4 Telltale Signs You Have Computer Vision Syndrome

Monday, December 9, 2021  |  By Carla Wilcox 

Recent studies show that over 60% of adults suffer from Computer Vision Syndrome. Read on to find out what this condition is, why it happens, and how to stop it. 

On a drizzly, mid-autumn afternoon two weeks ago, Jeffrey Anderson sat in the examination room at his local eye doctor’s office. Minutes ago the doctor took images of his corneas and performed multiple tests designed to identify any changes in his vision and evaluate his overall eye health. In the previous weeks, Jeffrey had noticed some worrying symptoms: blurry vision, redness in the eyes, headaches, dryness, and tiredness. Because his symptoms all seemed to be related to his eyes, his first stop was the eye doctor. As he sat waiting anxiously for the doctor's findings, he found himself wondering what could possibly be causing these symptoms, and how he could fix them. As he pondered, the doctor opened the door and walked over to Jeffrey. 

“Jeffrey, I have some good news and some not-so-good news.”

“What’s the not-so-good news?”

“Well, it seems you are suffering from a condition called ‘Computer Vision Syndrome.’ It’s a condition caused by looking at digital screens that causes eye strain, which leads to the symptoms you’re experiencing.”

“Ok, so what’s the good news?”

“Well, Jeffrey. There’s an easy way to fix it…”

Screens are everywhere nowadays, they’re unavoidable. Whether talking to our kids or grandkids, reading email, or watching the news, a huge part of our lives takes place on our digital devices. It’s easy to see the benefits that technology provides for many of us, but the reality is that technology can also take a toll. 

What Is Computer Vision Syndrome?

The average adult in 2021 spends 8.5 hours in front of a screen every single day. What’s more, the average household has more TVs than people and has them on for an average of 8 hours per day.(1) To say screen time really adds up is the understatement of the century. 

The term Computer Vision Syndrome is used when this screen time becomes overwhelming to our eyes and creates a chronic condition of strain, manifesting in symptoms such as dry, tired, itchy or red eyes, headaches, and trouble sleeping. Some studies have even found that Computer Vision Syndrome leads to an increase in macular degeneration, an irreversible condition. Recent estimates have found that over 60% of adults suffer from Computer Vision Syndrome.(2)

Why are our eyes strained by computers? The answer lies in the light produced by our devices’ screens. This light is composed of many different wavelengths that together create the complex colors we see on our screens. The main offender in this concoction of wavelengths is blue light, the highest-energy wavelengths in the visible spectrum. While natural light, including sunlight, contains blue light, our digital devices give off this light in highly concentrated amounts. Only slightly lower energy than UV light, the blue light emitted by your screen has enough energy to reach the retina of your eyes and cause the strain and potential degeneration associated with Computer Vision Syndrome.

How Do I Know If I Have Computer Vision Syndrome?

Anyone who spends two or more hours in front of a screen per day is at risk for Computer Vision Syndrome. Below we’ll go over some of the telltale signs you’re being affected, and what you can do about it. 

1. Your eyes feel dry, tired, or itchy.

Have you ever watched a movie or TV in the evening, only to find yourself rubbing your eyes, blinking hard and often, and having that dry, tired eye feeling? This is one of the most common and frustrating symptoms of Computer Vision Syndrome, and it can happen any time you’re in front of a screen for an extended period of time. 

2. Headaches

Hours spent straining your eyes at the computer or in front of the TV can cause headaches. We’ve all been there, a long day spent in front of screens ends up with your head aching. If you experience this, you may be experiencing Computer Vision Syndrome. 

3. Blurry Vision

The strain screen time puts on your eyes can result in blurry vision and difficulty focusing your eyes. If you experience this symptom, it may be from extended time in front of a screen.

4. Trouble Sleeping

The blue light emitted from digital screens actually has a secondary effect besides straining your eyes. Blue light entering your eyes can also suppress the sleep hormone melatonin. Ever been up late watching TV and felt like you should be ready for sleep but you’re not even tired? You can thank blue light for that.

If you’ve experienced one or more of these symptoms, you may have Computer Vision Syndrome. But here’s the good news…

There is a Solution (And Yes, You Can Still Watch TV)

Remember Jeffrey from the beginning of this article? You’re probably wondering: what was the easy solution to Computer Vision Syndrome his eye doctor was referring to?

The answer: Blue Light Blocking Lenses

There are products available online that you can clip-on to the glasses you already wear that will instantly turn them into blue light blocking glasses that can prevent Computer Vision Syndrome. In order to save you time, our researchers scoured the web to find the best pair of clip-on blue light glasses available. Here’s what we found:

Our #1 Pick for Blue Light Blocking Lenses

After extensive research, we have concluded that the best blue light blocking lenses for most people are from a brand called CoolBlue Optics. Their flagship product: CoolBlue Clip-Onsare a revolutionary new product that clips on to any pair of glasses and blocks harmful blue light from ever entering your eyes, thereby preventing Computer Vision Syndrome while still allowing you to enjoy screen time.

What Are They?

CoolBlue Clip-Ons block 99% of harmful blue light that is responsible for Computer Vision Syndrome.

The CoolBlue Optics company was founded by 2 Oregon brothers who were tired of suffering from headaches and discovered that blue light was the problem. They set out to find a way to get blue light blocking technology into the hands of more people at an affordable price.
