[PROBLEMS] To provide an actinic-energy-ray-curable composition for optical materials which can give a cured article having a high refractive index, high light transmittance, and low water absorption. [MEANS FOR SOLVING PROBLEMS] The actinic-energy-ray-curable composition for optical materials comprises (A) a di(meth)acrylate represented by the formula(1) and (B) a mono(meth)acrylate represented by the formula (2) and/or mono(meth)acrylate represented by the formula (3). Also provided is a process for producing an optical material which comprises applying or pouring the composition to a casting mold and then irradiating it with actinic energy rays. [R1 and R3 each independently represents hydrogen or methyl; R2 and R4 each independently represents hydrogen, methyl, or ethyl; R5 to R8 each independently represents hydrogen, methyl, or bromine; and l and m each independently is an integer of 1 to 6.] [R9 represents hydrogen or methyl.] [R10 represents hydrogen or methyl.]
