Vision detection device

Abstract

The invention provides a vision detection device, and relates to detection equipment and facilities. Th vision detection device comprises a lamp box, a plane mirror is arranged in the lamp box, a plurality of light supplement lamps are further arranged in the lamp box, a vision plate is arranged on the front surface of the lamp box, a connecting plate is connected to the rear surface of the lamp box, the connecting plate is connected with one end of a supporting device, and the other end of the supporting device is connected with a base. By adjusting the angles of the light supplementing lamp and the plane mirror, the brightness of the interior of the lamp box is realized, so that a lamp tube is prevented from directly irradiating the eyes and hurting the eyes, meanwhile, the brightness and the detection accuracy in the lamp box can be ensured through the refraction of the mirror and the refraction of the light supplementing lamp; through cooperation of the supporting device, the connecting device and the connecting plate, the height of the vision plate can be adjusted, meanwhile, the eyesight plate can be rotated, the vision plate can be suitable for people of all heights to use in a bidirectional adjusting mode, the whole device is enabled to be universal, and convenience is brought to the user.

Description

technical field [0001] The invention relates to a detection device and facility, in particular to a vision detection device. Background technique [0002] The eyeball is one of the most fragile organs of the human body, especially in the current era of information explosion and Internet + era, the human eye is facing a great impact. [0003] There are many kinds of eye diseases and complex, and once suffering from eye diseases, it is difficult to cure, but before the outbreak of eye diseases, there will be warning signs. Therefore, the timely detection and dynamic observation of eye vision are of great significance to the prevention and control of eye diseases. [0004] At present, the main method of visual acuity testing is still the traditional eye chart. The eye charts used in China include international standard eye chart, logarithmic eye chart, Langer’s surround vision eye chart, and some LED light box eye charts. [0005] But existing visual acuity detection device h...

AI Technical Summary

Problems solved by technology

[0005] But existing visual acuity detection device has following shortcoming: 1, the brightness of light box has no way to regulate, even if adjustment also is to adjust the power of lamp tube, when light box is dark, the tester can't test real eyesight, when light box is bright, to The eyes of the tester will be hurt, which will bring a lot of inconvenience to the user; 2. The position of the light box of the existing detection device cannot be moved, and it is the position where it is installed, but some people are tall and tall during the detection process. Different, resulting in different observation positions will affect the accuracy of detection and bring a lot of inconvenience to users
