| titleOfInvention | Colorless spectacle lens |
| abstract | (57) Abstract: A combined spectacle lens 10 having improved chromatic aberration characteristics is provided, and the lens 10 includes a polymer resin layer lens 20 and a base lens 30. The chromatic dispersion characteristics of the resin layer 20 and the refractive index thereof are adapted to the base lens 30 to obtain the desired Abbe number, lens refractive power and lens thickness of the finished lens 10, and polymerize with the base lens 30. The boundary surface between the resin layer lens 20 and the resin layer lens 20 is almost indistinguishable. The chromatic dispersion characteristics of the base lens 30 are corrected by the polymer resin layer lens 20, and the polymer resin layer lens 20 has a relatively low Abbe number and has a constant refractive power opposite to that of the base lens 30. are doing. |
