Abstract
The present invention is an anti-reflective transparent article which includes a transparent substrate. The article also includes a first coating of metal oxide applied over the substrate. The first coating of metal oxide has a reflective index of about 1.8 to about 2.6. The article further includes a second coating of a metal oxide applied over the first coating of metal oxide. The second coating has a refractive index of about 1.44 to about 1.6. The reflectivity of the article, when measured at an angle of at least 50 degrees from normal, is at least three percentage points less than the reflectivity of the uncoated substrate at the same angle.
