The feature in question refers to a display setting within the Kindle application on devices running the Android operating system. This setting inverts the color scheme, presenting light text on a dark background, as opposed to the standard dark text on a light background. An instance would be activating this setting on a Samsung Galaxy tablet to read an e-book with reduced glare.
The significance of this inverted color scheme lies in its potential to mitigate eye strain, particularly in low-light environments. It achieves this by reducing the overall amount of blue light emitted from the screen, a factor associated with sleep disruption and visual fatigue. Historically, this functionality became increasingly sought after as users spent extended periods reading on digital devices, prompting developers to incorporate this user-centric design element.
