A functional lens which effectively prevents the separation of a functional layer in a fitting operation of a multilayer functional lens to a frame, and a pair of functional glasses with the lens are provided. The functional lens comprises a lens body and a laminate on the lens body. The laminate comprises, in sequence, a first thermoplastic resin layer, a first adhesive layer, an optically functional layer (e.g., a polarizing film), a second adhesive layer, and a second thermoplastic resin layer. The functional lens is to be fitted in a groove of a frame. The functional lens has an edge face having a shape with a peak. The peak of the edge face is positioned at a fitting side (the lens body side) relative to the first adhesive layer.
