Integrated visual function equipment and implementation method

Abstract

The invention provides integrated visual function equipment and an implementation method, which meet the requirements of visual screening, examination and training of large-scale crowds in a limited space and belong to the field of visual function testing, visual examination, refraction examination and visual function examination are integrated into one piece of equipment, far visual examination can be simulated in the limited space, and the visual function testing efficiency is improved. The transportation cost of the screening equipment is reduced, the requirement for labor of screening work is lowered, the time for a user to switch different equipment is saved, and screening is more convenient. Each eyepiece disc is provided with a plurality of layers of eyepiece discs, each eyepiece disc is provided with a plurality of lenses, and the lenses of different specifications can be combined through independent rotation; the device can simulate a long-distance sighting mark in a small space, the actual distance of 5 meters is not needed, the inspection distance is shortened, and the whole device is small in size. Through the compact arrangement of the movable frame, the front-back adjustable baffle, the lens control panel, the system core board, the button, the display screen, the supporting frame and the loudspeaker, the visual function equipment has high integration, and the man-machine interaction experience of a user is greatly improved. The visual function equipment provided by the invention is small in occupied space and high in flexibility, and the visual screening efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the field of visual function testing, and in particular relates to an integrated visual function screening device and a realization method. Background technique [0002] With the increasing incidence of myopia among adolescents and the inclusion of adolescent eye health in national policies, eye health screening in schools has been more popularized and valued. [0003] Before eye screening, only vision was checked for a long time. As people pay more attention to the eye health of young people, some regions with conditions have gradually added refraction screening. At present, the commonly used refraction screening tools on the market include purely objective inspection tools such as automatic computer refractometer and refraction screener. The deviation may be as high as 3.00D or even more, and the accuracy of judgment is greatly affected. Especially for children whose actual diopter is mainly distributed in 0-+3.50D without ...
