The upcoming Apple iOS 9.3 beta will be including a "Night Shift" mode that automatically switches the screen's display from blue to yellow light at night in order to improve the user's sleep and productivity, reported Telegraph on Tuesday.
"Night Shift uses your iOS device's clock and geolocation to determine when it's sunset in your location," noted Apple. "Then it automatically shifts the colors in your display to the warmer end of the spectrum, making it easier on your eyes."
In the effort to improve their products, tech companies are developing bigger, brighter and bluer screens, but this type of light allegedly causes a negative effect on the quality of sleep of people.
According to Scientific American on Sept. 15, 2015, blue light decreases the levels of melatonin, the sleep-inducing hormone released by the body, compared to other wavelengths, causing a change in the body's natural body clock and can lead to several health issues.
Blue light was also found to increase the alertness level of a person, keeping one more awake even at bedtime.
"Many studies have shown that exposure to bright blue light in the evening can affect your circadian rhythms and make it harder to fall asleep," Apple said.
Other features that Apple will be including in their new iOS will include a revised version of the News and Health apps, as well as the ability to lock the Notes app with the user's fingerprint or a numerical code.
The company also improved its education offering system through a multi-user support for mobile devices, noted The Guardian on Tuesday. Schools offering the use of an iPad in the classroom setting can now allow students to access their own materials by logging in.
Developers who have downloaded the new iOS 9.3 beta can now enjoy the "Night Shift" feature, which is yet to be available to the public, with no details on the release date.
