Disclosed is a method for producing a plastic lens having reflow heat resistance at 260° C., which is characterized in that a photosensitive resin composition containing a specific resin and a photopolymerization initiator is molded into a lens shape. The resin is obtained by mining one or more compounds (a) selected from the group consisting of (CH3O)3—Si—(CH2)3—O—CO—C(CH3)═CH2, (CH3O)3—Si—(CH2)3—O—CO—CH═CH2, (CH3O)3—Si—(CH2)x—CH═CH2 (wherein X is 1 or 2), (CH3O)2—Si(CH3)(CH2)3—O—CO—C(CH3)═CH2, (CH3O)2—Si(CH3)(CH2)3—O—CO—CH═CH2 and (CH3O)2—Si(CH3)—(CH2)x—CH═CH2 (wherein X is 1 or 2) with a compound (b) represented by (C6H5)2—Si—(OH)2 such that 50-150 moles of the compounds (a) is mixed per 100 moles of the compound (b), and then polycondensing the mixture at 40-15° C. for 0.1-10 hours in the presence of a catalyst.
