Abstract
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°.
Claims8
Reading glasses which have been made of plastic and include two lenses, a lens bridge connecting these and two nose pads on the lens bridge, wherein
- the radius of the lens bridge is ellipsoidal, wherein the radiuses r1 and r2 of the ellipse are from 6.00 to 9.00 mm, more particularly r1 is 7.00 mm and r2 is 7.50 mm;
- the inclination of the sides of the lens bridge of the reading glasses is between 32-40°, more particularly 36°;
- three studs are located on the outer surface of the lens bridge for placing the reading glasses on or taking them off with two or three fingers;
