[PROBLEMS] To provide a polymerizable composition which maintains a high refractive index and which is capable of suppressing cracks caused by high temperature history, peeling from the support, and dimensional change. [Solution] (a) 100 parts by mass of a specific reactive silsesquioxane compound, (b) 10 to 500 parts by mass of a specific fluorene compound, and (c) 0.1 to 50 parts by mass of a polymer having a weight average molecular weight of 5,000 to 100,000, a cured product obtained by polymerizing the polymerizable composition, and a material for a high refractive index resin lens comprising the polymerizable composition. |
