Black and white mode can prevent blue light,
Achieve the purpose of eye protection.
Is there really such a good thing as killing two birds with one stone?
Reporter measured
Turn on black and white mode
The mobile phone world is automatically black and white
According to the prompts of netizens, the Modern Express reporter adjusted the Huawei mobile phone to developer mode, opened the simulated color space, adjusted to a total color blind mode, and the mobile phone screen instantly became a black, white and gray world. The color app icon becomes black and white; the photos in the album are automatically added with black and white filters; and a short video is randomly clicked, like watching black and white TV. Similarly, in the accessibility features of Apple's mobile phones, the color filters are adjusted, and the display effect of the mobile phone is the same.

This is different from the dark mode, the phone in the dark mode only changes the base color to black, and the icons, photos, and videos are still displayed normally. When it was readjusted back to its original mode, the mobile world was back in vivid colors.
However, the black-and-white mode is only the display effect on this phone, using this phone to take pictures, take videos, share photos, videos, others still see color.

But there are also people who encounter various problems, "open the takeaway can not see who is delicious and who is bad", "when entering the subway suddenly thought (health code) green code is black and white "...

Can the phone be black and white to prevent blue light?
Gu Zheyao, attending doctor of the Department of Ophthalmology in the North District of Suzhou Municipal Hospital, said: "After adjusting the mobile phone screen to a black and white display mode, bright blue light will still be emitted. Moreover, the black-and-white mode and the non-black-and-white mode should be exactly the same amount of blue light emission, so the method of adjusting to the black-and-white screen is completely a pseudo-method that can only achieve the surface phenomenon. "
She further explained the reasons for this, as one of the three primary colors of natural light, blue light is the shortest wavelength, the highest frequency of high-energy light, is widely used in LED technology to improve the quality of electronic products such as TVs and mobile phones. Blue light can penetrate the cornea and lens to the macular area of the fundus, causing damage. The macular area under the eyes is the place where people see things most acutely.
There are also studies that show that only by looking at the phone for a long time for 8 to 10 hours a day, the blue light generated by electronic devices will cause damage to the eyes. For teenagers, they need to pay more attention to using their eyes at close range and controlling the time spent using electronic products such as mobile phones and iPads.
She also said that the energy of blue light produced under natural light conditions is much more than that of electronic products such as mobile phones and computers, so people should also try to choose anti-blue light glasses or sunglasses in outdoor environments.
Why does a phone that is switched to black and white mode make people "head down"?
Gu Zheyao told the Modern Express reporter that this is related to the human brain. The brain is very sensitive to bright colors and is more easily attracted to the past. If everything becomes gray, even the most fun game screen will become boring, so the desire to play mobile phones will also decline.

Can I turn on Dark Mode to protect my eyes?
Now, many brand mobile phones have introduced the function of dark mode, known as the benefits of staying up late mobile phone party. There are also many people who also drive cool dark mode during the day. Gu Zheyao said that when we use our eyes, we must start from our own feelings and comforts to avoid the contrast between the screen and the environment.
A black background should not be used in a bright environment, and a large white background should not be used in a darker environment. For example, in the outdoor of the sun, indoors at night is more bright light illumination environment, the use of black background mode will feel that the eyes are very tired visually, very difficult to see, which will also lead to excessive pressure, and even dizziness.
In the same way, the adjustment of the size of the pupil of the human eye is based on a wide range of environmental colors, in a darker environment, the pupil of the human eye will be enlarged into the amount of light is sufficient, at this time the use of a large white background will be very dazzling, very easy to fatigue.
Can anti-blue light films really prevent blue light?
Gu Zheyao said that most of the films with anti-blue light functions can indeed play a role in reducing the blue light radiation ratio of mobile phone and tablet screens, improving the peak blue light ratio of screens, and reducing the color temperature of the screen, but the effect is not too obvious.
Now many mobile phones have also introduced an eye protection mode, that is, by reducing the color temperature of the screen to achieve the effect of low blue light. In addition, some scholars have found that the anti-blue light film is not as significant as the inhibition effect of low blue light mode on the harmful blue light of the screen.
