Abstract
The present invention relates to [1] a polymerizable composition for optical member containing a polymerizable component and a urethaneurea compound having a structural unit derived from tolylene diisocyanate in an amount of 0.1 to 10 parts by mass based on 100 parts by mass of a total amount of the polymerizable component; [2] a production method of an optical member, including a step of injecting the polymerizable composition of [1] into a molding die, and a step of polymerizing the polymerizable composition; and [3] a spectacle lens including a spectacle lens substrate obtained by the production method of [2].
