Description

technical field [0001] The present invention relates to a resin composition for a high-refractive-index optical lens having excellent impact resistance, a high-refractive-index optical lens using the above-mentioned composition, and a method for producing the same, especially for processing with excellent lightness, plasticity, and dyeability. High-refractive-index optical lens with excellent impact resistance and high heat resistance of solid resin in addition to optical properties such as high Abbe number and transparency. Using a resin composition, a high-refractive-index optical lens with excellent impact resistance utilizing the above-mentioned composition and a manufacturing method thereof. Background technique [0002] Glass lenses, which have been widely used as optical lenses since a long time ago, have a small thermal expansion coefficient, so the change of the lens power with the change of the external temperature is small, and the multilayer film coated on the su...
