While it’s a significant step in the right direction, Apple’s feature doesn’t efficiently block all blue light. A reduction in blue light triggers the body to produce more melatonin, which gradually lulls into a restful sleep. The scientific theory surrounding circadian rhythms is that our bodies take these cues from our environment – which happens to be blue light. This means that over time, our bodies will lose track of when it’s time to sleep and wake up. Scientists believe that overexposure to these harmful blue light rays can confuse and alter our body’s natural circadian rhythms. 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. Medical professionals have been prescribing and touting the benefit of blue-light reducing apps for several years. However, the result isn’t a technical reduction in blue light, but rather a filtered amber version. As electronic manufacturers are listening to doctor’s concerns about the harmful effects of overexposure to blue light, do they hit the mark with features such as Apple’s Night Shift?Īpple’s latest feature, Night Shift, uses geolocation and sunset time data to reduce the amount of blue light your device emits.
