What is the optimal height of the monitor to the eye?

Just look down a little bit. ~~

According to the theory of ergonomics, the contrast and brightness of the display need to be adjusted according to factors such as the use environment and the time of use. Generally speaking, for users who have been using it for a long time, it is recommended to adjust the contrast to a moderate position, which can not only ensure the display effect, but also reduce the damage to the eyes. At the same time, you can also raise your hand by adjusting the brightness appropriately to reduce the damage of radiation to your eyes.

High contrast can indeed make the image more vivid and clear, and for some scenes that require high-precision identification, such as playing shooting games, the contrast can be appropriately improved. However, too high a contrast ratio can cause damage to the eyes, so it needs to be adjusted moderately. As for PUBG, there is no scientific evidence that increasing the contrast can quickly discern enemies.

Low contrast does reduce eye damage from radiation, but it can distort and blur images, and it can also affect visual comfort and accuracy. Therefore, you need to adjust according to the actual situation to find the contrast and brightness settings that work best for you. In addition, taking regular breaks, staying away from computers, drinking plenty of water, and eating more fruits and vegetables can also reduce the damage to your eyes.

In short, for the contrast and brightness settings of the display, you need to adjust it according to the actual situation to find the most suitable setting for you. At the same time, pay attention to eye protection, rest more, exercise more, wear goggles and other methods can reduce the damage to the eyes.

Advantages of low contrast:

It is true that lowering the contrast and brightness reduces the radiation produced by the display while also reducing the rate of eye strain. Low-contrast displays are generally more eye-friendly, especially if you've been using electronic devices for long periods of time.

Disadvantages of low contrast:

In addition to the distortion and unclear images you have already mentioned, low contrast can make it difficult to distinguish between text and images, making it laborious to read and view content. In addition, too low contrast can also affect color performance, resulting in excessively flat colors and a lack of richness.

About debugging contrast issues:

Usually, the default settings of the monitor at the factory are already more appropriate. However, depending on personal preference and the environment in which it will be used, adjusting the contrast and brightness appropriately can be a ruin. Reasonable posture varies from person to person and can be adjusted according to individual needs and comfort.

On the issue of shooting games and contrast:

Turning up the contrast ratio may indeed help to spot and identify enemies more quickly, as a purely high contrast ratio can make the distinction between light and dark in the frame more visible, making the outline of the enemy more recognizable. For the game PUBG, there is some truth to this theory.

On the balance between protecting the eyes and facilitating the identification of enemies:

Finding the right balance between protecting your eyes and making it easy to identify enemies requires experimentation and adaptation to your individual's needs and comfort. The contrast can be increased appropriately, but avoid being too high to avoid unnecessary strain on the eyes. At the same time, you can also try adjusting other settings of the display, such as color temperature, brightness, etc., to find the one that works best for you.

You can have both, and the key is to make reasonable adjustments to your individual needs.

Contrast is a parameter in a display that controls the degree of difference between brightness and darkness. There is no one default contrast value that applies to everyone, as everyone has different visual needs and perceptions. However, here are some additional information to come to your question:
