Embodiment Construction

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] see figure 1 and figure 2 Now, the structure of the vision testing mirror set provided by the present invention will be described. The lens group structure for vision testing includes: a bracket 1 , a connection sleeve 2 , a first lens 4 , an adjustment sleeve 3 and a second lens 5 . The connecting sleeve 2 has a hollow structure and is detachably connected to the bracket 1 . The first lens 4 is mounted on the inner side of one end of the connecting sleeve 2, and the first lens 4 is a transparent product. The adjusting sleeve 3 is screwed to the other e...

Abstract

The invention provides a lens group structure for vision detection, and belongs to the technical field of computer algorithms. The lens group structure for vision detection comprises a support, a connecting sleeve, a first lens, an adjusting sleeve and a second lens. The first lens is mounted on the inner side of one end of the connecting sleeve. The adjusting sleeve is in threaded connection withthe other end of the connecting sleeve, and a first limiting piece is arranged on the inner wall of the adjusting sleeve. One side of the second lens abuts against the other end of the connecting sleeve, and the other side of the second lens abuts against the first limiting piece. The first limiting piece is used for being matched with the connecting sleeve to adjust the curvature of the second lens. The outer edge of the second lens and the inner wall of the connecting sleeve are spaced from each other by a certain distance. The first lens, the connecting sleeve and the second lens form a light-transmitting area. The first lens and the second lens form a lens assembly. The lens assembly adjusts the diopter by means of the first limiting piece. The invention further provides a vision detection method. According to the lens group structure for vision detection and the vision detection method, the vision detection efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of computer algorithms, and more specifically relates to a vision detection lens group structure and a vision detection method using the vision detection lens group structure. Background technique [0002] Glasses are lens lenses embedded in the frame and worn in front of the glasses to improve vision and protect the glasses. In the process of dispensing glasses, it is usually necessary to have an optometry first, and then try them on. Optometry mainly detects left and right eye degrees, astigmatism and interpupillary distance. Astigmatism and interpupillary distance can be measured directly with simple tools. And the determination of existing left and right eye degrees is mostly determined by optometry. Since optometry can only roughly know the power of the left and right eyes, after optometry, it is necessary to wear multiple glasses with different powers to finally determine the most suitable lens. Thi...
