What's the Big Deal with Blue Light?


    Most people know about the effects of Ultra-Violet light -- we can all remember summer days filled with uncomfortable sunburns. But, the effects of Blue Light waves, specifically on our eyes, is less commonly known. According to an article published by Harvard Medical School, “Blue wavelengths—which are beneficial during daylight hours because they boost attention, reaction times, and mood—seem to be the most disruptive at night.”

    Effects of Blue Light

    Blue light (or HEV light) has always been around us. But the more we're in front of Digital screens, the more we expose ourselves to its damaging effects, like fatigue, headaches, and disruptions to healthy sleep patterns. As previously stated, blue light does help stimulate us, which can be helpful in regards to productivity, attentiveness and focus. The downside is that without aid, you can’t effectively minimize the stimulus while using most technology, which can throw off your daily rhythm. This added stimuli can cause disruptions with your sleep, because your mind might find it difficult to settle down and decompress — throwing off your circadian rhythm. According to the National Sleep Foundation, your circadian rhythm or cycle is described as “a 24-hour internal clock that is running in the background of your brain and cycles between sleepiness and alertness at regular intervals.”

    More specifically, exposure to blue light at night slows down the production of melatonin — the chemical that tells your brain it’s time to sleep. The Mayo Clinic describes melatonin as “a hormone in your body that plays a role in sleep. The production and release of melatonin in the brain is connected to time of day, increasing when it's dark and decreasing when it's light.”   Putting it simply, blue light confuses your brain into thinking it’s daytime when it’s not. So the natural production of melatonin that happens at the end of the day is thrown out of alignment. When the effects of blue light versus green light waves were compared, it was concluded that the blue light wave suppressed melatonin almost twice as long as the green light.

    Symptoms of Prolonged Blue Light Exposure 

    It’s hard to conclude what all of the long term effects of extended screen time are. This is mainly because Millennials are the first generation with such high rates of digital exposure. But, we do know that some of the immediate effects are —

    • Tired, heavy eyes
    • Headaches
    • Trouble falling asleep and staying asleep
    • Blurred vision
    • Dry eyes

    All of these symptoms, at a minimum, are uncomfortable and a hindrance to daily productivity.
