The dark mode is not as good for your eyesight as previously thought

The dark mode is one of the new internet trends, almost all applications are adapting their interfaces to this darker style. Users demand this change promoted by the different advantages that this design supposedly brings. 

From Apple to all Google applications, through social networks like Twitter, developers strive to adapt their applications and websites with a darker background that would be healthier for our eyesight and the battery of smartphones, but to what extent is it true that the dark mode is good for the health of our eyesight?

According to the statements that circulate through the network as if they were backed by a scientific base, dark tones reduce the intensity of light that our eyes must withstand when looking at the screens of the mobile or computer and that would make us blink less. 

The human eye blinks about 15 times per minute on average, except when it is in front of a screen emitting an intense light, in this case, the flickering can be reduced up to 3.6 times increasing the dryness of the eye. According to the American Optometric Association, this results in symptoms such as headaches and blurred vision. 

The solution, however, is not the dark mode. The Wired collects the statements of Anna Cox, professor of human-computer interaction at University College London, who says she doesn’t know any scientific evidence that supports the idea that the dark mode reduces eyestrain. 

The excessive effort of our eyes when looking at a screen would also is related to the intensity of the luminosity, the hours we are exposed to it and the amount of light around us. 

Better reduce brightness and activate night mode

This means that all those of your eye health should also reduce the hours spent in front of the mobile or the computer, ensure that there is enough ambient light around it so that the screen is not the only point of light and that the brightness intensity It is regulated with the environment. It would also be advisable to use artificial tears from time to time to rehydrate the eyes.

For those moments in which we have less ambient light, such as at night when we go to bed , it  would be more advisable for health to resort to the night modes that we find in the devices and replace the most damaging blue-white light with orange tones that would avoid that permanent waking effect that would be attacking our ability to have more restful hours of sleep. 

Its effect on battery life

The night mode helps us save on battery, this statement is true, but halfway. It depends mainly on the type of screen we have. In the case of mobile phones with OLED screen, the benefit is significant. 

OLED screens are able to illuminate each pixel independently so they have more real black tones and this implies that they are really reducing the effort the blacker there is on the screen. However, LCD screens have an older technology that does not have that advantage and although half of the screen is shown in black, those pixels are also illuminated and do not save as much with the dark mode.

It is not that the dark mode is not positive, it depends on the tastes of the users and what we find most comfortable to read, but it is important to keep in mind that it is not the only factor to consider when we want to protect our eyes from the effects of the continued use of the mobile.
