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.
