ABSTRACT:
A pair of eyeglasses includes a frame unit and a lens unit. The frame unit has a downwardly flaring projection protruding integrally and downwardly from a middle portion thereof, and two constricted slots which are located on two sides of the projection and which have inner end portions that are adjacent to the projection. The lens unit has two upwardly flaring upper portions which define a constricted hole therebetween and which are snap fitted respectively within the constricted slots of the frame unit so that the projection of the frame unit is snap fitted within the constricted hole of the lens unit, thereby retaining the lens unit on the frame unit. The engagement of the projection of the middle portion of the frame unit within the constricted hole in the lens unit facilitates firm connection of the lens unit and the frame unit.
