Glasses and method for detecting myopic number of degrees

Abstract

The invention relates to glasses and a method for detecting myopic number of degrees, belonging to the technical field of vision detection. A first mirror body and a second mirror body in the glassesare connected to form an accommodating cavity in a front-back sliding manner, an elastic transparent airbag is arranged in the accommodating cavity, two sides of the elastic transparent airbag are respectively fit with the first mirror body and the second mirror body, and a liquid injection transmission mechanism for injecting focusing liquid into the elastic transparent airbag and adjusting the volume of the accommodating cavity is arranged in a mirror bracket. The glasses have the beneficial effects that the first mirror body, the second mirror body and the elastic transparent airbag filledwith the focusing liquid are taken as an equivalent concave lens, the distance between the first mirror body and the second mirror body is adjusted through changing the volume of the focusing liquid in the elastic transparent airbag, and the required number of degrees of the glasses is determined according to the position of the liquid injection transmission mechanism, so that the detection of thenumber of the degrees is accurate and continuous, the operation process is convenient and rapid, the detection cost is low, the detection of the number of the degrees can be finished by one people, the glasses can meet the current configuration demands of myopic glasses, and the configuration cost is lowered.

Description

technical field [0001] The invention relates to the technical field of visual acuity detection, in particular to glasses for detecting the degree of myopia and a method for detecting the degree of myopia. Background technique [0002] Nowadays, there are more and more people with myopia. In order to meet the needs of daily life, they are equipped with glasses of different degrees. Moreover, due to the excessive use of eyes in people's daily life, the degree of myopia will still increase, and it is necessary to re-examine the glasses many times. . At present, the general configuration method of glasses is based on constantly changing lenses, and then go to the eye chart to get the most suitable lenses, and then prepare suitable glasses according to the degrees. The process of dispensing glasses will waste a lot of time; The method needs to make the inspection lens in advance, which is not only inconvenient to operate, time-consuming and laborious, but also consumes materials...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the above technical problems, the present invention provides a kind of glasses for detecting the degree of myopia, which mainly solves the problems of low efficiency and high cost of the existing method for detecting the degree of myopia. Glasses with low cost and one inspector can complete the degree detection to meet the current configuration requirements of myopia glasses and reduce configuration costs
