These days, f.lux users can tailor it more specifically to their unique schedules. Soon after rolling out the first iteration of f.lux, Herf wrote new code to make it respond automatically to the user’s local sunrise and sunset. “Customers told us this was something that was on their mind-that they were worried about using their tablets or mobile devices to read in bed-so we started to dig deeper.”Īs our understanding of light exposure has evolved, so has the tech. “We’ve been keeping an eye on nighttime reading for more than a year,” he says. The underlying tech-blue light that fades into orange light as the day wanes-is a direct response to a large and growing body of evidence that suggests late-night exposure to artificial light can disrupt your body's circadian rhythms, light-triggered physiological changes that regulate bodily functions ranging from sleep to metabolism.Īpple declined to talk to WIRED about Night Shift, saying that it’s still in development, but Aaron Bromberg, senior manager of product management for Amazon Devices, says the feature was created in response to customer feedback. The new feature lets nighttime users dim the amount of blue light that comes off the Fire’s screen, in favor of a mellow, amber glow.Īpple’s feature technically doesn’t exist yet, but the point of it, and Blue Shade, is simple: to let us get some sleep. Last month, Amazon released a similar feature, called Blue Shade, in an OS update for its Fire reading tablets. In a recent preview for iOS 9.3, Apple teased a new feature called Night Shift that does exactly this, automatically altering the color of your screen display to make it orange-colored in the evening.

It will rise and shine brightly in the morning, and set and dim its lights as the day winds down.

In the not-so-distant future, your personal tech will behave like the sun.
