Eyes Feeling Strained? Consider Blue Light Filtered Glasses

Screens have become a huge part of our lives. We use them to guide us, work, socialize, watch shows or movies, and make memories. They’re in our possession pretty much at all times, and if we’re awake, chances are, we’re looking at a screen.

With people spending as many as 12 hours per day looking at screens, it’s understandable why eye strain may be a prevalent issue. If your eyes are feeling strained, Dr. Nicholas Rutkowski asks that you consider using blue light filtered glasses. 

In this post, we discuss how these glasses may give your eyes a little break.

What is blue light?

Sunlight contains many different shades of light rays, including red, orange, yellow, green, and blue. Together, those light rays form the sun’s “white light.” 

These light rays have varying wavelengths and energies, which can have differing effects. Rays that are closer to the blue end of the visible light spectrum have shorter wavelengths and more energy. This can be beneficial during the day, as blue light can boost reaction times, mood, and attention. At night, however, it’s not as helpful.

Exposure to light suppresses melatonin, a hormone that helps regulate sleep patterns, and blue light does so more powerfully. We’re all guilty of browsing social media right before going to sleep or even bringing our phones to bed with us. Blue light filtered glasses can help prevent disrupted sleep patterns that could come as a result of late-night screen time.

Blue light also contributes to digital eye strain, or computer vision syndrome. This is a common occurrence, considering how many hours per day we tend to look at our screens. Computer vision syndrome occurs because our eyes and brains have a harder time interpreting characters on a computer rather than printed characters, due to lesser contrast and definition. 

What you can do

The prevalence of screens in our daily lives won’t be going away, so what can you do to keep your eyes from feeling strained? The 20-20-20 rule is a great way to prevent eye strain: Every 20 minutes, look at something 20 feet away for 20 seconds. This helps your eyes relax after looking closely at screens. 

It’s also important to make a conscious effort to blink. People typically blink 15 times per minute. However, that number drops to about five to seven times per minute while looking at screens. No wonder your eyes are strained!

In addition to blinking and using the 20-20-20 rule, consider getting blue light filtered glasses. Proper computer eyewear reduces strain and therefore increases comfortability and productivity while using computers and other digital devices. You may even find that you’re getting better sleep after using the blue light filtered glasses.
