  • Patent number: 5096626
    Abstract: A plastic lens having a hard coat film and/or anti-reflecting film strongly adhered and having no defects such as yellowing, milky turbidities, cracks is provided. The plastic lens can be produced according to the present invention by forming an anti-reflecting film and/or a hard coat film on the working surfaces of a pair of molds, pouring a monomer liquid into the space between said molds and a ring gasket and polymerizing the monomer therein. Formation of the anti-reflecting film and/or the hard coat film can be carried out by coating of a hard coat solution or by a vacuum deposition of inorganic substances. When the anti-reflecting film and/or the hard coat film is formed by coating of a hard coat solution, a hard coat solution containing at least one release agent is applied to the working surfaces of the molds, or, after applying a release agent to the working surfaces of the molds, a hard coat solution containing no release agent is applied to the release agent layer.
