Does Night Light on Mobile Really Work? In fact, the principle of the eye protection mode of the hand is very simple, that is, by turning the phone yellow and darkening the mode, the color temperature of the screen changes, from the original cold light to warm light, and the yellow tone of the screen is increased. In this way, you won't feel particularly dazzling when looking at the phone, which can relieve eye fatigue to a certain extent, but if you want to rely on this mode without controlling the time you use the phone, changing the distance between your eyes and the phone, etc., the screen is still very harmful to your eyes.

After a long screen view, do you need eye drops to relieve dry eyes? This is caused by the rapid evaporation of the tear film on the surface of the eyeball and the instability of the tear film, although such uncomfortable symptoms do not cause blindness, but prolonged dry eyes are easy to develop into dry eye syndrome. If you suddenly find that your eyes are red, swollen, stinging, and blurry, this is because playing with your mobile phone in a dark environment will make your pupils dilated and cause the outlet of aqueous humor to be blocked, and when the aqueous humor cannot be discharged, the intraocular pressure will rise, increasing the risk of glaucoma, please seek medical attention in time.

In fact, the best "eye protection mode" is our own. When using electronic devices, consciously control the distance, not too close, try to set aside a certain amount of time at work, relax our eyes, and pay attention to the combination of work and rest; When you feel uncomfortable in your eyes, stop what you are doing, choose to look into the distance or rub our palms to relieve it with a warm compress; In the process of commuting, don't keep staring at your phone, at this time, put down your phone and enjoy the scenery along the way, maybe you can find another kind of beauty; If it really doesn't work, wear anti-blue light eyes if necessary, which will also have a certain protective effect.

The so-called eye protection mode refers to the way to block blue light through the mobile phone and adjust the brightness of the screen to achieve eye protection. As long as you keep staring at the screen, no matter what eye protection mode is, it is not good for your eyes. So don't think you're done with the eye protection mode.

Mobile phone eye protection has limited eye protection. To protect your eyesight, you should reduce the time you spend on electronic products such as mobile phones and tablets, and you can wear scientific protective glasses.

Useful, eye protection mode (low blue light mode) can play a role in lowering mobile phones and tablets when turned on.

The effect of the blue light radiation ratio of the screen, the effect of increasing the peak blue light ratio of the screen, reducing the brightness of the screen, and reducing the color temperature of the screen (making the screen yellow).

The total energy of the blue light band and the peak energy of the blue light band are suppressed, thereby reducing the damage to eye health caused by harmful blue light radiation from the screen. Therefore, the eye protection mode does have the effect of reducing the harmful blue light of the screen, and it is recommended to turn it on.

Hello, I've seen your question so bad, I'm sorting out the answer now, please wait a minute or two, look at the phone for a long time, the eye damage is still quite big, it's always good to protect your eyes!

It's better than nothing, looking at your phone for a long time will definitely hurt your eyes.

The eye protection mode is not useful for sleep.

British researchers have found that the "night shift" or "eye protection" mode of most smartphones, while reducing the blue light emitted by screen lighting, is not helpful for sleep and may make it harder for mobile phone users to fall asleep.

Previous studies have shown that blue light is not only harmful to vision, but also affects the body's melatonin secretion and affects sleep quality. As a result, smartphone manufacturers have set up "Night Shift" or "Eye Protection" modes for their phones, which can reduce the amount of blue light emitted by the lighting of the mobile phone screen.

However, researchers at the University of Manchester in the United Kingdom found that blue light had a limited effect on sleep disturbances. Compared to turning on Night Shift or Eye Protection, lowering the brightness of the screen display when using your phone before bed is more conducive to sleep.

Generally speaking, in order to see objects clearly, the pupil will shrink when the light is bright, and expand when the light is dark, if the brightness difference between the ambient light and the display is too large, the pupil is in two kinds of light, it will expand and contract repeatedly, causing eye fatigue, so when using the computer, adjust the brightness as much as possible to be consistent with the ambient light.

Some mobile phone manufacturers have introduced the so-called "eye protection mode" by modifying the color temperature of the screen. Color temperature is the physical quantity that defines the color of the light source, we usually call warm light, the color temperature is lower, and the color temperature of cold light is higher.

Just by adjusting the color temperature, increasing the yellow tone of the screen, eye habits, eye distance, ambient light intensity and other factors, looking at the phone for a long time may still cause damage to the eyes. Therefore, the eye protection mode of the mobile phone does not really play the role of eye protection.

Usually you should pay more attention to the light source, the color temperature is too high or too low is not good, the light brightness should be stable and flicker-free, and the light should be soft and uniform without glare. Develop good eye habits, go to regular hospitals for regular examinations to establish refractive files, and conduct binocular vision function examinations to effectively prevent the occurrence and development of myopia.

Something is better than nothing, in fact, controlling the time you spend looking at your phone is the most effective.

In general, it doesn't work. But it's better than useless, it's much softer. Just leave it on if it's okay.

Don't look at your phone in the dark is real! It's super hurtful.

Eye Care isn't really eye protection.

The eye protection mode of the mobile phone is actually to adjust the color temperature of the screen, the color temperature of yellow light is warmer, and the blue light is reduced by increasing the warm color temperature, forming a softer yellow screen mode on the mobile phone screen.

But in fact, after testing by many institutions, the blue light will be reduced when the eye protection mode is turned on in the general smartphone, but it will not be completely eliminated, and the reduction ratio is about 30 40%.

The eye protection mode can reduce the damage of blue light to the eyes, but it is only partially reduced, we still have to pay attention to eye protection in daily life, not to turn on the eye protection mode and everything will be fine.

Minimize the duration and intensity of exposure to blue light when looking at electronic screens. It is mainly to pay attention to eye habits, eye distance, environment, light intensity and other factors.

Pay attention to cherry blossom search when using electronic products

1. According to family conditions, the priority is ultra-short throw laser TV, traditional projector, ordinary TV, desktop computer, laptop computer, tablet computer, and mobile phone.

2. When using the projector, the distance should be more than 3 meters; When using a normal TV, the distance should be more than 4 times the diagonal distance of the screen; When using laser TV, the distance is not less than 2 meters; When using a computer, the distance should be more than 50 cm.

3. Look at electronic products must follow the "20-20-20" rule, that is, after 20 minutes of electronic screens, you should look up at 20 feet (6 meters) away for more than 20 seconds.

It's useless, what really protects your eyes is to look at your phone less.

The so-called"Night Light mode"At this stage, the vast majority of manufacturers use the means of removing Blu-ray, that is, software to remove Blu-ray. Through a specific software algorithm, the blue light emitted by the screen can be reduced. Since the LED display now mostly uses RGB three-color pixels, when the blue light is reduced, the spectrum of red and green will show a color close to yellow after fusion, which is why"Night Light mode"The reason why the screen appears yellow.

This kind of software means to remove blue light has its drawbacks, first, it can only remove about 30% of blue light, and the protection of vision is limited; Secondly, the color temperature of the screen is too high, resulting in yellowish colors, and many manufacturers have darkened the screen in this mode, which has led to a serious decline in the user's reading experience in eye protection mode.
