Effect of electronic equipment on eyes
In today's digital era, electronic equipment has become an indispensable part of our life. However, the use of electronic devices has a great impact on the eyes. This article will elaborate from several aspects, such as vision decline, dry eye, asthenopia and myopia development, to help people better understand and prevent these problems.
Impaired vision
Long term use of electronic equipment will lead to decreased vision, especially in low light environment. The screen of electronic equipment emits light through blue light, and long-term exposure to blue light will cause retinal damage. In addition, staring at the electronic device screen for a long time will make the eye muscles tense for a long time, which is easy to lead to eyestrain and visual defocus.
In order to prevent vision loss, we can take the following measures. First, keep a sufficient distance from the screen of the electronic equipment and try to keep a safe distance. Secondly, follow the 20-20-20 rule - look at objects 20 feet (about 6 meters) away every 20 minutes for 20 seconds. This can effectively relieve eye tension and prevent vision loss.
xerophthalmia
Using electronic equipment for too long is likely to cause dry eye. The radiation from the electronic screen will evaporate the water on the surface of the eyes, causing dryness, pain and blurred vision. In addition, looking at the electronic device screen for a long time will make people forget to blink, further aggravating the problem of dry eyes.
The way to prevent dry eye is simple, but it is very important. Measures such as maintaining good indoor humidity and ventilation, blinking and taking a rest with eyes closed regularly, and using eye moistening liquid to moisten the eyes can help alleviate the symptoms of dry eye.
Asthenopia
Long term use of electronic equipment can easily lead to visual fatigue. Visual fatigue is a kind of eye muscle fatigue, which can lead to eye pain, dry eyes, itching and other uncomfortable symptoms. In addition, focusing too much on the electronic device screen will reduce the adjustment function of the eyes, which will lead to blurred vision and visual fatigue.
In order to prevent visual fatigue, we can take some simple methods. Rest your eyes for 5-10 minutes at regular intervals, and perform eye relaxation exercises, such as eye movement, blinking, etc. In addition, activities away from the electronic screen can be carried out when the eyes are excessively used, such as doing some sports, walking, etc.
Myopic development
Long term use of electronic devices is an important factor in the development of myopia. When watching the electronic screen, the gaze distance of the eyes is short, and the eyes are kept away from the distant focus of the natural environment, which makes the eyes overexert, leading to the occurrence and aggravation of myopia.
In order to prevent the development of myopia, we should reasonably control the time of using electronic devices, try to maintain eye hygiene, and control the time of watching the electronic screen closely. In addition, outdoor activities are also one of the effective ways to prevent the development of myopia.
summary
The effects of using electronic equipment on eyes mainly include vision decline, dry eye, visual fatigue and myopia development. In order to prevent these problems, we need to keep a proper distance from electronic equipment, follow the 20-20-20 rule, regularly rest our eyes, and strengthen outdoor activities. Only the correct use of electronic equipment can protect eye health.
