Not long ago, we shared some pretty interesting statistics and information about Computer Vision Syndrome (digital eye strain), and how it’s a global condition. Since then, there have been some people who have asked us to better explain what we do. While the information has been readily available on our website, perhaps it’s time to simplify it a bit.

First, let’s make sure you fully understand Computer Vision Syndrome. Lifehacker recently posted a report directly related to a new infographic published by WhatisDryEye.com which revealed upwards of 25 million Americans suffer from symptoms of dry eye. We bring this up because CVS isn’t just about blue light and damaged retinas, but more on this a bit later. Let’s get back to the basics.

What you see above are two graphs showing visible light spectrums. On the left, you have the wavelengths you receive from the sun. On the right, you have the wavelengths you receive from an artificial source, and that massive spike of blue light at 450 nanometers is the one that has medical experts and researchers very, very concerned. Why? Because blue light is the only wavelength that penetrates your cornea and directly hits your retina. As we’ve pointed out before (such as here, here, and here), this can lead to a lot of negative effects and can damage your eyes—in extreme cases, permanently.

You’re heard us throw around the whole “patented lens technology” thing before, and the graphs you see above are why we say that. Notice something similar about the red line in the left graph when compared to the natural light graph further up? Yup, that’s right! It follows the same line as the natural light spectrum almost exactly. In the graph on the right, we tried to overlay both of the top graphs together so you can see what we mean. Now, we could easily block more blue light, but we purposefully block 65% of artificial blue light because that’s about the same level of blue light you receive from natural light which is good for your body and brain. Not only that, but we provide this coverage across the 400-450 nanometer spectrum because that’s the most damaging. Pretty cool, right?

These final two graphs tell the moral of the story (which is something else we repeatedly say): GUNNAR is the only patented computer eyewear recommended by doctors to protect and enhance your vision. And now you know—actually, now you can see why.

If you’d like to learn more, we delve into greater details on our website here. If you’re looking to protect your eyes so you can work and play harder and longer, purchase your very own pair of the new Cypher or Trooper.

  • Does it matter which color lenses I get? I was thinking to get the amber lenses, but does it matter? I do eCommerce for a living, so I look at my MacBook Pro Retina screen all day, plus I also watch tv, and play video games. Thanks.
