Abstract: Methods of shaping a glass sheet each include a step of removing a first portion of the glass sheet to form a first beveled surface. The methods further include the step of removing a second portion of the glass sheet to form a second beveled surface. The methods still further include the step of removing a third portion of the glass sheet comprising a remainder of an end surface of an edge portion of the glass sheet. In further examples, glass sheets are also provided with a first bevel surface intersecting a first glass-sheet surface and an apex surface, and a second bevel surface intersecting a second glass-sheet surface and the apex surface. The glass sheet exhibits a probability of failure of less than 5% at an edge stress of 135 MPa.

Abstract: Process for bevelling at least one edge (6) of an optical face (3) of an ophthalmic lens (1), which includes a plotting stage in which the successive curvatures of the optical face (3) are plotted in the vicinity of and along the edge (6) to be bevelled. In the plotting stage, the edge (6) to be bevelled is scanned by means of a flat light beam (23) forming a linear light spot (24) on the optical face (3), an image of the light spot (24) is simultaneously formed on optical reception means (26), the successive curvatures of the optical face (3) in the vicinity of the edge (6) are deduced from the successive positions of this image. This process includes a bevelling stage in which the lens (1), rotated about an axis (A1), is brought into contact by its edge (6) with a bevelling tool, and the relative positioning of the lens (1) and of the tool is controlled according to the plots produced.
