Coated articles demonstrating anti-reflective properties are provided. Exemplary coated articles comprise a substrate and an anti-reflective coating layer applied to at least one surface of the substrate. The anti-reflective coating layer is formed from an acidic sol-gel composition comprising: (a) tetraalkoxysilane; (b) alkyl trialkoxysilane; (c) a silane-functional acrylic polymer; (d) inorganic oxide particles; (e) a mineral acid; (f) water; and (g) a solvent. The coated article optionally further comprises an outermost anti-fouling coating layer applied to at least one surface of the anti-reflective coating layer.
