Measuring device for providing comfortable experience for measurer

Abstract

The invention discloses a measuring device for providing comfortable experience for a measurer, which comprises an eye optometry unit; an examination window is arranged on the eye optometry unit, the lower part of the examination window is provided with a vertical fixing rod; a head placing plate is arranged on the fixing rod, and a jaw placing slot is arranged on the surface of the head placing plate; a holding plate is arranged at the lower part of the head placing plate, and the lower part of the holding plate is provided with two arc supporting plates; the arc supporting plates are connected with the fixing rod through a connecting rod, and the bottom part of the fixing rod is provided with a fixing base; one side of the holding plate far from the fixing rod is connected with a vertical overturning plate, and one side of the overturning plate is hinged with the holding plate; a sitting plate is connected to the inner wall of the overturning plate. The fixing device can provide a head supporting device for a user and prevent the head part of a patient from swaying during the measuring process, or prevent the head part from being too tired for keeping a gesture for a long time, thus the patient has a more comfortable detecting environment, and the measuring device can facilitate the use of people at all ages.

Description

technical field [0001] The invention relates to a fixing device, in particular to a measuring instrument providing a comfortable experience for a measurer. Background technique [0002] With the advancement of living standards and science and technology, more and more teenagers suffer from myopia, which is also called short-sightedness, because this kind of eye can only see near but not far. When in a resting state, the parallel light from infinity is refracted by the eye's refractive system and then converges into a focal point in front of the retina, forming an unclear image on the retina. Electric optometry is developed by combining modern optics and computer technology. It is an automatic instrument used to objectively detect the refractive state of glasses. It is mainly used to detect the degree of myopia of human eyes. Computer optometry belongs to objective optometry. Its principle is the same as The retinoscopy method is basically the same, using infrared light sour...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the accuracy of the computerized refractor is affected by many factors, such as the patient's head and eyes are not well coordinated, they move around, and the eyes are not concentrated enough to focus on the target in the refractor, so that the relaxation and adjustment are not enough. Affects the accuracy of the diopter test results. At the same time, adults and children have different heights, so it is not convenient to measure the eye power of various groups of people. The purpose is to provide a measuring instrument that provides a comfortable experience for the measurer and can provide the user with a head placement support device. , to prevent the patient from shaking the head during the measurement process, or keeping the head in one position for a long time is too tiring, so that the patient can have a more comfortable testing environment, and it is convenient for people of all ages to use
