Novel improved vision detection device

Abstract

The invention belongs to the technical field of vision detection, and particularly discloses a novel improved vision detection device, which comprises a device whole, a display screen and a disinfection drawer, an auxiliary device is fixedly connected to the middle of the top end of the device whole, the display screen is fixedly connected to the top of the device whole, and a host is tightly attached to the rear end of the bottom of the display screen. A disinfection drawer is connected to the right side of the middle of the whole device in an embedded mode, the bottom end of the disinfection drawer is movably connected with a roller set, and the roller set enables a user to open or close the disinfection drawer more easily; through the arrangement of the sterilization mechanism, when a user uses a public tool to perform vision detection on a detected person, the sterilized and disinfected public tool can be intermittently used by other detected persons in a replacement mode; and therefore, the health of a detector cannot be affected by the fact that the detector and a detector carrying germs use the same public tool, and the device embodies safety.

Description

technical field [0001] The invention belongs to the technical field of vision detection, in particular to a novel and improved vision detection device. Background technique [0002] The quality of vision is judged by the ability of the retina to distinguish images. However, when the refractive medium of the eye becomes cloudy or has refractive errors, the vision of the eye with good retinal function will still decline. Regularly test the vision and know your own vision in time. Vision condition, which is convenient for timely adjustment or treatment, which is beneficial to delay vision deterioration or improve vision. [0003] At present, the existing vision testing devices display the test table through electronic equipment, but the existing vision testing devices cannot automatically cover the surface of the electronic equipment after the user finishes using it, so that the outside dust is easy to contaminate On the surface of electronic equipment, it will affect the use ...

Problems solved by technology

[0005] The purpose of the present invention is: in order to solve (cannot block the electronic display device after use, can not display the test distance of the side view during use and will cause the use of light-shielding glasses because there is no disinfection treatment for the light-shielding glasses People have the problem of cross-infection), providing a new and improved vision detection device
