Abstract

A coated lens for use in a riflescope, telescope, spotting scope, binoculars, or the like is provided. The coating on the lens comprises two layers, an anti-reflective layer adjacent the lens and a hydrophobic layer disposed on the anti-reflective layer. The hydrophobic layer preferably includes an organosilane compound. Advantageously, the coating does not significantly reduce light transmission through the lens.

an anti-reflective layer comprising from about 3-7 sublayers, each of said sublayers comprising an anti-reflective composition; and

a hydrophobic layer on top of said anti-reflective layer, said hydrophobic layer comprising an organosilane compound,

said coating retaining at least 95% of a hydrophobic characteristic after undergoing a test comprising the steps of rubbing an eraser for at least 20 strokes along the same line using 2.5 pounds of pressure on the eraser, said hydrophobic characteristic being selected from the group consisting of a comparison of water contact angles before and after said test and a stain removal test using adhesive tape.
