Embodiment Construction

[0054] The specific embodiments of the present invention will be further detailed below with reference to the accompanying drawings:

[0055] In the present embodiment, the apparatus and method of automatically measuring the visual optical parameters of human eye, corneal curvature, pupil diameter, etc. in a non-contact manner. In the following description, the device is set to the Z axis with respect to the direction of the patient's eye 12, and the direction of the z-axis is vertical and the direction parallel to the ground is set to the x-axis, and the Z axis is vertical and vertical with the ground. The direction is set to the Y axis.

[0056] The apparatus of the present embodiment is mainly composed of an optical path assembly and a three-dimensional motion platform. Among them, the optical path components are composed of a refractive measurement system, a curvature measurement system, and an autofocus system. like figure 1 As shown, the refractive measurement system include...

Abstract

The invention relates to a full-automatic human eye visible light inspection device which is composed of a light path assembly and a three-dimensional motion platform. The light path assembly is fixed to the upper end of the three-dimensional motion platform; alignment with human eyes is completed through movement of the three-dimensional motion platform in the X direction, the Y direction and the Z direction; the light path assembly is composed of a refraction measuring system, a curvature measuring system and an automatic focusing system; the refraction measuring system is used for measuring the diopter of human eyes; the curvature measuring system is used for measuring the curvature of the human cornea; and the automatic focusing system is used for positioning human eyes. The invention further relates to a full-automatic human eye visible light inspection method. The device and the method can automatically measure visual optical parameters such as the diopter of the human eyes, the corneal curvature, a pupil diameter and the like in a non-contact manner, are convenient to operate and high in efficiency, and have relatively high innovativeness.

Description

Technical field [0001] The present invention belongs to the technical field of Optometry, relates to a device for measuring near-infrared light source as a light source, a comprehensive inspection camera through the optical lens and the human Optometry function, in particular a human automatic inspection apparatus Optometry and methods. Background technique [0002] Myopic refractive error was listed as one of the world's three major eye diseases that my country is a big country myopia, myopia number of nearly 400 million, of which about 270 million young people. 2018, the incidence of myopia students ranked second in the world, the number of myopia in the world. Therefore, the Ministry of Education and the National Board of Health intends to health prevention and control of myopia in children and adolescents, the overall incidence of myopia and physical health status into the government performance assessment indicators. In order to better carry out prevention and control of myo...
