Apple has been known to be one of the most innovative tech companies in the world today because of the fact that they do bring a lot of new and advance technology to their users. One of their biggest product is their phone lines, which has been dubbed by many as the best phone in the world.
The iPhones have great reviews from their hardware to their software. However, one of the biggest complaints that Apple gets about their iPhones is the backlight the iPhone has.
Fortunately, now, Apple has finally given action to that concern. Recently, the company has added a special backlight that, according to them, will help their iPhone users sleep easily.
The new feature by Apple was released recently in the new iOS 9.3 called Night Shift. which is available for their iPhones and iPads. The new feature "Night Shift" is backed by a study that confirmed that the blue light phones and pads emit interrupt the sleep -- more specifically the melatonin-producing function of the brain, which helps one sleep at night.
Now, through the new iOS 9.3 features, users of Apple iPhones can change the backlight of their phones during the night to cut back the harmful waves blue light emits. Blue light is used greatly in phones and pads because this light is the best out of all the lights that can show the screen clearly despite it being sunny but when it is dark the brain interprets the blue light being emitted as sunlight.
"Blue light plays havoc with your sleep by disrupting your circadian rhythms," said neuroscientist Anne-Marie Chang of Pennsylvania State University. So now, Apple has devised a way wherein the phones with the iOS 9.3 features will automatically change its backlight during night time from blue light to warmer colors such as beige and orange, and then will return again to blue light in the morning.
"What Apple is doing is very reasonable -- it's based on science. But it isn't just the light," said Dr. Phyllis Zee of Northwestern University. "The intensity matters too, so color needs to be shifted and intensity needs to dropped," added Dr. Mariana Figueiro.
