ABSTRACT:
This is a type of eyeglass structure that is an assembly of a main frame and a secondary frame. This utilizes the relationship of the aligned recessed notches of the main frame and the hook sections of the secondary frame. This piece has a main frame and secondary frame, which has the function of assembling and disassembling. This same pair of eyeglasses may house different prescription lenses, sunglass lenses or lenses with other functions. Finally, the secondary frame is formed of a single cast and requires no added processing and is a great advancement!
