I went to pick up my sons after work that day, tired but anxious to see my kids. Lucas and Noah seemed to be in a good mood, and the daycare worker said Lucas was feeling good all day with no headaches. That's interesting I thought. He could just be having a good day. He has those sometimes."

But it didn't stop there. She asked Lucas to hand the glasses over to her as they got back in the car, but Lucas didn't want to. He absolutely loved wearing them and didn't want to take them off.

He kept them on for much of the evening, especially when they were watching a movie before bed. The next day, she couldn't believe her eyes.

“Lucas looked bright-eyed and fresh-faced like I had never seen him before! His mood was very positive and said he slept good. OK, I thought, This is starting to seem like a pretty odd coincidence after getting those glasses…”

The next week proved without a shadow of a doubt that Lucas had been suffering from eye strain, and these glasses were the cure. Not ONE headache. Not ONE complaint in the morning. Not ONE comment from the teacher. She was still having trouble believing it.

The following Friday, Lisa rushed up to Mason's mom to tell her.

"These glasses worked miracles on Lucas! For the first time in months he's not complaining of headaches and he's getting great sleep! THANK YOU so much!"

She gave her pair back and asked exactly where to buy them. A couple minutes later, she shared a link with her over text to the CoolBlue Optics website, where Lisa immediately went and bought three pairs (one for Lucas, one for Noah, and one pair for herself, since she was on the computer all day too.)

Lisa's Five Star Review:

"From the bottom of my heart thank you coolblue optics! My sons and I both LOVE your glasses. He loves the novelty of wearing them and won't even take them off! You've changed our lives! I also admit, I got a pair of the coolblue parents and I've found my hours of work at my desk job have gotten more enjoyable too. I've been telling all my friends about these and will continue to do so."

Why is blue light dangerous?

Blue light exposure from digital screens can result in various symptoms including:

Eye Strain

Blurry Vision


Poor Sleep

Electronic devices of today utilize highly concentrated blue light to illuminate their screens. Trends in the modern classroom and at-home entertainment mean our children are exposed to this blue light on a daily basis and in large amounts. Kids ages 8 and up get an average of 4-6 hours of screen time per day.(4)

In a Web MD publication, director of sleep medicine at Harvard Medical School, Charles Czeisler, PhD, MD 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."(5)

How can I protect my kid's (and my own) eyes from blue light?

Short of taking screens away 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 Optics comes in. They offer the most advanced and affordable Blue-Blocking technology for little ones and adults alike.

With only one low-cost purchase, CoolBlue Kids could instantly reduce the harmful effect that blue light could be having on your child. Rather than fight against the inevitable changes in our modern society, they empower families 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-durable and bendy frames

Shatter-proof lenses

How CoolBlue Optics glasses 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.

Do they have Clip-On Lenses?

CoolBlue Optics has designed a clip-on solution for adults! They can easily clip on to any pair of glasses and provide the same great blue blocking experience. Check them out here.

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 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 between $35 and $40 dollars, but right now they're doing a 50% OFF New Years Bundle Sale (that's ending soon).

How can they cost so little?

Because CoolBlue Optics is 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 these families' lives (unlike big box retailers, who charge crazy prices to cover costs and make profit).

Low cost does not mean low quality though. CoolBlue Optics are a premium eyewear brand that takes pride in creating the best glasses for the best value.

We love coolblue kids! I bought these for my 7yo daughter who is complaining about headaches recently and I was wondering if it was related to screen time. I noticed she was rubbing her eyes after being on the iPad for longer than 20 min. After 2 weeks with the glasses there have been no headaches and I could not be happier. will definitely be telling my friends about these.

These glasses are a hit with my daughter she won’t even take them off! She started distance learning and right away getting headaches frequently after spending hours in front of a screen. There have not been any headaches since she has started wearing them!

My son is doing online school this fall i found these to be a must have after considering what blue light could be doing to his eyes. He loves the glasses and has no problem putting them on when (quite enthusiastically I must say) its his time to play on the computer.  A+
