Will Apple's Night Shift Save Our Vision?
Apple's new iOS 9.3 was just released and is packed full of new features for our iPhones and iPads. Among the new features is Night Shift, which allows users to shift the color temperature of the retina display based on the time and location of your device. This shift of color works by reducing the amount of blue light emitting from the devices screen.
Backlit devices such as iPhones and iPads emit high levels of blue-light and it has been shown that increased exposure to blue-light can have harmful affects on our body. It is commonly accepted that blue-light can affect our sleep pattern making more difficult to fall asleep after use, but blue-light may actually be a key to accelerating cataract formation and macular degeneration.
It is not yet known if Apple's Night Shift will actually reduce the amount of blue-light entering the eyes, but it is an important step to understanding the harmful affects of blue-light.
