PROBLEM TO BE SOLVED: To provide spectacles which has means for automatically regulating the angles of lenses in looking up and viewing near and viewing far, prevents the occurrence of a deviation in the central points of the lenses and errors in the angles with respect to the line of sight in looking up and viewing near by regulating the angles of the lenses by a simple operation and makes it possible to obtain a feel of comfortable use by eliminating the fatigue and discomfort of the eyes caused by the deviation of the line of view from the centers of the lenses by the conversion of both eyes and mainly by the errors of the angles. SOLUTION: The spectacles having a spectacle frame integrally formed with temple junctures at both side ends, sliding pins and a lens frame are constituted by forming sliding grooves to the temple junctures, fitting the lenses of the spectacles into the lens frame, integrally formed connection projecting parts in the positions corresponding to the temple junctures of the spectacle frame at one-side end, freely rotationally movably supporting the other ends in the transition sections of the spectacle frame, fixing one-side ends of the sliding pins to the connection projecting parts of the lens frame and inserting the other ends into the sliding grooves formed at the juncture so that the sliding pins slide freely in the sliding grooves.
