PROBLEM TO BE SOLVED: To provide spring-up type spectacles which enable a user to surely superpose and arranging additive lenses for, for example, light control and polarization on the front of normal lenses, such as sight correction lenses, with good appearance without shaking and to enable the user to surely spring up the additive lenses to the front of the spectacles without worry about mispositioning and dislodging and to retreat and remove theses lenses from the front of the normal lenses when the light control function is not needed. SOLUTION: While hooking parts 13 and 13 are formed in the upper chordal parts of eyewires 12 and 12 to support the normal lenses 11 and 11 of a front frame 1 of the main spectacles, a browbar sleeve 4 slid and inserted with a pivotal supporting rod 3 is constructed in the upper chordal parts of swing and tilt eyewires 22 and 22 of a front hanging frame 2. Technical means of removably latching the latching ends 31 and 31 of the pivotal supporting rod 3 projecting to both ends of the browbar sleeve 4 to the hooking parts 13 and 13 of the front frame 1 are adopted.
