Disclosed is an optical resin composition containing (A) a first radical polymerizable component comprising at least one compound represented by formula (a1), etc., and (B) a second radical polymerizable component comprising a compound different from the first radical polymerizable component. When the first and second radical polymerizable components are radically polymerized, a resin material containing their polymers is formed, wherein the resin material has an Abbe number νd and a relative partial dispersion θg,F that satisfy the formulas 18 ≤ νd ≤ 25 and θg,F ≥ 0.700. [In formula (a1), at least one of X1, X4, or X5 is a group having a (meth)acryloyl group.] |
