[PROBLEMS] To provide an ophthalmic solution that is transparent, has low adhesiveness, is safe without being adsorbed on the cornea when worn, has excellent operability, and has excellent shape stability due to an appropriate balance of strength, flexibility, and elasticity. Provide lens material. A compound (A) having a group containing an ethylenically unsaturated group and a polydimethylsiloxane structure via a urethane bond, general formula (1) or (2): And an alkoxy group-containing acrylate (B) represented by the general formula (3): (Wherein X is an oxygen atom or a direct bond), which is a copolymer component containing phenylalkyl acrylate or phenoxyalkyl acrylate (C), stress in a tensile test at 35 ° C. is 0.1 to 10 MPa, elongation rate Is an ophthalmic lens material having a Young's modulus of 0.4 to 3.0 MPa.
