摘要： Embodiments of an anti-glare article and methods for forming the same are disclosed. In one or more embodiments, the anti-glare article includes a substrate having a surface, and a plurality of features disposed on the surface, wherein about 50% or more of the plurality of features comprise a normalized area in the range from about 0.5 to about 1.5, and the normalized area is defined as the relationship (surface area of a feature/average surface area of all features). In some embodiments, about 90% or more of the features have a surface area of about 100 micrometers or less. The anti-glare article exhibits a PPDr of about 5% or less, a transmission haze of less than about 20% and a DOI of less than about 90%. Methods of forming the substrate are also disclosed and include etching a surface of a substrate with an etchant comprising a water soluble metal ion salt.
