Abstract

The invention relates to a vision testing device, and in particular relates to a protection type vision testing device for the ophtalmology department. The invention aims at providing the protection type vision testing device for the ophtalmology department, which can protect a visual chart and can maintain the cleanliness of the visual chart. In order to solve the technical problems, the following technical scheme is adopted: the protection type vision testing device for the ophtalmology department comprises a mounting frame, a mounting plate, first bearing blocks, first rotation rods, rolling barrels, shielding cloth, the visual chart, belt pulleys, a flat belt, a glass plate, a worm wheel, a second bearing block and the like, wherein the mounting plate is arranged on the top of the mounting frame, the first bearing blocks are arranged on the left and right sides of the mounting plate, the first rotation rods are mounted in the first bearing blocks on the left and right sides, and the rolling barrels are connected to the middle parts of the first rotation rods. With the protection type vision testing device for the ophtalmology department, the effects that the visual chart is protected and the cleanliness of the visual chart is maintained are achieved, through the rolling barrels, the visual chart can be folded and unfolded freely, and thus the effect of protecting the visualchart is achieved.

Description

technical field [0001] The invention relates to a vision measuring device, in particular to a protective vision measuring device for ophthalmology. Background technique [0002] The eye charts used for visual acuity test are all fixed on the wall at present. Since the eye chart is fixed on the wall for a long time, the eye chart is easy to be damaged, and the surface of the eye chart is easy to be dirty due to impurities such as gray layer, and the test result is likely to be caused during the vision test. not allowed. [0003] Therefore urgently need to research and develop a kind of can protect eye chart, can keep the ophthalmic protection type vision measuring device of eye chart cleanliness, to overcome the shortcoming that current eye chart is easy to damage, the surface is easy to dirty and affects the accuracy of test results. Contents of the invention [0004] (1) Technical problems to be solved [0005] In order to overcome the shortcomings of current eye charts...
