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.

Embodiment Construction

[0067] The main purpose of the present invention is to provide a method for assembling an add-on lens that can select the type of lens to be used according to the function required by the consumer, and can match the shape of the frame of the glasses used.

[0068] Such as figure 1Shown is a structure of an external lens 10 assembled by the method of the present invention and a pair of glasses 20 used in conjunction with the external lens 10 . In this embodiment, the glasses 20 are thin frame glasses, which have two lens frames 21 , two main lenses 23 disposed in the lens frames 21 , and a bridge 22 connected between the two lens frames 21 . The external lens 10 includes two additional lenses 12 and a suspension component 11 connected between the two additional lenses 12 .

[0069] The feature of this external lens 10 is that the suspension component 11 it adopts is made of metal material, and the same material and color as the frame material of the glasses 20 can be selected,...
