China Mobile believes that the "eye protection mode" of mobile phones has a certain effect, because it can filter a part of the blue light and reduce the damage of the screen to the eyes.
China Mobile points out that our eyes are very sensitive and produce different light stimulation responses to various colors. Dark gray is a color that has less effect on eye irritation. The background light of the mobile phone is a mixture of blue light and yellow light, and the "eye protection mode" relatively reduces the blue light, increases the proportion of yellow light, and can reduce the damage of the screen to the eyes.
Of course, the phone turned on the "eye protection mode" does not mean that the eyes are no longer harmed.
China Mobile said that the mobile phone's "eye protection mode" will minimize blue light, but other light will still cause some irritation and damage to the eyes. Moreover, consumers stare at the screen for a long time, which will cause the number of blinks to decrease, the stability of the tear film will become poor, and it will easily lead to the rupture of the tear film, bringing eye fatigue, dryness, cornea damage and other eye problems. Long-term eye fatigue can lead to decreased vision, dry and itchy eyes, and even dry eye syndrome.
China Mobile recommends that when consumers use mobile phones, in addition to turning on the "eye protection mode", they can also do this:
1. Adjust the font size
2. Select a large-screen phone
3, play mobile phone at night to turn on a light, and the screen brightness to 30%
4. Look at the screen for 20 minutes, look up at the distance of more than 6 meters for 20 seconds
5, try to minimize the time to play mobile phone (this is the correct posture)
