Abstract

PURPOSE: To protect the characteristics of lenses by obtaining the property of following up the thermal expansion of a lens, by using a metal material, which has the shape memory effect and deforms elastically at a prescribed rate, for a rim or thin wire.
CONSTITUTION: For a rim or thin wire that flixes spectacles lenses in a frame, an alloy which consists essentially on an Ni-Ti metal compound of composition with the shape memory effect at the room temperature and deforms elastically by ≥1% on the basis of stress induction maltensite is used. This alloy consists essentially of 49.5W51at% Ni and Ti.
