How to improve the accuracy before optometry?

Abstract: when a normal person works at a close distance for a long time, and then looks at the distance, he will find that he can’t see the distant object clearly. At this time, his eyes are in a short-term myopia state. At this time, if he goes to optometry, the result is often myopia., Many people have vision problems for one reason or another and need optometry. Many people think that as long as they want optometry, they can have it directly. They do not consider the state of the body, especially the eyes at that time. However, whether the test items related to the human body are accurate or not is directly related to the state of the human body at that time. Correct practices help to improve accuracy or make detection easier, so as to maximize the reliability and accuracy of data., If you don’t hold your urine before doing routine B-ultrasound, it will affect the clarity of B-ultrasound imaging, which is easy to cause misdiagnosis or missed diagnosis. This is the necessary preparation before routine B-ultrasound. The same is true for optometry. In order to test the degree accurately, there are requirements for the state of the eyes before optometry, so some necessary preparations need to be made before optometry., As we all know, human eyes are like the most sophisticated camera. This “camera” could have focused automatically to make the image clearer, but some factors limit this function. The process of optometry is equivalent to using optical means to solve the imaging problem. The actual operation is to detect what degree of lens is added in front of your eyes to make the image clearer., In theory, the human eye is a camera, but the human eye is a living tissue after all. Whether normal people or people with vision problems, their eyes show different refractive states at different times. For example, when a normal person works at a close distance for a long time, and then looks at the distance, he will find that he is not clear when looking at distant objects. At this time, his eyes are in a short-term myopia state. At this time, if he goes to optometry, the result is often myopia, but the myopia state at this time does not represent the true degree of his eyes. Strictly speaking, optometry will cause wrong results. Therefore, before optometry, we should not work and study closely for a long time, including reading and writing. Here, I would like to emphasize the problem of low headed people playing with mobile phones. Playing with mobile phones for a long time will not only affect the accuracy of optometry, but also one of the main incentives for the instability of power in adulthood and the rise of myopia., Here we should also emphasize one kind of people, that is, people who sleep for a long time, don’t get up at dawn in the morning, and go to optometry after sleeping until noon. At this time, the cornea of the eyes is generally in a state of edema, which will also cause inaccurate optometry.,
