Embodiment 1

[0038] A method of observing the development process of myopia by using the telephoto method and detection equipment, and actively guiding people to look into the distance to prevent myopia. The phenomenon that the virtual image of an object is staggered. Take the person's own arm as a middle point, and take the determined telescopic object as the telescopic point; and hold a detection device, and then guide the human eye to look at the distant telescopic point through the middle point of the arm; at this time, in the human eye A detection device that can form a certain virtual image is installed in the telescopic line of sight, and whether the eyes are nearsighted is judged by observing the imaging characteristics of the virtual image. Described detection instrument is a small shape umbrella (such as figure 1 shown). If used figure 1 As shown in the small umbrella inspection, the umbrella tips at both ends are on the same horizontal plane. Assuming that the distance betwe...

Embodiment 2

[0040] A method of observing the development process of myopia by using the telephoto method and detection equipment, and actively guiding people to look into the distance to prevent myopia. The phenomenon that the virtual image of an object is staggered. Take the person's own arm as a middle point, and take the determined telescopic object as the telescopic point; and hold a detection device, and then guide the human eye to look at the distant telescopic point through the middle point of the arm; at this time, in the human eye A detection device that can form a certain virtual image is installed in the telescopic line of sight, and whether the eyes are nearsighted is judged by observing the imaging characteristics of the virtual image. The detection apparatus is a combination of two letters of KO (such as figure 2 shown), and the width of the two letters of KO is 6cm. When testing with this instrument, the new pattern formed by the two virtual images will become the Englis...

Embodiment 3

[0042] A method of observing the development process of myopia by using the telephoto method and detection equipment, and actively guiding people to look into the distance to prevent myopia. The phenomenon that the virtual image of an object is staggered. Take the person's own arm as a middle point, and take the determined telescopic object as the telescopic point; and hold a detection device, and then guide the human eye to look at the distant telescopic point through the middle point of the arm; at this time, in the human eye A detection device that can form a certain virtual image is installed in the telescopic line of sight, and whether the eyes are nearsighted is judged by observing the imaging characteristics of the virtual image. The detection equipment is a group of fish-shaped patterns (such as figure 1 shown). Among them, the fish on the right is a hollow fish, and the fish on the left is a small fish smaller than the hollow on the right. As long as the center of t...

Abstract

The invention relates to a method for detecting the development process of short sight and a detecting tool for inducing telescoping. The method is a detecting method which utilizes the phenomenon that the virtual image of the same object nearby seen by two eyes is staggered when two eyes see an object nearby with the focus of seeing an object far away; the own arm of a person is taken as an intermediate point and the telescoping object as a telescoping point; eyes are induced by the detecting tool held by one hand and to see the telescoping point far away from the intermediate point of arm; the detecting tool that can form a certain virtual image is arranged in the line of telescoping sight of people; and whether the eyes are short-sighted is determined by observing the imaging characteristics of the virtual image. The detecting tool can be formed by using various beneficial graphs, but the width of the detecting tool is ensured to adapt to the interval between two pupils of eyes; when eyes are normal, the width of the detecting tool is equal to the interval between two pupils of eyes; and when eyes get short-sighted, the width of the detecting tool is reduced proportionally under the condition of taking the interval between the two pupils of eyes as a standard value according to the short-sight degrees of eyes.

Description

technical field [0001] The invention relates to a detection method and a device, in particular to a method for observing the development process of myopia of human eyes by using a telescopic method and a detection device, and actively guiding people to look into the distance to prevent myopia. technical background [0002] According to relevant statistics, there are more than 30 million new myopia patients in my country every year, and the incidence is mainly concentrated in center students. And its development trend is getting younger and younger. This is mainly due to the continuous progress of society and the increasing burden of learning. [0003] At present, it is used to detect whether the eyes are nearsighted, mainly through the international standard eye chart. The distance between the eyes is 5 meters during the test, and it cannot detect the "myopia" in which the far point of vision of the normal eye develops from infinity to myopia to 5 meters. Eye". Often the ...
