Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing:

[0025] Such as figure 1 , figure 2 As shown, a quick-assembled optical corrective eyeglass assembly is characterized in that it includes a circular lens 1 with a prescription, a frame 2 matching the circular lens 1, and a combined scale plate 3. The lens 1 preferably has a diameter of 25 mm to 59 mm. The mirror ring of the mirror frame 2 is circular, and the distance between the centers of the mirror rings is 52 mm to 74 mm. In order to facilitate comparison of angles, the diameter of the circular lens 1 is greater than the diameter of the horizontal axis scale 32, and the size of the center points of the two circles ranges from 52 to 74, with an increment of 1 mm, and 23 sizes of a certain diameter are produced. series of frames.

[0026] Such as image 3 , Figure 4 As shown, the outer surface of the lens is provided with a circle of sharp edges 13 or inwardly rece...

Abstract

The invention discloses an optical corrective spectacles component without center shifting during quick assembly. The optical corrective spectacles component is characterized by comprising round lenses with matched dioptre, a lens frame matched with the round lenses and a combined scale plate, a circle of sharp edges or inwards-concave line grooves are formed in the outer side face of each lens, and a central mark is formed in the center of each lens; horizontal axial marks are arranged at positions with 0 degree and 180 degrees at the edge of the surface of each lens, and the combined scale plate comprises a rectangular baseplate and a horizontal axial scale gauge integrally connected with the rectangular baseplate. The round lenses small in diameter are adopted, so that raw materials are saved; the lenses can be directly produced and formed in original plants or warehoused for processing, so that time-consuming reprocessing during spectacles prescribing, and trial wearing and quick assembly can be realized in a retail link; the round lenses are free of center shifting, so that optimal optical performance can be realized; coverage is wide.

Description

technical field [0001] The present invention relates to an optical corrective spectacle assembly, in particular to an optical corrective spectacle assembly that can be quickly assembled without shifting the center and its dispensing method Background technique [0002] The existing optician method needs to take a fixed-degree lens (generally with a diameter of 70mm, 72mm, and 75mm) to fix the point with a lens meter, and then process it. This method leads to a long period of optician and a high cost of optician. [0003] In the present invention, the optical glasses are assembled by using circular lenses with sharp edges or opening grooves around the outer ring with a matching degree and a matching frame and a combined scale plate with an integrated design, and are assembled into optical glasses, which can be widely used in The optician industry has a great market prospect. Contents of the invention [0004] The purpose of the present invention is to solve the problems of...
