Problems solved by technology

[0003] In order to overcome the shortcomings of inaccurate hand waving that causes doctors to be unclear about people's vision, and people need to hold a sign to block their eyes. When the sign is taken off, the light will easily cause people's eyes to be uncomfortable. A vision test aid that enables doctors to better understand the direction of letters that people are looking at, and also allows the covered eyes to slowly adapt to the light

Abstract

The invention relates to an auxiliary device, in particular to an auxiliary device for visual examination. The auxiliary device for visual examination can make doctors clearly know the directions in which people see letters, and can make shielded eyes slowly adapt to light. According to the technical scheme, the auxiliary device for visual examination comprises mounting plates, an elastic belt, anarc-shaped sliding rail, arc-shaped sliding blocks, a baffle, pull blocks, hooks, a fixing frame, limiting blocks, protective frames, an arc-shaped plate, a disc, an E-shaped pipe and the like. The elastic belt is connected between the lower parts of the inner side faces of the left and right mounting plates, and the protective frames are installed on the upper parts of the inner side sides of the left and right mounting plates. The protective frames are symmetrically arranged, and openings are formed in the middles of the protective frames. The device is worn on the head, the baffle is usedfor blocking one eye, the other eye is subjected to visual examination, and the auxiliary device is more convenient to use. Through the function of the E-shaped pipe, the doctors can clearly know thedirections in which people see the letters.

Description

technical field [0001] The invention relates to an auxiliary device, in particular to an auxiliary device for visual inspection. Background technique [0002] In order to know how their eyesight is, people will go to the hospital for a vision test, usually by looking at the eye chart to check their eyesight. Generally, when people perform a vision test, they need to wave their fingers and point to the letters corresponding to the letters on the vision chart. The direction, because the inaccurate hand waving makes the doctor unclear about people's vision, and people need to hold the sign to cover the eyes. When the sign is taken off, the sudden light will easily cause people's eyes to feel uncomfortable, so the doctor will ask repeatedly. What direction people are pointing in is so easy to cause people to be very upset. Contents of the invention [0003] In order to overcome the shortcomings of inaccurate hand waving that causes doctors to be unclear about people's vision,...
