Abstract

A computer optometry unit comprises a workbench, a master control computer, a base and a support connected to the workbench and the base. The computer optometry unit further comprises a visible light video camera, an infrared optometry unit and a transmission device provided with a motor. The visible light video camera is movably arranged on the support, and the visible light video camera, the infrared optometry unit and the motor are connected with the master control computer. The optical axis of a lens of the infrared optometry unit and the optical axis of a lens of the visible light video camera are located on the same vertical plane. The computer optometry unit further comprises a pressure switch arranged in the center of the upper surface of the workbench and connected with the master control computer. The computer optometry unit is high in automation degree, optometry repeatability and effectiveness, capable of greatly saving optometry labor cost and optometry time, and high in precision.

Description

technical field [0001] The invention relates to an ophthalmic medical detection device, in particular to a computer optometry instrument. Background technique [0002] At present, there are many optometry equipment on the market, such as comprehensive optometry instrument, automatic optometry instrument, etc. In the optometry process, optometry instrument is an objective optometry instrument, which emits a beam of infrared light of a specific wavelength through the cornea, The lens, aqueous humor, retina and other eyeball organs are finally projected to the eyeball retina, and then reflected back to the corresponding optical system of the instrument, and then received by the CCD, which converts the optical signal into an electrical signal, and decomposes the spherical lens, cylindrical lens and axial position, etc. The data can be used to obtain parameters such as the diopter of the eye to be inspected. Existing computer optometry requires a professional optometrist to perf...
