"I Tried Blue Blockers For My Dry Eyes and Headaches - Here's What Happened"

Note: This story will change the way you look at screens forever. We're going to tell you about the unknown dark side of modern technology, how it could be affecting you and your family, and what you can do about it. 

Published 8 Hours Ago | By Elisa Carlson

New York (Eye Care Trending) - Theresa Randall, like many of her friends, spent the majority of her day reading on her tablet, walking, spending time with her two grandsons and watching her favorite shows on TV. A 68 year old retiree, her and her husband John enjoyed themselves the most watching movies together and spending time with family and friends. Between reading on her tablet and watching TV, Theresa spent between five and six hours per day on digital devices. She thought this was fine, because all her friends and family spend at least that much time in front of a screen per day, so she thought nothing of it. 

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

"They started when my daughter got me a smart tablet for my birthday, I didn't use it much at first but once I downloaded my books onto it I found myself using it more and more, that's when the symptoms really started. Dry, Itchy eyes and Terrible headaches multiple times a week, and I was getting really poor sleep. Waking up in the morning groggy and sleepy... When it first started I was concerned, but when things kept progressing it became clear that something was wrong, and I started to get worried..."

Theresa could tell something was wrong, but she didn't know where to start. What could possibly be causing all of these unrelated symptoms in both her and her husband at the same time? She felt hopeless and overwhelmed, and scared. As a retiree, the last thing she wanted was to have to spend money on expensive examinations at the doctor.

Theresa ended up trying several different things to try to remedy her 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.

If you discovered Theresa 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 Theresa discovered and how you can use it too.

One day when she was having breakfast with a few friends, she noticed her friend Maura put on a pair of clip-on lenses as she was pulling her phone out of her purse. Curious, she commented on how Maura looked great in them and asked why she hadn't been wearing them the whole time they were at breakfast.

"Oh, thank you!" She said. "But these, believe it or not, these are the best things I've ever bought for my glasses! They're called blue light blocking clip-ons. I was suffering from Digital Eye Strain, and my doctor told me to get these.”

“We started to get into a conversation and I learned that Maura had been experiencing the same symptoms as me. Terrible headaches throughout the week, dry eyes, and trouble sleeping” Theresa said.

She told Theresa what her eye doctor had told her: 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.(6)

 It didn't take long for Theresa to have the lightbulb moment. She was being affected by Digital Eye Strain in a big way.

Maura pulled out a second pair from her purse and pushed them into Theresa's hands before she could say anything. "Here!" She said. "I always keep an extra pairs with me in my purse. Try these out for about a week and see if they work for you. If there's a big difference, the culprit is definitely digital eye strain."

Theresa thanked her and put the clip-on lenses in her purse to try at home later when she was reading on her tablet.

What happened in the next week completely blew her away.

"I wore them that day during the time when I was reading on my tablet and watching TV in the evening. I did notice that my eyes didn't get dry and I didn't get a headache, I also thought the next morning that I had been able to get to sleep faster than normal that night. That's interesting I thought, but it could just be a good day."

But it didn't stop there...

The next week proved without a shadow of a doubt that Theresa had been suffering from digital eye strain, and these clip-ons were the cure. Not ONE headache. Not ONE groggy morning. Absolutely NO dry eyes. She even had more energy during the day because she was sleeping so much better! Her friends even noticed that she seemed to be in a happier mood because she wasn't dealing with any of the bothersome symptoms she had been before.

Theresa was overcome with relief at finally learning what was causing all the terrible symptoms she was experiencing, and better yet, how to solve it! She was also overjoyed that she could continue to enjoy her books on her tablet and watch her favorite TV shows without worrying about the effects it was having on her health.

The following Friday, Theresa couldn't wait to tell Maura about her transformation.

"These clip-on lenses worked miracles! For the first time in months my eyes aren't bothering me and I'm not getting headaches! Also I'm getting great sleep! THANK YOU so much!"

She gave her pair back and asked exactly where to buy them. Maura texted her the link, where Theresa immediately went and bought three pairs (one for the house, one for her purse, and one pair for her husband, since he had been getting dry and tired eyes from screen time as well.)

Theresa's Five Star Review:

"From the bottom of my heart thank you! My husband and I both LOVE your glasses. I hardly even take them off! You've changed our lives! My screen time throughout the day has gotten more enjoyable too. I've been telling all my friends about these and will continue to do so."

The Dark Side of Blue Light

"Over 60% Of Adults Are Estimated To Suffer From Computer Vision Syndrome"

Anyone who spends 2+ hours on screens per day is at risk. Symptoms include:

  • Dry Eyes
  • Tired Eyes
  • Blurry Vision
  • Eye Soreness
  • Headaches
  • Trouble Getting To Sleep

Unfortunately, Theresa is 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 Theresa and her husband 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.

Theresa and her husband 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 the average adult now gets more than 8 hours of screen time per day.(6)

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 alive today??

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

Blue light exposure also degrades sleep quality and health.

Theresa was also suffering from the effects of blue light in a different way. Watching TV in the evening was exposing her to a large amount of blue light before bed, which was greatly disrupting her 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 eyes 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 Clip-Ons come in. They offer the most advanced and affordable Blue-Blocking technology in one easy clip-on lens.

With only one low-cost purchase, CoolBlue Clip-Ons could instantly eliminate the harmful effect that blue light could be having on you. 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.

CoolBlue Clip-Ons Attach To Any Pair of Glasses in Seconds

Their glasses have amazing features like:

  • Easy To Use - Clips on to your glasses in seconds with only a light squeeze of the clip.
  • Works With Any Glasses - They can easily clip on to any glasses you own (readers or prescriptions).
  • Made To Last - Lenses are made of shatter-resistant polycarbonate
  • Portable - Each pair comes with a protective pouch so you can take them anywhere with you.
  • UV 400 Lens Tech - Blocks 99% of harmful blue light while preserving a natural viewing experience with virtually clear lenses.
  • Cost-Effective - CoolBlue Clip-Ons cost a fraction of getting a new pair of prescriptions with blue blocking.

How CoolBlue Clip-Ons 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.

CoolBlue Clip-Ons block harmful blue light with their advanced filter technology

CoolBlue's Design and Function:

Weighing in at only 11 grams, CoolBlue Clip-Ons are engineered to provide the perfect balance of comfort and durability. They are the lightest clip-ons on the market that utilize shatter-resistant UV 400 lens technology.

The Company Cares About Their Customers:

Another thing we noticed was how many reviews talked about how great the CoolBlue Clip-Ons 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." - Nayoma I.

"great customer them to boot." - Carly B.

"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." - Mechel B.

Why CoolBlue Optics is #1 With Older Adults:

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 $39.99 USD, but right now they're running a Spring Sale (that's ending soon), so you can get 3 pairs for only $19.99 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 Clip-Ons are premium eyewear, and they take pride in creating the best glasses for the best value.

How do I know if CoolBlue Clip-Ons are right for me?

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

You brush your teeth everyday to preserve your dental health. Why would would you not give the same care and attention to your eyes? Imagine feeling like you can tackle the workday or enjoy television without dealing with dry, tired eyes. If you are suffering from symptoms of digital eye strain wish you could experience the same relief Theresa felt, check these out.

Don't Take Our Word For It.
