Abstract: A coating for an optical article, such as a lens, includes a bottom coating having at least one hydrophilic resin binder and at least one surfactant, forming an anti-fogging layer, and a top coating overlying the bottom coating, forming an anti-reflective layer. The top coating includes nanopores, which may be less than 150 nm in size.

Abstract: Anti-reflective (AR) coatings and methods for applying AR coatings to substrates, such as optical lenses. The coating may include a polyurethane base layer and a fluoropolymer top layer. The base layer may protect the underlying substrate, promote adhesion between the top layer and the underlying substrate, and achieve index-matching with the underlying substrate. The method may involve an inexpensive and efficient solution coating process.
