摘要： The present invention addresses the problem of providing a novel optical resin that retains favorable optical properties such as high refractive index, and at the same time has superior moldability that prevents molding defects from occurring. This problem is solved by an optical resin composition for lenses that contains a resin having a structural unit represented by formula (1), and a binaphthalene compound and/or a binaphthalene compound oligomer having a structural unit represented by formula (2). A, p, K 1 , K 2 , Z, and q in formula (1) are as described in the present specification. R 1 -R 10 , a, and b in formula (2) are as described in the present specification.
