  [Problem] To provide plastic lenses for spectacles, having a high refractive index and a high Abbe's number, and having good transparency, heat resistance, mechanical strength and impact resistance. [Means for Resolution] Provided are plastic lenses for spectacles, which are produced through polymerization of an epithio group-having compound (a), a polythiol compound (b) and a polyisocyanate compound (c) whereby the ratio of the polythiol compound (b) to the polyisocyanate compound (c) is at least 2.0 in case of a sulfur-free polyisocyanate compound (co) and is at least 1.2 in case of a sulfur-containing polyisocyanate compound (cs), calculated on the basis of mol-amounts of -SH and -NCO groups The invention also provides a process for preparing such lenses and a catalyst for use in said process.

  A poly(thio)ester (co)polymer which comprises a repeating structural unit represented by the formula (1-A) as an essential structural unit: [wherein R11 is a divalent aliphatic hydrocarbon group which may contain at least one sulfur atom in a sulfide group; R12 is a mono- or poly-cyclic aliphatic or aromatic dicarboxylic acid residue; and X11 and X12 are each independently an oxygen atom or sulfur atom, and when X11 and X12 are the oxygen atoms, R11 is a divalent aliphatic hydrocarbon group containing at least one sulfur atom in the sulfide group]; and an optical component obtainable by molding the poly(thio)ester (co)polymer. The poly(thio)ester (co)polymer is excellent in transparency and optical characteristics (e.g., a higher refractive index, higher Abbe number, and lower birefringence), and has also good mechanical characteristics and thermal characteristics, and further is excellent in melt fluidity and injection moldability.
