Textured, antiglare glass articles and methods of making the same

A glass article, comprising:

• a glass substrate comprising a thickness and a primary surface;
• and
• a textured region defined by the primary surface,
• wherein the textured region comprises a low spatial frequency region and a high spatial frequency region,
• wherein the low spatial frequency region comprises an average lateral feature size that exceeds an average lateral feature size of the high spatial frequency region,
• wherein the textured region comprises a surface roughness (Ra) from about 10 nm to about 1000 nm, and
• further wherein the glass article comprises a sparkle of less than 3% as measured by pixel power distribution (PPD) and a distinctness of image (DOI) of less than 70%.

A method of making a glass article, comprising:

• a first etching of a primary surface of a glass substrate with a first etchant to form a low spatial frequency textured region defined by the primary surface;
• and
• a second etching of the primary surface of the glass substrate with a second etchant to form a high spatial frequency textured region defined by the primary surface and substantially superimposed within the low spatial frequency textured region,
• wherein the low spatial frequency textured region comprises an average lateral feature size that exceeds an average lateral feature size of the high spatial frequency textured region, and
• further wherein the textured regions comprise a surface roughness (Ra) from about 10 nm to about 1000 nm.
