Embodiment

[0043] Such as figure 1 and figure 2 As shown, a method for manufacturing spectacle lenses that reduces chamfered imaging interference, the specific method is to reduce the light emitted by the light spot from entering the eye from the chamfer by changing the structure of the edge chamfer 13 on the side of the spectacle lens 1 away from the eye pupil 21 The intensity of the pupil 21.

[0044] The production of glasses requires many delicate processes. Due to cutting, the edges of the lenses become sharp and sharp, which poses a safety hazard, so the chamfering of the concave and convex surfaces is an essential operation. Such as Figure 3-1 to Figure 3-3 As shown, taking the lens of myopia glasses as an example, because of the existence of chamfer 13 on the convex edge of the lens, there are two paths for the light emitted from the surface of the front object to enter the eye 2, so the eye 2 will see two kinds of images: ① light emission → Convex surface 11→mirror body→con...

Abstract

The invention discloses a method of manufacturing a spectacle lens for reducing the chamfer imaging interference. To be specific, according to the method, the edge chamfering structure of one side, away from an eye pupil, of a spectacle lens is changed to prevent the intensity of light passing a chamfer angle or reduce the intensity of light that is emitted by a light spot and enters the eye pupil through the chamber angle, thereby reducing the interference of a similar kaleidoscope effect and improving the wearing quality of the spectacle. Since the reflection interference from the lens is applied in a spectacle wearing process, the interference degree of the similar kaleidoscope effect is reduced to be below the own reflection interference of the lens based on the disclosed method to realize a level that can be received by the human eyes.

Description

technical field [0001] The invention relates to the technical field of spectacles, in particular to a method for manufacturing spectacle lenses that reduces chamfering imaging interference. Background technique [0002] In modern times, with the changes in people's lifestyles, such as long-term indoor work; frequent use of electronic devices such as computers and mobile phones; and reduced outdoor activity time, the prevalence of myopia is increasing rapidly around the world, and glasses have become a popular choice for many people. A partner that people rely on to see things. [0003] There are many factors that affect the visual effect and comfort of wearing glasses, such as the optical quality of the lens, the error between the glasses and the actual situation of the eyes, the prism effect, etc. In addition to these known factors, there is actually an "invisible killer" , always stimulate the optic nerve, interfere with the line of sight, and increase eye fatigue, but it...
