摘要:
Reading glasses, more specifically pince-nez glasses, for short-term, close viewing and reading. For better placement of the reading glasses on the nose, the bridge of the reading glasses is provided with knobs, of which two are located on the outside, making it comfortable to grasp and place the glasses on the nose with two fingers and third knob is located on the upper centre of the bridge. Bridge of the reading glasses is ergonomic. The measurements of the radius of bridge of the reading glasses have been developed ellipsoidal in shape, where radius r1 is 7.0 mm and r2 is 7.5 mm and the angle α of the bridge is 36°.
