Eye vision function assessment device and eye vision function assessment method

Abstract

The invention provides an eye vision function assessment device and an eye vision function assessment method. The device comprises a display module, an operating module and a processing module. The display module comprises two optical lenses and two display screens, and the processing module comprises an image processor and a central processing unit. The central processing unit controls the imageprocessor to generate a selection operating picture for a user to select eye vision function test, the display screens display the picture, and the central processing unit controls the image processorto generate two testing pictures and controls the two display screens to display respectively; in order to matching display magnification times of different pictures and guarantee measurement precision, the two optical lenses perform fixed-ratio zoom processing on the two pictures displayed by the display screens; after the user completes the test, the central processing unit assesses two eyes ofthe user according to testing operation of the user to obtain current assessment information, and the current assessment information is displayed on the display screen while data are stored in a storage space and can also be transmitted to other data platforms through a wireless device (Bluetooth and the like).

Description

technical field [0001] The invention belongs to the field of ophthalmic optics, and in particular relates to an ocular function evaluation device and an ocular function evaluation method. Background technique [0002] In China, the special visual function inspection instrument jointly developed by Changchun Aopu Optoelectronics Technology Co., Ltd. and the Fourth Military Medical University consists of four main parts: optical system, mechanical system, electric control, and computer. It is mainly used for the detection of visual functions such as contrast sensitivity, fast dark adaptation, stereo vision, heterophoria, distance vision, near vision, color vision, etc. It is also suitable for various types of driver's physical examination and hospital examination. Functional requirements of the electronic system: visual mark graphics generation, display, function conversion, man-machine communication, recording, storage, printing, etc. But the volume is 512mm×502mm×590mm, and...

AI Technical Summary

Problems solved by technology

[0016] Judging from the status quo of international visual function testing equipment, some equipment has partial visual function evaluation capabilities, but the operation is complicated, and different pictures need to be replaced; some only have visual inspection, and the functions are not very comprehensive.
