Don’t lose your old glasses when you have new ones.

Abstract: during the regulation of human eyes, the synergistic effect of intraocular lens, suspensory ligament and ciliary body is indispensable. Like a camera, it can take pictures of objects near and far. However, the regulatory power of the human eye has a certain limit and gradually decreases with age., If people with myopia work long hours in front of the computer screen, their eyes will cry or show symptoms such as dryness, foreign body feeling and blurred vision. In severe cases, their eyesight will decline. In case of such symptoms of visual fatigue, the old glasses worn before can alleviate the symptoms to a certain extent., Why? Because when we look far away (5 meters away), our eyes basically do not need to be adjusted. But when the object is within 5 meters, it must be adjusted by the eyes to see clearly. The closer the object moves to the eye, the greater the adjustment force used by the eye, so as to see the nearby object., During the regulation of human eyes, the synergistic effect of intraocular lens, suspensory ligament and ciliary body is indispensable. Like a camera, it can take pictures of objects near and far. However, the regulatory power of human eyes has a certain limit, and gradually decreases with age. Generally speaking, when myopia patients re optometry and glasses, the degree of new glasses will be 75 ~ 150 degrees higher than that of old glasses. During optometry, the vision is determined by looking at a vision chart 5 meters away. At this time, the eyes basically do not need to be adjusted, even if the adjustment is very limited. The computer screen with a distance of 50 ~ 60 cm in front of you must be adjusted before you can see it clearly. If you often look at objects at close range and use your eyes for a long time, your eyes should be adjusted frequently, and even the adjustment system is always in a tense state, your eyes will feel uncomfortable., Therefore, wear old glasses (preferably 150 degrees lower than the new glasses) when viewing objects at close range for a long time. Due to the reduction of the degree, the adjustment force used in close range operation will be reduced, and the symptoms of visual fatigue will be significantly improved or even disappear. This method is also suitable for teenagers with myopia when reading and doing homework.,

myopic people who work long hours in front of the computer screen will have tears or dry eyes, foreign body sensation, blurred vision and other symptoms. In severe cases, their eyesight will decline. When such symptoms of visual fatigue occur, changing into old glasses worn before can alleviate the symptoms to a certain extent.

why do you do this? Because when we look far away (5 meters away), our eyes basically do not need to be adjusted. But when the object is within 5 meters, it must be adjusted by the eyes to see clearly. The closer the object moves to the eye, the greater the adjustment force used by the eye, so as to see the near object.
