Do Blue Light Glasses Work?

by Brandon Fieger on October 10, 2020

From the time your alarm goes off in the morning and you grab your phone and start scrolling through your apps, to your end-of-the-day chill time bingeing Netflix or playing video games, in this modern, tech-driven world, your eyes are constantly exposed to blue light and you could be dealing with the side effects of blue light exposure right this moment.

What is Blue Light?

Blue light is a color found in the visible light spectrum that has a short wavelength, meaning it produces higher amounts of energy. Because of this, it comes as no surprise that sunlight is your main source of blue light, however blue light is also found in man-made sources like smartphones, tablets, computers, TVs, and other digital devices that you’re likely using all day every day. Compared to other forms of visible light, blue light scatters more easily and is not as easily focused, so when you’re looking at your laptop screen, for example, its blue light causes unfocused visual noise which your eyes have to work harder to adapt to.

The amount of blue light emitted by electronics is far less than that big glowing ball in the sky, but due to the sheer usage and proximity of digital devices to users’ faces, eye care professionals are concerned about both the short-term and long-term effects from blue light.

If you’re like the average phone user, you spend around 3 hours and 15 minutes on your smartphone alone each day. This doesn’t even account for computer, tablet, or TV time!

Symptoms of Too Much Blue Light Exposure

It’s indisputable that we spend more time looking at digital screens than ever. Working, reading, gaming, socializing, and relaxing are all tied to our gadgets. Pay attention to your body! Here are a few tell-tale signs that you’re dealing with the side effects of blue light exposure:

Digital Eye Strain

Whether you like to scroll through miles of Tik Toks or your job relies on a computer, if your eyes feel tired and dry after using your devices for long periods of time, it’s possible you’re dealing with digital eye strain (also commonly called Computer Vision Syndrome). Digital eye strain occurs because, as mentioned earlier, your eyes have to work hard to adapt to blue light. The flickering and glare on screens, as well as your reduced blinking and having to keep your eyes focused for long periods of time can cause significant strain on your peepers.

Red Eyes

If you’re spending a large majority of your day staring at screens, it’s possible you’ll take a look in the mirror and see your eyes look bloodshot! Your red eyes are trying to tell you something—you are experiencing digital eye strain and it’s time to protect your eyes from your gadgets and the blue light they emit.

After working behind a computer for hours, my eyes would become red and very tired. After one day of wearing my Foor Eyes glasses, my blue light symptoms were relieved!” -Shannon Brady


Prolonged periods of strain on the eyes, as well as blue light’s signal to the eyes’ retinas can easily cause intense headaches which can be uncomfortable, especially if your job relies on you to work on a computer. The longer you use screens unprotected, the more intense your headache can become, leaving you in discomfort throughout the day.

Disrupted Sleep

Blue light affects the body’s natural sleep cycle. Ideally, you’d wake up when the sun emits its blue light, signalling your internal clock to wake up and start your day, because blue light tells your body to stop producing melatonin, the chemical in your body that induces sleepiness. When you’re still using devices up until you try to go to sleep, your body gets confused and doesn’t produce the melatonin it needs in order to get your body ready to go to sleep, which can lead to disrupted sleep patterns.

“I didn’t know blue light was the reason why it was hard for me to get a good night’s sleep. Now, I wear my glasses while I watch TV before I go to bed and I can sleep much better!” -John Manguo

What Are Blue Light Blocking Glasses?

If you’re like most people, quitting screens cold turkey isn’t an option, and minimizing your screen time may not be enough to combat the side effects of blue light exposure. Blue light blocking glasses are a great alternative, and have become increasingly popular over the past few years as a method to combat the effects of blue light exposure caused by digital devices. 

What Do Blue Light Glasses Do?

Blue blocker glasses reduce the amount of device-emitted blue light from reaching your eyes without affecting your ability to see your screens. At Foor Eyes, our prescription-free, proprietary lenses have embedded technology that blocks harmful blue light, while leaving lenses clear and effective, with just a hint of blue tinting.

By minimizing the amount of blue light reaching the eye, blue light computer glasses can help you live a more comfortable daily life. Foor Eyes clients consistently report blue light glasses benefits, including fewer headaches, reduced eye strain and red eyes, better sleep, and more comfort living their digital lives.
