    Not All Blue Light Is Bad

    So, is all blue light bad for you? Why not block all blue light, all the time?

    Bad idea. It’s well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood.

    In fact, something called light therapy is used to treat seasonal affective disorder a type of depression that’s related to changes in seasons, with symptoms usually beginning in the fall and continuing through winter. The light sources for this therapy emit bright white light that contains a significant amount of HEV blue light rays.

    Also, blue light is very important in regulating circadian rhythm the body’s natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night can disrupt this cycle, potentially causing sleepless nights and daytime fatigue.

    Does Apples Night Shift Feature Block Blue Light

    As electronic manufacturers are listening to doctors concerns about the harmful effects of overexposure to blue light, do they hit the mark with features such as Apples Night Shift?

    Apples latest feature, Night Shift, uses geolocation and sunset time data to reduce the amount of blue light your device emits. However, the result isnt a technical reduction in blue light, but rather a filtered amber version.

    Medical professionals have been prescribing and touting the benefit of blue-light reducing apps for several years. It just so happens that Apple finally listened to their science-driven crowd that wanted a solution to absorbing bright light well into the evening hours.

    Scientists believe that overexposure to these harmful blue light rays can confuse and alter our bodys natural circadian rhythms. This means that over time, our bodies will lose track of when its time to sleep and wake up. The scientific theory surrounding circadian rhythms is that our bodies take these cues from our environment which happens to be blue light. A reduction in blue light triggers the body to produce more melatonin, which gradually lulls into a restful sleep.

    While its a significant step in the right direction, Apples feature doesnt efficiently block all blue light. While any reduction in the intensity or duration of blue light is helpful, its important that people look to other means to protect their baby blues.

    How Effective Are Blue Light Blocking Apps

    Unfortunately, they dont work as a proper filter. Their lack of efficiency is due to the fact that they can only reduce the blue light instead of filtering or blocking it.

    Why do we need proper filters to protect our eyes from blue light exposure? Because ALL screens have this problem called backlight bleeding which means your monitor will still bleed light from the backlight and around the edges. That excess light isnt picked up by f.lux, Night Shift or any other blue light apps as they are essentially offering a software solution to a hardware problem.

    The problem is that these apps cant eliminate but only reduce blue light exposure. Therefore, your eyes can still get strained when you use these blue light filtering apps.

    Unfortunately, thats not the only problem weve identified with blue light filter apps. Blue light is not only released by our smartphones and computers, but also by our TVs and all sources of artificial light.

    While these apps are certainly a step in the right direction, it definitely falls short to solve the problem completely. In fact, this study indicates that less than 1 lux of monochromatic light elicited a significant suppression of nocturnal melatonin.

    To reevaluate your lighting strategies is no longer an option but a necessity to ensure maximum health.

    How Does The Apple Night Shift Blue Light Filter Work

    10 Best Blue Light Filter Apps For Android to Protect Your ...

    To activate the Apple Night Shift feature on your device, the process is pretty simple:

    • Access the Settings feature on the phone,
    • Navigate to Display and Brightness
    • Turn on the Night Shift mode
    • Then, Shift the colors from less warm to warmer. The warmer the setting, the less blue light your device will emit resulting in less sleep interference.

    Sounds plausible. However, when 12 young adults were recruited for a study to test it out, the results were less than promising.

    The study examined three different settings on the iPad:

    • Night Shift disable,
    • Night Shift warmer,
    • Night Shift less warm.

    Although the Night shift mode did make some difference, the results showed that all three settings suppressed the melatonin production, rather than regulating it. No wonder it was causing such a buzz!

    Why such disappointing results?

    Its not the light’s color spectrum that affects sleep its its brightness. Although the Night Shift blue light filter was making the screen color warmer, it didn’t tone down its intensity, which was precisely the cause of sleep disruption. As a result, the blue light filter was virtually useless in helping users restore their natural sleep patterns.

    The Apple Night Shift blue light filter is not the only blue light filter out there with questionable results in their effectiveness in blocking blue light. You might have heard of F.lux as well. You can discover more about its effectiveness here.
