Why You NEED Blue Blocking Glasses

Why You NEED Blue Blocking Glasses

You probably already know how blue light can disrupt your sleep.

Other than sleep, do you know how else blue light can affect your health?

You also know that blue light comes from computers and cell phones.

But do you know the other ways you can get exposed to blue light?

In this post, you'll discover the different ways blue light can affect your health, the different ways you get exposed to it, and how you can protect yourself from overexposure to blue light.

Firstly, what is blue light? 

Blue light is simply a color of light on the visible light spectrum.


As you can see, we can’t see ultra violet (UV) light or infrared light, but we can see everything in between.

If you go from left to right, UV light has the shortest wavelengths and the highest concentrations of energy. Infrared light has the longest wavelengths and the lowest concentrations of energy.

Is blue light dangerous?

Like most things in this world, it’s the amount you get (and time you get it) that determines if it can negatively impact your health.

Since humans first appeared on earth, we’ve been getting natural blue light from the sun. The natural blue light we get from the sun helps us stay awake and provides small increases in alertness during the daytime. On days when the sky is clear and the sun is shining, the sky is blue because all of the blue light that is being emitted by the sun is scattered throughout the atmosphere. As the sun sets, more yellow and red light gets scattered, making for those beautiful sunsets we all love.   

The negative impact of blue light comes from our overuse of artificial blue lights during the day and night, mostly through computer and phone screens.

How can blue light affect your health? 

Blue light affects your health in many ways. Here’s a short list:


1. Blue light makes it harder to fall asleep and decreases the quality of your sleep.

Blue light can negatively impact your sleep due to the fact that it suppresses your sleep hormone melatonin. Melatonin has a lot of functions in the body. The main things melatonin does is to tell your body to relax and to lower your body temperature at night. Both of these things help create a deep, restful sleep. If you suppress melatonin production at night with too much blue light, this will disrupt your circadian rhythm and lower the quality of your sleep.


2. Eye Strain and potential long term complications.

Blue light contains high amounts of energy. When direct sources of blue light (such as computer and phone screens) enter your eyes for long periods of time - such as during work - this can make your eyes work extra hard to cope with the blue light and lead to eye strain. Over sustained periods, the exposure can contribute to long-term vision issues such as cataracts and age-related macular degeneration (AMD).

3. Blurry Vision.

Your eyes don’t filter out blue light. That means that when you’re on your computer or phone for extended periods of time, you’re getting in large doses of blue light and less amounts of the other colors on the spectrum. Since different colors have different wavelengths and refraction properties, this can lead to an imbalance in your focus on different colors and create blurry vision.

4. Headaches

Very common causes for headaches are light sensitivity and too much stress on the eyes. Exposure to blue light, especially bright, concentrated sources of blue light, can trigger headaches.

5. Dry Eyes.

When you stare at your screen for long periods of time, your eyes can get locked into a certain focal point and you’re less likely to blink. Blinking produces moisture for your eyes. So when you don’t blink for long periods of time, your eyes become dry. Always take breaks every few minutes to look away from your screen and blink.

6. Hard to focus

The eye strain and headaches created from blue light clearly makes it harder to focus. It’s a terrible feeling not being able to concentrate because your head and eyes just aren’t cooperating. 

7. Digital Eye Strain

Digital eye strain is an umbrella term used to describe the different negative effects people experience from too much blue light. The different problems associated with digital eye include everything we just talked about:

  • Sore, dry, itchy, or red eyes
  • Headaches
  • Sensitivity to light
  • Sore neck and shoulders
  • Blurred vision
  • Poor sleep

Where do you get exposed to blue light?

The main source of blue light is the sun. For most of us, this doesn’t pose a problem. The problems arise when we get too much blue light from other sources like:

  • Computers
  • Phones
  • Tablets
  • Televisions
  • Lightbulbs
  • Alarm clocks 
  • Air purifiers in the bedroom
  • LED lights
  • Fluorescent lights
  • Refrigerator and freezer lights (late night snack anyone?)
  • Printers
  • Motor vehicle dashboards
  • Outdoor advertising
  • Blue neon lights
  • Those laser lights and giant screens at festivals 
  • Literally any light source that emits blue light

That’s right… blue light doesn’t just come from your computers and phones. 

It’s everywhere.

How do you protect yourself from blue light?

There are a lot of ways you can protect yourself from blue light.

You can:

  1. Turn off all of the lights in your house once the sun goes down (lol)
  2. Not use your phone or computer at night (even bigger lol)
  3. Turn down the brightness on your phone and computer at night and use night mode and other software.
  4. Wear blue blocking glasses to protect you while you’re on your computer, on your phone, in the bathroom, getting a snack from the fridge, and anything else. Since glasses are placed right in front of your eyes, they provide the best protection from blue light because no matter where the light is coming from, it will be filtered by the lenses on the glasses.

Blue blocking glasses are the most effective form of blocking blue light because it provides all-day protection from every source of blue light. 

By wearing blue blocking glasses at work and at home, you can help protect yourself from digital eye strain, sore eyes, dry eyes, headaches, blurry vision and poor sleep.

If you experience any of these things, try a pair of blue blocking glasses today.

The Classic Pro's are our most popular pair.
