This software function adjusts the colors displayed on Apple mobile devices, such as iPhones and iPads, to reduce the amount of blue light emitted by the screen. The intended result is to make the screen appear warmer, often with a yellow or orange tint. For example, a user activating this setting might notice that white backgrounds shift to a more beige hue in the evening hours.
The perceived benefits of reducing blue light exposure include minimizing potential disruptions to sleep cycles and decreasing digital eye strain. The introduction of such features in operating systems stemmed from growing awareness of the impact of prolonged screen usage on human health and well-being, leading to increased demand for ways to mitigate negative effects.
