How Blue Lenses Can Help with Digital Eye Strain

February 28, 2021

Blue light is all around us. Our main source of it is the sun, which produces natural blue light that causes the sky to look blue on bright, sunny days. Many people think that any sort of light exposure is bad for our eyes, but this isn’t the case. Our bodies benefit from some blue light each day and getting enough has several positive effects including regulating our circadian rhythm (sleep-wake cycle), improving our mood, and boosting our memory and other cognitive functions.

 

Nevertheless, blue light isn’t only emitted by the sun. Our digital devices also emit artificial blue light that can reach our eyes and, since we spend more time using digital devices than ever before, the amount that we are being exposed to is also rising. Unfortunately, overexposure to blue light has been shown to have several negative effects, including contributing to digital eye strain.

 

What is Digital Eye Strain?

 

Digital eye strain, also known as computer vision syndrome, is a term used to describe a group of eye and vision-related problems that occur because of prolonged use of digital devices. This includes computers, tablets, smartphones, and e-readers. Looking at a screen for long periods of time requires the eyes to work harder than they do usually. This is due to a combination of factors, including the distance of the screen from your eyes, any glare or lighting issues, the contrast of colors, and more. Even if you wear glasses or contact lenses, unless you have special computer glasses, it’s unlikely that they provide optimal vision for digital device use.

 

What are The Symptoms of Digital Eye Strain?

 

There are a range of symptoms associated with digital eye strain. These include, but are not limited to:

 

  • Headaches
     

  • Blurred vision
     

  • Dry eyes
     

  • Neck pain
     

  • Shoulder pain
     

  • Muscle spasms in the neck, shoulder, or back

     

These symptoms may come and go, fluctuate in severity, and occur alone or alongside others.

 

How do Blue Light Lenses Help with Digital Eye Strain?

 

Blue light lenses, also known as blue light glasses and blue light blocking glasses, are unique in that they are designed specifically to reduce the amount of blue light that reaches your eyes. The lenses themselves contain special filters which help to prevent them from entering your eye and causing damage. And they do this with considerable success. Studies have shown that the sales of blue light blocking lenses has risen significantly over the last few years, as people spend more and more time in front of digital devices.

 

Not only can blue light lenses help to prevent any potential damage and counteract the symptoms of overexposure to blue light, but many people also who wear the glasses find that doing so makes it more comfortable to use screens for prolonged periods. It’s thought that wearing blue light lenses in combination with other techniques for reducing digital eye strain – such as taking regular screen breaks, positioning your devices carefully, and using artificial tears – can greatly improve comfort levels in people who spend a lot of time using digital devices.
