Abstract

The eyeglasses (2, 2') inserted in the mask part (1) are of approximately hemispherical shape. As a result, optimum matching to the shape of the head and a particularly wide field of vision are achieved. In addition, correcting lenses (12) can be placed directly on the inner or outer limiting surface (16) of the eyeglasses (2). <IMAGE>
