Abstract

The invention relates to a tester and in particular relates to a color blindness tester. Aiming at solving the technical problems, the invention provides the color blindness tester which has a simpletesting manner and can improve the testing difficulty. According to the implementation plan, the color blindness tester comprises a support, bearings, screw rods, shaking handles, nuts, first connection rods, second connection rods, wheels, a hollow round plate box, a chuck, a color base plate, a first rotary table and the like; first grooves are formed in left and right sides of the bottom of thesupport; the two bearings are arranged and are embedded at the left and right sides of the support; the screw rods are mounted in the bearings; the shaking handles are fixedly connected onto the screw rods; the screw rods are in thread connection with the nuts. According to the color blindness tester provided by the invention, the color base plate and a color plate are matched so that the testingdifficulty can be improved; after the color base plate is replaced, a test is carried out again, so that the testing difficulty can be further improved; figures on the color plate are observed visually and are compared with figures answered by a tester, so that a color blindness test can be carried out on the tester.

Description

technical field [0001] The invention relates to a tester, in particular to a color blindness tester. Background technique [0002] In order to test color blindness, cards of different colors are needed for this purpose. At present, when testers are tested for color blindness, cards of different colors are usually placed in front of the tester, and then the tester is allowed to pick up the cards of different colors in turn. Cards and tell their colors, but this method is more complicated, so it is difficult to test the color blindness of the testers. In order to improve the difficulty of the color blindness test, the artificial will test the color blindness of cards with numbers in different colors, but color blindness is only for one of them. One color or multiple colors are too heavy, so it is difficult to improve the efficiency of color blindness testing with such a single color card. Contents of the invention [0003] In order to overcome the shortcoming that testers p...
