FIELD: physics.
SUBSTANCE: glasses without arms formed by two optical systems, have own support on the user nose and fixed on it without an bending of the cross connection. All parts of glasses are comprised in a single detail cut in a sheet of pre-fabricated continuous material. The glasses contain two areas with optical properties, cross connection field, inflexible in the same plane of the sheet and two fixing plates, connected with the sections of optical properties connected by a common area. Meanwhile the single cut sheet of the continuous material is configured so that to form flexural fields, where the sheet is flexible in connecting and common fields, exerting necessary pressure on plates for fixing in support points of the user.
EFFECT: simplification of manufacture technology, safety of the use of glasses without arms.
