Abstract

PURPOSE: To eliminate unnatural way of using the bifocal spectacles and prevent fatigue by making nose rests relatively slidable and movable in the vertical directions with respect to the spectacle frame.
CONSTITUTION: The nose rests are constituted by perpendicular bar bodies 5, 5' connecting to the nasal septum contact points 4, horizontal bar bodies 6, 7 connecting between the bar bodies 5, 5', etc. and are relatively slidable in the vertical directions with respect to a spectacle frame 3 by way of the sliding brackets 10 provided with the U-form sliding bearing covers 8 sliding the bar bodies 5, 5'. Hence, when the frame 3 is moved vertically while the spectacles are held put on, the bifocal spectacles may be used without moving the eyeballs, thus the occurrence of fatigue owing to unnatural use may be prevented.
