The present invention is directed to an eyewear material comprising a polyurethane resin produced by allowing a polyisocyanate component to react with an active hydrogen group-containing component, wherein the polyisocyanate component comprises 1,4-bis(isocyanatomethyl)cyclohexane comprising 70 mol% or more and 95 mol% or less of a trans isomer relative to a total amount of a cis isomer and the trans isomer, and 0.1 ppm or more and 300 ppm or less of a compound represented by formula (1) below: and/or a polyisocyanate composition produced by modifying the 1,4-bis(isocyanatomethyl)cyclohexane and contains at least one functional group of (a) to (e) below: (a) an isocyanurate group, (b) an allophanate group, (c) a biuret group, (d) a urethane group, and (e) a urea group.
