Digital visual function detecting instrument

Abstract

The digital visual function detecting instrument includes a crystal liquid display system, an automatic height regulating device for the display system, a computerized control system, a pedestal, and a remote controlled emitter / receiver device. The computerized control system accepts and executes the command from the remote controlled emitter / receiver device to call corresponding visual detection program. The digital visual function detecting instrument has also an optical display system for detecting polarization, stereo or fused vision, and an automatic rotation system for switching between the crystal liquid display system and the optical display system. The present invention has increased visual detections with the optical display system, automatic switched power source access, automatic display screen height regulation and other functions, and possesses perfect functions and simple operation.

Description

technical field [0001] The invention relates to a medical testing instrument, in particular to a digital visual function testing instrument. Background technique [0002] The applicant has disclosed in the invention patent application 200510050128.X and the utility model patent application 200520103059.X a device that can automatically adjust the height of the display screen, and the detection program can be set by the computer, which can perform shape, color, and kinesthetic sensations on the tested person. It is a computer vision tester that can test the visual acuity and contrast visual acuity separately, and at the same time make an objective judgment on the visual acuity of the person being tested. , the computer receives the instructions sent by the remote control transmitter, the software executes the operation instructions, and the operation software is equipped with programs and graphics corresponding to various content of vision detection; the seat height signal tr...

Problems solved by technology

In this technical solution, the height of the display screen can be automatically adjusted, and the detection program is set by the computer, which can detect the shape, color, kinesthetic and contrast vision of the tested person separately, and at the same time make an objective judgment on the visual status of the tested person. However, this solution lacks the detection functions of polarization vision, stereo vision and fusion vision, and at the same time cannot realize automatic conversion according to the power supply voltage level, and the function is not yet perfect.
