Is the eye protection mode on the mobile phone useful?

The eye protection mode on the mobile phone is useful. After the eye protection mode (low blue light mode) is turned on, the blue light radiation ratio of mobile phones and tablet computers can be reduced, the blue light peak ratio of the screen can be increased, the screen brightness can be reduced, and the screen color temperature can be reduced (making the screen yellow);

The total energy and peak energy of blue light band are suppressed, thus reducing the damage of harmful blue light radiation on the screen to eye health.

Therefore, the eye protection mode does reduce the harmful blue light on the screen, and it is recommended to turn it on. Although the lower the screen brightness of the same electronic product, the smaller the blue light radiation, but the lower the screen brightness is not necessarily the better. When the brightness of the screen is too low, the strobe frequency may be too low, which may also cause harm to the eyes.

Extended data:

After the eye protection mode (low blue light mode) is turned on, the color temperature of the screen can be reduced (the screen turns yellow). Low color temperature light source is characterized by relatively more red radiation in energy distribution, which is usually called "warm light"; After the color temperature rises, the proportion of blue light radiation in the energy distribution increases, which is called "cold light".

Therefore, many consumers may think that the lower the screen color temperature, the smaller the blue light radiation and the better for the eyes. But in fact, the lower the screen color temperature, the better. When the screen color temperature is too different from the user's eye color perception habits, it will stimulate the retina, and the disorder or abnormality of color perception will cause eye discomfort. Being in such an environment for a long time can easily lead to visual fatigue and myopia. Therefore, the color temperature of the screen should make the eyes comfortable.
