Since its establishment, GUNNAR Optiks has shared that blue light emitted from digital devices slows production of natural melatonin. The wavelength of blue light from digital devices matches that of the blue light from the sun. As the sun rises in the morning, your brain senses the increase of blue light and lowers the amount of melatonin produced, telling your body to wake up. Introducing blue light from artificial sources disrupts this process. As people around the world connect to digital devices regularly, and for extended periods, cases of sleeping disorders rise. Turns out, tricking your brain with unnatural blue light causes problems. Go figure!
Why Blue Light?
Perhaps in reading the above description you asked yourself, “wouldn’t any color of light effect you this way?” Certainly, when any light shines on your face you will likely wake up. However, what we are talking about here goes a little deeper. Any light shining in your face might wake you up in the morning, but only certain types of light shined into your eyes will disrupt sleep after.
An article recently posted on Gizmodo.com sheds greater light (forgive the pun) on the negative effects of blue light. Gizmodo summarized a recent sleep study done by a group of medical experts in the UK. As they put it, “short-wavelength-enriched light (blue-enriched) is likely [of any type of light] to cause the most disruption, as it most effectively suppresses melatonin and increases alertness.”
As we suggested in the beginning of this post, the wavelength of blue light is key. Light, in all its colors, travels in waves. Different colors move at different frequencies. Certain colors affect us differently. Their wavelengths cause the different effects. Blue light leads to more wakefulness, whereas red and yellow lights affect us more neutrally.
Light Bulb Example
Think, for example, of the difference between old fashioned yellow light bulbs, and florescent tubes. Yellow light naturally relaxes, particularly when compared to florescent light. When you go home you want an environment of relaxation. Given this fact, we generally prefer the softer, warmer light of yellow light bulbs. At work, however, alertness, and productivity rule. Thus, the harsher, colder light of florescent tubes generally do the trick.
The sun, in this example, does the work of florescent tubes in the morning and throughout the day, and the yellow bulbs in the evening and at night. Nature knows what we need! Imagine if the sun decided to shine like it was 9 AM at 9 PM. Sounds unpleasant and hard to sleep, right (our sympathy to our friends living way up north)? Staring at a device emitting blue light right before bed essentially does this. The difference? We choose it! We call it “relaxing.” In reality, we wreck our sleep cycle, and put our health at risk.
For years psychologists have studied the effects of colored rooms and how they can influence your mood, and it’s great to see the an increasing number of studies being done in the digital realm. Protection is important, and GUNNAR glasses are the only doctor-recommended eyewear that can provide that for you. Click here to learn more!
