An embodiment of the present disclosure relates to a method for producing an optical component resin having excellent dyeability, an optical component resin, a spectacle lens, and spectacles. A method for producing an optical component resin, including a step of polymerizing a polymerizable composition containing a polyisocyanate component and a polythiol component containing 40 mol % or more of a polythiol compound having two or more sulfide bonds in a molecular structure thereof, in which the content of a hydrolyzable chlorine compound contained in the polyisocyanate component is in a range of 10 ppm by mass or more and 100 ppm by mass or less in the polyisocyanate component, an optical component resin obtained by the producing method, an optical component formed of the optical component resin, a spectacle lens including a lens substrate formed of the optical component resin, and spectacles including the spectacle lens.
A method for producing an optical component resin, comprising
An optical component resin which is a polymer of a polyisocyanate component and a polythiol component containing 40 mol % or more of a polythiol compound having two or more sulfide bonds in a molecular structure thereof, wherein
