PROBLEM TO BE SOLVED: To provide lens-protective spectacles which have a simple structure and is convenient to carry. SOLUTION: Lens frames (10, 10a) holding at least one or more lenses (L) and supporting frames (20, 20a) which extend almost in parallel to lens frame long axes and can have temples (30, 30a) installed at left and right end portions are coupled to each other on lens frame upper sides, and the supporting frames are made rotatable within a range of about 180°on an axis nearly parallel to the lens frame long axes from the lens front to the lens rear, or the lens frames (10, 10a) are made rotatable from the rear to the upper to protect lens surfaces by the temples and also make it easy to carry/store the spectacles.
