1. A method for producing a glass article, the method comprising:
preparing a glass to be processed, the glass comprising a glass bulk and a low-refractive surface layer disposed on the glass bulk, the low-refractive surface layer having a lower refractive index than a refractive index of the glass bulk; and
polishing a surface of the glass to form a polished glass,
wherein the polishing the surface of the glass comprises: removing at least partially the low-refractive surface layer, and
wherein the polished glass, after the polishing of the surface of the glass, includes an upper surface and a lower surface both of which the low-refractive surface layer does not remain on.
 
14. A method for producing a glass article, the method comprising:
preparing a glass to be processed that has a first surface and a second surface opposed to the first surface, wherein the glass has a first maximum compressive stress at the first surface and a second maximum compressive stress at the second surface; and
polishing the first surface or the second surface to reduce deviations between the first maximum compressive stress and the second maximum compressive stress,
wherein the glass has no optical interface from the first surface to the second surface after the polishing.
