视疲劳预防：从技术到视觉

视疲劳是指由于观看显示器或其他显示设备产生的视觉困难、眩晕、疲劳等不适症状。视疲劳的成因是多方面的，其中包括人的生理特点和心理状态，显示器的技术性能，以及人与显示器之间的交互方式。

视疲劳的预防需要从人、技术和视觉三个方面入手。首先，在人的生理特点和心理状态方面，要使用户保持良好的姿势，避免长时间的直立或低头，保持呼吸规律，避免疲劳；其次，在显示器的技术性能方面，要求显示器具备良好的视觉质量，如：分辨率、亮度、对比度、色彩等；最后，在人与显示器之间的交互方式方面，应尽量避免长时间的直视，并在使用显示器时适当休息。

总之，视疲劳的预防需要人、技术和视觉相结合，这样才能有效地避免视疲劳的产生。

Visual fatigue prevention: from technology to vision

Visual fatigue refers to visual discomfort, dizziness, fatigue and other discomforts caused by watching monitors or other display devices. The causes of visual fatigue are many, including human physiology and psychological state, technical performance of monitors, and the way humans interact with monitors.

The prevention of visual fatigue needs to be started from three aspects: human beings, technology and vision. First of all, in terms of human physiology and psychological state, users should keep good posture, avoid standing or looking down for a long time, keep regular breathing, and avoid fatigue; secondly, in terms of the technical performance of monitors, monitors should have good visual quality, such as: resolution, brightness, contrast, color, etc.; finally, in the way of human-computer interaction, we should try to avoid long-term staring, and take a break when using monitors.

In a word, the prevention of visual fatigue needs the combination of human, technology and vision, so as to effectively avoid the occurrence of visual fatigue.
