The spectacle (1) has a frame (2) extending in a transverse direction (28), where the frame is provided with an upper frame portion (4) and a lower frame portion (5). The lower frame portion is connected to the upper frame portion in a central region (6). A removable glass (3) is replaced by the lower frame portion relative to the upper frame portion. The lower frame portion is moved from a retracted end position in a longitudinal direction (29) to an extended end position, where the longitudinal direction is perpendicular to the transverse direction. |
