电脑显示器与视觉健康：如何保护眼睛免受屏幕伤害

随着科技的飞速发展，电脑显示器已经成为我们日常生活和工作中不可或缺的一部分。然而，长时间面对电脑屏幕可能会导致眼睛疲劳、干涩、视力下降等视觉健康问题。因此，了解如何保护眼睛免受屏幕伤害变得尤为重要。 一、调整屏幕亮度与对比度 调整电脑显示器的亮度和对比度是保护眼睛免受屏幕伤害的关键。屏幕过亮或过暗都可能使眼睛过度劳累。理想的屏幕亮度应调整为与环境光线相匹配，避免过于刺眼或过暗的情况。此外，适当调整对比度，使得屏幕显示更加清晰，有助于减轻眼睛的负担。 二、保持正确的坐姿与距离 正确的坐姿和距离对于保护眼睛健康同样重要。应保持身体与屏幕的距离在50-70厘米之间，避免过近或过远。同时，保持直立的坐姿，使眼睛与屏幕保持水平，以减少颈部和背部的压力。 三、定期休息与远眺 长时间盯着电脑屏幕会导致眼睛过度疲劳。因此，定期休息并远眺有助于缓解眼睛疲劳。每隔20分钟左右应将视线从屏幕上移开，看向远处或绿色植物，使眼睛得到充分的放松和休息。此外，在连续工作一段时间后，应进行适当的眼部运动或眼保健操，以促进眼部血液循环，缓解眼部疲劳。 四、使用防蓝光眼镜或软件 防蓝光眼镜或软件可以有效减少蓝光对眼睛的伤害。长时间使用电脑会使人暴露在大量的蓝光中，而蓝光可能导致视网膜损伤和眼疲劳等问题。使用防蓝光眼镜或软件可以减少蓝光的暴露量，降低眼疲劳的风险。 五、合理调整工作环境与氛围

保持良好的工作环境和氛围也有助于保护眼睛免受屏幕伤害。例如，保持室内光线充足且均匀分布，避免在光线过暗或过亮的环境下使用电脑。此外，定期开窗通风，保持空气清新，有助于减轻眼部疲劳和不适感。

英文翻译： Computer Display and Visual Health: How to Protect Eyes from Screen Injuries With the rapid development of technology, computer displays have become an indispensable part of our daily lives and work. However, prolonged exposure to computer screens may lead to eye fatigue, dryness, decreased vision, and other visual health issues. Therefore, it is crucial to understand how to protect our eyes from screen injuries. Firstly, adjusting screen brightness and contrast is key to protecting eyes from screen injuries. Screen brightness that is too bright or too dark can cause eye strain. The ideal screen brightness should match the environmental light to avoid being too glaring or too dark. Additionally, adjusting the contrast appropriately to make the screen display clearer can help reduce the burden on the eyes. Secondly, maintaining correct sitting posture and distance is also important for protecting eye health. It is necessary to keep a distance of 50-70 centimeters between the body and the screen, neither too close nor too far. At the same time, maintain a straight sitting posture so that the eyes and screen are level, reducing pressure on the neck and back. Thirdly, regular breaks and distance gazing can help alleviate eye fatigue. It is recommended to take a break from the screen every 20 minutes or so and look away into the distance or at green plants to give the eyes a full relaxation and rest. Furthermore, after working for a while, perform eye exercises or eye massages to promote blood circulation in the eyes and alleviate eye fatigue.

Fourthly, using anti-blue-light glasses or software can effectively reduce the harm of blue light to the eyes. Long-term use of computers exposes people to a large amount of blue light, which can cause retinal damage and eye fatigue. Using anti-blue-light glasses or software can reduce exposure to blue light and lower the risk of eye fatigue. Lastly, adjusting the working environment and atmosphere reasonably can also help protect eyes from screen injuries. For example, maintaining sufficient and evenly distributed indoor light, avoiding using computers in dark or overly bright environments. Additionally, regularly opening windows for ventilation and keeping the air fresh can help alleviate eye fatigue and discomfort.
