The invention relates to foldable spectacles comprising two lenses (1a, 1b) which can be adjusted between a support position and a folded position and which are connected to each other by means of a nose piece (10). The nose piece (10) extends on a connecting axis (I) which is arranged on a plane of the spectacle lens and comprises a folding joint (15) which is used to fold the spectacles. The folding joint (15) can be rotated about a rotatable axis (m) which extends at an acute angle (β) to the connecting axis (1), such that the spectacle lenses (1a, 1b) are arranged on the same plane next to each other in a folded position after a 180° rotation.
