Activating the dark mode (or night) in applications is, in recent times, an alternative widely used by anyone who has a smartphone by users, where the interface replaces the originally white backgrounds for black or gray. But now the question arises: Does this option have benefits for the user's vision?
Currently, most applications already come with the option to set the dark mode and the latest analyzes show that most users prefer this dark mode more than the previous white background. THE Microsoft, just to serve as an example, already allows all Office applications, even the word processor “Word”, to have this alternative.
BUT: Night Mode Messenger now reaches all users
But when it comes to really evaluating the benefits of this night mode, some questions arise: does this mode have an effect on the user's vision, does it help to consume less battery power, or is it just an aesthetic choice?
According to Spanish ophthalmologist Rubén García, speaking to the “Damn.es" says "the contrast and colors used in night mode reduce glare and help our eyes adapt better and more easily to the surrounding light, which makes us let's make less effort and read more comfortably".
The expert also recommends using the night mode in applications when using the phone at night or in low light environments, because any light that hits us at night causes “the brain stops producing melatonin, the sleep hormone”, which causes greater arousal and less drowsiness.
“THE CONTRAST AND COLORS USED IN THE NIGHT MODE REDUCE DAZZLE AND HELP OUR EYES ADJUST BETTER AND EASIER TO THE SURROUNDING LIGHT, WHICH MAKES WE EFFORT LESS AND WE CAN READ MORE COMFORTABLY”.
"The warm colors of night mode do not confuse the organism in terms of chronological time and make it easier to fall asleep than if we were looking at a device with the screen in normal mode”, adds the doctor.
Also to inform that report da American Academy of Ophthalmology (AAO) underscores the large reduction in blue light emissions that accompanies dark mode. "Although it doesn't harm vision, decreasing exposure to blue light and limiting the time and brightness of the screen can help people sleep better and feel more comfortable.”.
And talking about the subject of reducing battery consumption, a study from "AppleInsider” concludes that using this method significantly reduces the power consumption of OLED displays. In fact, it is possible to save “up to 60% battery level” in three hours of intensive use on an iPhone X.
