A glass sheet comprising at least one etched surface having a surface roughness defined, when measured on an evaluation length of 2 mm and with a Gaussian filter of which the cut-off wavelength is 0.8 mm, by 0.02Ra0.4 microns and 5RSm30 microns. The glass sheet has excellent anti-sparkling properties together with an anti-glare effect. The texturing of the glass sheet may obtained by the process of carrying the glass sheet horizontally on a conveyor, pre-treating the surface to remove defects that may prevent subsequent uniform etching, etching the surface with aqueous solution containing hydrofluoric acid spread in an uniform layer over the surface of the sheet, maintaining the etching solution until the etching is ended, and drying the etched sheet.
