PURPOSE:To increase corrosion resistance, wear resistance and strength and to avoid spectacles from being slipped down even at increased body temperature, by forming nose pads and legs used for spectacles with nickel-titanium alloy. CONSTITUTION:By forming nose pads and legs for spectacles with the nose in wearing spectacles with a nickel-titanium alloy as this invention, the strength, corrosion resistance and luster are sufficient for spectacles and the shape storing performance is excellent. When the temperature of nose is increased due to sweat in the body, it is prevented spectacles from being slipped down, which can not have been performed good by temples 1 only, by processing the pads and legs so that they are tightened in accordance with the temperature rise of nose, allowing this invention to prevent spectacles from being slipped down in a good manner. |
