Abstract: A method is disclosed for imparting impact resistance to a plastic ophthalmic lens. The method consists of applying a coating of a multifunctional acrylate in a solvent mixture to the back surface of the lens, and curing the multifunctional acrylate to form an impact resistance imparting coat. The multifunctional acrylate preferably has at least about 40%, by weight, of a difunctional acrylate. The multifunctional acrylate preferably has a glass transition temperature less than about 60 DEG C. Lenses with an impact resistance imparting coat on the back, and an abrasion resistant coat on at least the front of the lens, are also disclosed.
