SPECTACLES, WORKING PROTECTIVE GLASSES IN PARTICULAR Russian patent published in 2007 - IPC G02C5/14 

FIELD: medical engineering.

SUBSTANCE: device has upper part of ear arc handle shaped as rib manufactured from rather hard polymer material in the zone of contact with ear. Zone from rather soft polymer material with continuous bottom edge is available under the hard rib portion. At least one porous protrusion is available between the bottom edge shaped as rib and the upper rib in soft polymer material. The protrusion is turned towards user head. Several porous protrusions is available. The protrusions are separated with almost vertical ribs from soft polymer material passing between the rib from a firm polymer material and the bottom edge shaped as rib. The end of the handle optionally has loop-like widening through which passes protruding porous soft polymer material. The handle of glasses is optionally produced in cast form with single injection of hard and soft polymer materials.

EFFECT: improved comfort conditions in carrying glasses.
