What Are the Pros and Cons of Using Blue Light Glasses?

Posted by Jaclyn Edelstein on

On average, in the US, people spend between five to six hours on their phones on a daily basis, which still doesn’t include work-related usage.

Unfortunately, so much time spent in front of a device that emits excessive amounts of short-wavelength, high-energy blue light can negatively impact our circadian rhythm and lead to digital eye strain, headaches, and blurred vision.

The detrimental effects of blue light on our eyes have been documented extensively over the years.

Research has shown that blue light blocking glasses benefits those who wear them by protecting the eyes from overexposure to blue light by as much as 23.6 percent without reducing quality. Learn more about blue light glasses pros and cons below.

Benefits of Blue Light Glasses

Let’s begin with the blue light glasses pros and cons by delving into the benefits of blue light glasses. These benefits stem from the ample blue light protection provided by the glasses for wearers.

Blue light glasses do not actually block blue light completely. Instead, they have special filters that lessen the intensity of blue light, providing sufficient protection from the harmful effects of artificial blue light while still maintaining color vision.

Here are some of the blue light blocking glasses benefits.

Restores Circadian Rhythm

The circadian rhythm plays a significant role in keeping the body healthy by regulating our sleep-wake patterns. With a healthy circadian rhythm, the body can produce a healthy amount of hormones and regulate our sleep, giving our bodies time to recover from all the hard work it is subjected to during the day.

Natural blue light obtained from sunlight is healthy for the body as it keeps our bodies active and alert during the daytime. But at night, our bodies produce melatonin to prepare for sleep.

However, continued exposure to blue light from LED screens and other devices delays melatonin production. Through the usage of blue light filtering glasses, your body continues to produce melatonin as it should to ensure that your circadian rhythm stays constant.

Reduces Eye Strain

Blue light scatters more quickly than other colors in the visible light spectrum. Because of this scattering, it’s not as easily focused as other colors.

Continued exposure to blue light by staring at the screen on your phone, television, or computer reduces the contrast in your eyes thanks to the visual noise caused by blue light, which causes digital eye strain.

Filtering out blue light reduces visual noise, helping our eyes focus better and lessening eye strain.

Reduces Risk of Eye Diseases

Constant exposure to artificial blue light increases the risk of developing macular degeneration, a condition in your retina that distorts your central vision. This occurs because your cornea and eye lens cannot block blue light, allowing it to penetrate through your retina.

This can lead to macular degeneration-like symptoms and increase your risk of developing this condition along with other eye conditions such as cataracts.

Wearing blue light glasses reduces the risk of macular degeneration and other eye diseases by filtering blue light that passes through the eyes, providing ample protection from the harmful rays of your devices.

Improved Overall State of Well-Being

Perhaps the most significant benefit of blue light glasses is an overall feeling of wellness. As mentioned before, melatonin production on our bodies at night is crucial in helping our bodies prepare for rest.

When the body is allowed to produce a sufficient amount of melatonin, it is able to regulate various brain and behavioral processes. This results in a feeling of restedness, improving mental health and overall mood.

Disadvantages of Blue Light Glasses

While blue light glasses have numerous benefits, there are some disadvantages to these helpful accessories. Here are some of the drawbacks to wearing blue light filtering glasses:

Altered Perception of Color

Glasses that come with a blue light filter have a slight yellow tint. This is responsible for filtering out the blue light in order to reflect it back.

As you look through these lenses, you may notice that the colors of everything you see may look different, which will be more noticeable when white paint turns a slightly yellowish color. Avoid wearing these glasses while you work if it involves distinguishing colors.

Diminished Scotopic Vision

Scotopic vision refers to the ability of the eyes to see under low-light conditions. Some studies show blue light filtering lenses can decrease scotopic vision.

That means under low light conditions, it’s better to take off your glasses (you don’t need them anyway in the absence of light).

The Bottom Line

Blue light glasses offer significant protection for the eyes from harmful blue light rays cast from various devices.

When you have to deal with these devices for prolonged periods daily, it can take a significant toll on your eyes and be detrimental to your overall health.

Protect your vision and your well-being by wearing blue light filter glasses. It’s clear from our list of blue light glasses pros and cons that the benefits of wearing these glasses far outweigh the drawbacks.
