iPhones to get 'Night Shift'
Apple is going to introduce warmer screen colours for night time to make it easier on users' eyes in the next update, iOS 9.3.
The change will see the phone's screen begin to emit warmer colours during darker hours in the hope of causing less disruption when users go to sleep after prolonged use.
Typically iPhone screens emit blue light but the new feature, with assistance from the phone's clock and geolocation, will change the type of light it sends out after sunset.
"Night Shift uses your iOS device's clock and geolocation to determine when it's sunset in your location. Then it automatically shifts the colours in your display to the warmer end of the spectrum, making it easier on your eyes," Apple said.
Tech companies have placed a focus on developing screens that emit blue light in order to improve efficiencies, however, medical concerns surrounding sleep patterns and productivity have been raised. Sleep is affected by blue light as it suppresses what is known as melatonin. A hormone that encourages us to sleep at night. Other features are being touted in 9.3 including security for the 'Notes' app.
