Abstract

The invention discloses vision screening equipment which comprises a device shell with a cavity, a diopter measuring device, an external display, an internal display, a main control unit and a control unit, the control unit, the diopter measuring device and the built-in display are respectively in communication connection with the main control unit; the built-in display is provided with an electronic visual chart display module, and the external display is provided with a result display module; wherein the device shell is provided with a window, and a visual reflecting mirror for a user to observe is installed at the position, corresponding to the window, in the cavity; and a light path of the diopter measuring device and a light path of the built-in display respectively pass through the visual reflector and the window. According to the vision screening equipment disclosed by the invention, the structure of a product is optimized, the integration level of the product is high, a user can finish diopter measurement and naked eye vision measurement by standing in front of the window, repeated movement is not needed, and the vision screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vision inspection, in particular to a vision screening device. Background technique [0002] Vision assessment needs to measure the diopter parameters of the user's eyes first, and then observe the eye chart to determine the naked eye vision. [0003] In the prior art, vision screening equipment is usually used for vision screening. During the screening process, the user needs to move at least twice to complete a vision screening. For the first time, the user moves to a certain distance in front of the vision screening device to measure the diopter to obtain the diopter parameters. After that, the user needs to move for the second time to observe the eye chart to measure the uncorrected visual acuity. [0004] The existing vision screening equipment has a slow vision screening process and takes a long time, and its structure and integration performance still need to be optimized. [0005] In view of th...
