Apple recently released some new products with new features. Among these were a new iPad Pro and a new iPhone. These products come with many features, one of which is a new lighting technology called “Night Shift”. “Night Shift” changes the lighting on the phone to produce less blue light so as to help users go to sleep easier. But will it really work? Dr. Goodfellow explains.
