Abstract
The present invention relates to eyeglasses having a selectively detachable pattern layer, and relates to a technology wherein one or more pattern layers having variously shaped images are attached on a surface of a main lens or an auxiliary lens to satisfy wearers' needs and provide convenience for wearers, allow wearer to show off his or her own individuality or expression, and induce curiosity and interest of a viewer, and a support is provided to reduce friction between the main lens or the auxiliary lens and the pattern layer.
