AI Technical Summary

Technical Problem

Existing vision screening equipment needs to be fixed in a large location and cannot be moved flexibly, resulting in low efficiency and overcrowding for vision checks of primary and secondary school students.

Method used

An ophthalmic device integrating vision testing and refractive error detection functions was designed. It is equipped with a movable base and a main unit drive mechanism. The main unit can be raised and lowered relative to the chassis, and the top cover of the main unit can be raised and lowered relative to the main unit housing, realizing two-level lifting adjustment to meet the examination needs of users of different heights.

Benefits of technology

It enables flexible equipment movement and efficient vision testing, avoids queuing and crowding, improves testing efficiency, and is suitable for vision testing in all classes within schools.

Abstract

This invention discloses an ophthalmic device, including a movable chassis, a main unit integrating vision testing and refractive error detection functions, and a main unit drive mechanism. The main unit includes a main unit housing, a main unit cover, and a cover drive mechanism. The ophthalmic device has vision testing and refractive error detection functions and is equipped with a movable base. The entire device can be moved to designated locations as needed, facilitating use, especially in schools where it can be moved sequentially to each classroom for vision checks, avoiding queuing and congestion, and improving examination and testing efficiency. The main unit can be raised and lowered relative to the movable chassis, and the main unit cover can be raised and lowered relative to the main unit housing. The viewing window is located on one side of the main unit cover, thus enabling two-stage height adjustment to meet the examination and testing needs of users of different heights. Therefore, no external lifting drive mechanism is needed to move the entire ophthalmic device up and down, freeing up the device for transfer between different locations for examination and testing.
