Abstract

There is provided a polymerizable composition suitable to produce a molded product in which high refractive index is maintained, and dimensional change and a transmittance change further caused by a high-temperature heat history can be suppressed. A polymerizable composition comprising (a) 100 parts by mass of a specific reactive silsesquioxane compound and (b) 10 to 2,000 parts by mass of a specific fluorene compound, and a cured product obtained by curing the polymerizable composition, and a resin lens manufactured from the polymerizable composition.
