Eyeglass change structure

The present invention relates to a lens changing structure, in particular to a lens in which the lens and the frame are combined at a central position to keep the curvature of the lens constant, so as to provide a lens changing structure for the multi-frame assembly.

In order to prevent ultraviolet rays from harming the eyes during outdoor activities, people are used to wear sunglasses when they go out to protect their eyes from being damaged by ultraviolet rays. The sunglasses not only have the effect of protecting the eyes, but also are regarded as a match. Apparel styling accessories, therefore, in order to meet the needs of different consumer styling, existing sunglasses in addition to focusing on anti-UV function, but also pay attention to its design, and existing sunglasses can also be active assembly of its frames and lenses, in order to facilitate the shape change.

However, with the popularity of 3C products such as TVs, computers, and mobile phones, the ratio of myopia has increased year by year. The more people need to wear optical glasses to correct their vision, the more demand for sunglasses is increased, and the number of lenses is mainly used by them. Curvature produces corrective visual effects. When the curvature changes, it will produce out-of-focus, distortion of viewing scenes, etc., and the existing sunglasses assembly structure design, after bending the lens, the flanges on the two sides of the lens are respectively The two sides of the frame are positioned in the side groove, so that the angle of the design of the two sides of the same frame is not the same, let alone different frame frames, and the angle of the groove is different, which will cause the lens. After the embedding, the curvature of the arc is different, which causes the curvature of the lens to change. Therefore, the existing solar cell assembly structure is difficult to apply to the degree of the solar lens. Therefore, the existing sunglasses lens can only be assembled with a mirror frame.
