ABSTRACT:
The present invention relates to an eyeglass device having two pairs of glasses which are integrated together by placing one pair of glasses over the other pair of glasses. There have been methods by which two pairs of glasses are combined into one pair of glasses. However, these glasses have had several problems such as weak combining strength or removal of one pair of glasses for their storage. The present invention comprises primary glasses and auxiliary glasses, the auxiliary glasses being attached to the primary glasses by insert slots formed in the primary glasses in order to improve the combining strength, and are able to be folded up when not used in order to provide the same effect as being removed, without being removed from the primary glasses.
