Vision detection device

Abstract

The invention provides a vision detection device. The vision detection device comprises an eye covering device and a central control machine. The eye covering device comprises a shell, a control panelinstalled in the shell, a power supply electrically connected with the control panel and a key installed on the shell. The central control machine is used for displaying a vision detection icon, receiving a signal sent by the key, converting the signal into a vision detection result and storing the vision detection result. The control panel of the eye covering device is in communication connection with the central control machine, a detector judges the signal of the vision detection icon through the key and can transmit the signal to the central control machine, and the central control machine can compare the signal with the direction of the vision detection icon so as to obtain the vision detection result and store the vision detection result. Therefore, a traditional voice confirmationmode is replaced with the key, the limitation of the detection environment and the conditions of a detected person is avoided, the use limitation of the vision detection device is small, and the adaptability is good; and moreover, medical staff do not need to accompany in the whole process, autonomous and independent detection can be achieved, and the labor cost is low.

Description

technical field [0001] The present application belongs to the technical field of vision detection, and more specifically relates to a vision detection device. Background technique [0002] During the vision test, usually the medical personnel designate a vision test icon on the display screen, and then judge whether it is correct or not according to the voice of the tester. By repeating the above operations, a preliminary understanding of the visual acuity of the tester can be obtained. However, the method of voice communication between medical staff and testers has the following disadvantages: 1. In a noisy environment, the recognition of voice communication is weak, which affects normal communication and thus affects vision judgment; 2. For special Crowds of people, such as the deaf, cannot communicate by voice, which affects the smooth progress of vision testing; 3. Medical staff are required to accompany them throughout the process, and the labor cost is high, making it...
