Abstract
Abstract Coated lenses are provided that are suitable for optical and ophthalmic applications that include a coating for providing wear resistance and filtering of electromagnetic radiation in the range of from ultraviolet to about 500 nanometers or higher. The coating comprises carbon and hydrogen and is preferably formed by a glow discharge deposition process.
