Assembly method for external hanging lenses

Abstract

The invention provides an assembly method for external hanging lens. The assembly method comprises the following steps: frame data acquisition, lens outline design, confirming of a hanging component assembly position, processing of additional lenses and assembly of the external hanging lenses, wherein frame data contain the frame outlines of two lens frames and the relative positions of the two frame outlines; during the lens outline design, the lends outlines of the two additional lens of the external handing lenses are designed according to the frame data, and two lens blanks are processed into the two additional lenses according to the lens outlines; after the additional lenses are processed, a hanging component is assembled with the two additional lenses, so as to complete assembly of the external hanging lenses. Through adoption of the method, the external hanging lenses which can be customized according to the demand of a consumer and fit the appearance of glasses used by the consumer in a matched manner can be manufactured.

Description

technical field [0001] The invention relates to a method for assembling an external lens, in particular to an assembly method for an external lens that can be used with various types of glasses and can be customized according to the needs of consumers. Background technique [0002] Ordinary spectacles are usually equipped with a single function of the lenses. For example, the lenses on vision correction glasses (such as: myopia, hyperopia, astigmatism and other types of glasses) only have the function of correcting vision. When the glasses are required to have additional functions ( Such as: sunshade, anti-blue light, etc.), you must prepare another pair of glasses. [0003] However, it is inconvenient to carry many pairs of spectacles, and purchasing spare spectacles frames will also cause additional financial burden on the user, so there are external eyeglasses on the market. The plug-in lens can mount another pair of additional lenses with different functions (such as su...

AI Technical Summary

Problems solved by technology

[0004] Using the plug-in lens, although the user does not need to buy an extra pair of spectacle frames, and can avoid the inconvenience caused by carrying multiple pairs of glasses, the external shape of the existing plug-in lens is usually not the same as that of the user's original glasses. Do not match, so when the external lens is mounted on the user's original glasses, the shape of the two cannot match, resulting in damage to the aesthetics of the glasses

[0005] In addition, because of the large volume of the suspension components of the existing external lenses, the existing external lenses are heavy and awkward in appearance. When the user wears the external lenses on the glasses, the glasses will be damaged. Increased weight and awkward appearance

[0006] Due to the above reasons, the existing plug-in lenses have the disadvantages of bulky size, heavy weight, and poor appearance. The inventor artificially improves the shortcomings of the existing plug-in lenses. The plug-in lens used in glasses, the structure and appearance shape of this kind of plug-in lens can be matched with the spectacle frame used in conjunction with each other, so as to increase the appearance of the plug-in lens and the original glasses, so as to enhance the aesthetics of use
