To provide a plastic lens which has more superior heat resistance that a conventional plastic lens with an antireflective film and also has sufficient antireflective performance and can easily be manufactured.
Plastic lens texture is provided with a primer coating, a hard coating, and further a low-refractive-index layer, ≥0.1 lower in refractive index than the hard coating, by a wet method to 50 to 150 nm thicknesses. Solved are problems in which a conventional plastic lens which is provided with an antireflective film by providing a multi-layered film composed of a plurality of inorganic oxides by vapor deposition or sputtering is inferior in heat resistance and a manufacturing device is large-sized and complicated since a vacuum process is needed.
