Abstract

PURPOSE: To prevent lenses from being deformed and slipping from the frames by using a hot worked or heat treated super elastic alloy having a specified low Young's modulus as a material for the rims, etc.
CONSTITUTION: To hold lenses the upper half parts of them are engaged with rims, and the lower half parts are suspended from the rims with thin wires. At this time, the rims are made of known material such as German silver, and the thin wires of super elastic alloy of an Ni-Ti intermetallic compound having a low Young's modulus such as E≤10,000kg/mm2. Thus, frames especially fit for plastic lenses having a high thermal expansion coefft. can be obtd.
