I’ve been rocking the beta version of iOS 9.3 for about a week now, and the most evident upgrade to iOS 9 (and my eyes) is, without a doubt, Night Shift.
Speaking from experience...
I never realised how much of a difference light temperature made to my eyes, until I downloaded the beta version of iOS 9.3. Since I use two phones (an iPhone and an ever-changing Android phone to keep my Android senses sharp), I immediately noticed its impact.
Before falling asleep, I have the habit of checking my phones one last time, and I found myself reaching for my iPhone to carry out most of my social media duties in the dark.
I honestly don’t know if it helps me fall asleep easier (since I typically don’t have much trouble on that end), but the relief on my eyeballs was evident, as my display shifted from stark blue light to a warmer glow.
You won’t realise how blue light has been sticking pins into your eyeballs until you experience the comforting hue of a warmer light temperature. It might look like a ghastly jaundiced display right now, but experience it in darkness and it will feel like eyeball salve. Once you go Night Shift, you probably won’t be able to go back.
Night Shift offers a variety of different customisation options. Under Schedule, I've chosen to activate it from Sunset to Sunrise, so that it automatically changes from a cooler light temperature to a warmer one when night falls, based on my geolocation.
I don’t have to mess with it anymore, and it automatically shifts back when day breaks and my eyes don’t feel as fatigued by blue light.
You can also choose to switch it off completely or have it kick in at a time of your choice. Either way, definitely give it a go - your eyes will definitely thank you for it after a hard day of staring at your computer screen. In fact, if you're in bed as you read this, you'd be benefiting from it right now.
