Blue-light blocking glasses that help to protect your eyes when you use the computer for extended periods of time have become really popular in recent years. Here are the best blue light blocking glasses that you can buy without putting a hole in your pocket.

What is Blue Light?

blue light

Sunlight is made up of the colors of a rainbow -  red, orange, yellow, green, blue, indigo and violet light. When these seven colored lights are combined, it becomes the white light that we see. Rays of different colors have different energy and wavelength.

Red rays have less energy and longer wavelengths while on the other end of the spectrum, blue rays have more energy and shorter wavelengths. Even though light looks white, it can have a large blue component, meaning that the eyes are exposed to a higher amount of blue rays which have a longer wavelength.

The following chart shows the entire electromagnetic spectrum and how the wavelengths within the visible spectrum varies as it progresses from blue to red.

Where are you exposed to blue light?

The sun is our biggest source of blue-light

Digital devices like computer screens, televisions, smartphones, laptops and tablets emit bluish (shorter wavelength) light. According to a survey done by Acuvue, office workers spend around 6.5 hours a day in front of their computers at work.

It's not just screen time at work, though. In a survey done by Pew research, half of young adults between the ages of 18 and 29 responded that they were online constantly.

While we spend long hours in front of the computer and other digital devices, our biggest source of blue light is actually the sun. Here are some of the more common sources of blue light, including:
  • Fluorescent light
  • LED light
  • LED televisions
  • Computer monitors
  • Tablet screens
  • Smart phone screens
Our blue light exposure from digital device screens is actually rather small compared to how much we receive from the sun and yet there is so much fuss about it. Why?

For one, we spend a good deal of time looking at screens and they're usually pretty close to our eyes. Also, studies have shown that digital device screens impact the eyes of children more than adults.

What are the harmful effects of blue light?

Almost all visible blue light reaches the retina and this light may not only affect our vision but could also cause our eyes to age prematurely. Some of the harmful effects of blue light on our eyes include:

Eyestrain: Sitting in front of the computer can lead to eyestrain because the blue light from the screens reduce the contrast. This leads to sore eyes or having trouble focusing.

Retina damage: Continued exposure to blue light over time could damage retinal cells. This is a cause of vision problems like age-related macular degeneration.

Disrupted circadian rhythm: short wavelength blue light can delay the release of the sleep inducing hormone, melatonin, pushing our internal clock to a later schedule.  

Blue light isn't all bad. There are benefits of blue light?

While the negative impact of blue light gets all the headlines, some blue light is needed for optimum health. Here are some of blue light's positive effects:
Not enough exposure to sunlight in children could affect the growth and development of the eyes and vision. Early studies show a deficiency in blue light exposure could contribute to the recent increase in myopia/nearsightedness.

How should we protect our eyes from blue light?

There are a couple of ways to protect your eyes if you feel that exposure to digital devices is causing eyestrain or affecting your sleep:

Reduce screen time: The first thing you should try to do is to reduce the amount of time spent in front of your screen and to take frequent breaks in between so as to give your eyes a rest.

Filters: You can place a filter over your smart phone, tablet or computer screen. These filters help to reduce the amount of blue light that reaches your retinas.

Blue-light Filtering glasses: As the name suggests, these glasses block the blue light from screens reaching your eyes and can help with eye strain.

Anti-reflective lenses: These lenses increase the contrast and reduce the glare of the screen. They are pretty helpful as they can also help to block blue light from the sun.

What are the benefits of wearing blue light blocking glasses?

Protective lenses such as blue-light filtering glasses help to reduce the amount of blue-light that reaches the retina of our eyes. Here are some of the benefits of wearing them:

Reduce eye strain: By improving the contrast from the screens and reducing the amount of blue-light reaching our retinas, blue-light blocking glasses can help to reduce the strain on our tired eyes.

Improve sleep habits: Having trouble falling asleep at night after working on the computer? Blue-light blocking glasses help to ensure that melatonin production is not delayed before sleep time ensuring that we feel sleepy at the right time in order to get enough hours of sleep.

Mitigate age-related macular degeneration: Just as with eye-strain, reducing the exposure to blue light rays helps to delay the macular degeneration that happens as we age.

Do blue light blocking glasses work?

There's a lot of hype about blue-light blocking glasses but do they even work? The FDA doesn't regulate eyewear because they aren't marketed as a medical device and because they are so new, there haven't been many studies done on  their efficacy.

According to the American Academy of Ophthalmology, you don’t need any kind of special eyewear when using the computer. They also say that the blue light from digital devices does not lead to eye disease or even cause eyestrain. Rather, the problems that people complain about are simply caused by overuse of digital devices, it says.
“The symptoms of digital eye strain are linked to how we use our digital devices, not the blue light coming out of them.”

Can I wear blue light blocking glasses all day?

Again, there hasn't been any safety study done on wearing blue-light blocking glasses all day and if you were to read the reviews of some verified purchasers, they report no adverse effects from wearing them for the whole day.

That being said, as we wrote above, there are known positive effects of blue-light such as boosting alertness, mood, regulating the sleep-cycle and also preventing short-sightedness. It therefore stands to reason that we shouldn't wear blue-light blocking glasses all the time but rather only when we will be facing digital device screens for extended periods of time.
