If the brightness of your mobile phone is not adjusted properly, it will really hurt your eyes! Have you chosen the right screen brightness?

In daily life, we are almost inseparable from electronic devices. The screens we face most often are either mobile phone screens or computer screens. When using these electronic devices, many people overlook a small setting, which is "screen brightness". In fact, whether the screen is too bright or too dark, it is easy to hurt the eyes. So, what is the appropriate screen brightness? How to minimize the damage to the eyes caused by mobile phones? Let's find out together!

Looking at the phone like this really hurts your eyes!

1. Put a "privacy screen protector" on your phone

The principle of the privacy film is similar to that of "venetian blinds", which controls the viewing angle through the parallel grating structure - at different angles, you can see completely different things, which can prevent others from peeking at the screen. But at the same time, it will significantly reduce the brightness of the phone screen.

Although there is no direct research on the relationship between privacy films and eye damage, we should still be vigilant.

When you need a high-brightness screen, the privacy film hinders the change of brightness. It can't be bright enough when it should be, and you have to adapt to it, which can easily make your eyes more tired. You really have to be careful when using privacy films.

2. Viewing the phone in a dark environment

In a dark environment, the pupils of a person will naturally dilate. After the pupils dilate, the clarity of vision will decrease, and the eyes will become more "fragile".

At this time, if you turn on a bright screen, your eyes will not be able to adjust, which will further deepen your visual fatigue and even induce glaucoma and macular degeneration. So if you want to play with your phone or watch TV before going to bed, remember to turn on the lights.

What is the correct way to use your mobile phone?

Keep your sitting posture and look at the phone as level as possible to keep your eyes relaxed. The distance between your eyes and the phone should be about 30 cm to 70 cm, and 50 cm is generally appropriate.

Set the "screen brightness" of your phone properly and adjust it appropriately according to the brightness of the environment and your eyes' perception of light. When using your phone under normal lighting conditions, it is best to keep the brightness of your phone at around 50%. Generally, it should not exceed 70% or be lower than 30%. If you are in a low-light environment, it is recommended that you adjust the phone to a dark background or turn on night mode directly.

Tips for eye protection

When working or studying, long-term use of the eyes can easily cause eye fatigue. In addition to eye exercises, what other simple and convenient ways to protect the eyes are there? For example, the "202020 rule", that is, after using the eyes at close range for 20 minutes each time, look into the distance 20 feet (6 meters) away for at least 20 seconds. This method can effectively relieve eye fatigue. It is also applicable to teenagers and children. It is recommended that the younger the age, the more you should adhere to this "rule"!
