I am so excited about the new iPhone blue light filter update! We finally have a night time viewing setting that filters out blue light! Previously the only solution to reduce night time blue light exposure while using an iPhone was jail breaking the phone to use F.lux, but that compromises security and isn't for the faint of heart. Even turning down the brightness settings didn't change the warmth (color) of the light. But with the latest iOS release, we now have a built in solution directly in the phone's settings!
