What is blue light?

Blue light is natural light emitted by the sun. However, with the increasing presence of technologies in our daily lives, the latter is also emitted by high-tech devices, such as computers, smartphones such as the Iphone Or your TV. Blue light, especially turquoise blue light can have positive effects on humans. The negative effects come from the rather violet light. The latter can in particular damage the retina, especially in the youngest. While blue light blocking glasses are increasingly used, in the face of constant screen exposure, there are also some tips to limit it on the iPhone.

Night Shift is an internal iPhone feature that automatically adjusts screen colors to warmer tones to ease your eyes.
