[Problem] To provide a photochromic lens for eye glasses, which has a high refractive index and excellent light-controlling properties and has such a constitution that the weight and thickness of the lens can be reduced. [Solution] Provided is a photochromic lens for eye glasses, which is produced by polymerizing a polymerizable composition prepared by dissolving a photochromic compound into a monomer mixture comprising a first radically polymerizable monomer represented by general formula (I), a second radically polymerizable monomer represented by general formula (II) and divinylbenzene that has a purity of 50% or more and contains a divinylbenzene component and an ethylvinylbenzene component at a total content of 90% or more. |
