The invention claimed is: 1. An optical lense comprising: a liquid thioether carboxylic acid ester, wherein the thioether carboxylic acid ester is a reaction product of A) a compound of the formula a) (A1) wherein R 1 is hydrogen, linear or branched C 1 -C 7 alkyl; R 2 is hydrogen or a linear or branched C 1 -C 8 -alkyl containing at least one sulfhydryl moiety (SH); R 3 and R 4 are independently selected from a linear or branched C 1 -C 8 -alkyl containing at least one sulfhydryl moiety (SH), and optionally one or two CH 2 group(s) of R 2 and/or R 3 and/or R 4 is/are replaced by O, S and/or C═O and B) a compound of the formula (B) wherein Y is hydrogen or methyl; Z is O; R 5 is a linear or branched saturated C 1 -C 8 alkyl or a saturated bicyclic aliphatic system selected from the group consisting of norbomyl-, isonorbornyl-, pinenyl-, menthyl-, camphyl- or an aryl system selected from phenyl and benzyl. 2. The optical lense according to claim 1 , wherein in the formula (A1) R 1 is hydrogen or ethyl; R 2 is hydrogen or a linear C 1 -C 6 -alkyl containing at least one sulfhydryl moiety (SH); R 3 and R 4 are independently selected from a linear C 2 -C 6 -alkyl containing at least one sulfhydryl moiety (SH), and one or two CH 2 group(s) of R 2 and/or R 3 and/or R 4 is/are replaced by 0, S and/or C═O. 3. The optical lense according to claim 1 , wherein in the formula (A1) R 1 is hydrogen; R 2 is a linear C 1 -C 5 -alkyl containing at least one sulfhydryl moiety (SH); R 3 and R 4 are independently selected from a linear C 3 -C 5 -alkyl containing at least one sulfhydryl moiety (SH), and one CH 2 group of R 2 and/or R 3 and R 4 is replaced by S. 4. The optical lense according to claim 1 , wherein in the formula (A1) R 1 is hydrogen or ethyl; R 2 is hydrogen or a linear C 3 -C 5 -alkyl containing at least one sulfhydryl moiety (SH); R 3 and R 4 are independently selected from a linear C 3 -C 5 -alkyl containing at least one sulfhydryl moiety (SH), and two CH 2 groups of R 2 and/or R 3 and R 4 are replaced by O and C═O. 5. The optical lense according to claim 4 , wherein two CH 2 groups of R 2 and/or R 3 and R 4 are replaced by O and C═O, and O and C═O are directly linked. 6. The optical lense according to claim 1 , wherein Y is hydrogen or methyl; Z is O; R 5 is linear saturated C 1 -C 3 alkyl. 7. The optical lense according to claim 1 , wherein Y is hydrogen or methyl; Z is O; R 5 is a linear or branched saturated C 1 -C 4 alkyl or a saturated bicyclic aliphatic system selected from the group consisting of norbornyl-, isonorbornyl-, pinenyl-menthyl-, camphyl- or an aryl system selected from phenyl and benzyl. 8. The optical lense according to claim 1 , wherein the reaction product is obtained by a 1,4-addition mechanism of the at least one sulfhydryl group of the compound of the formula (A1) and the compound of the formula (B). 9. The optical lense according to claim 1 , wherein the reaction product is of the general formula (C1) wherein Y, Z, and R 5 are as defined in claim 1 and wherein A 1 is (A1) as defined in claim 1 . 10. The optical lense according to claim 1 , wherein the thioether carboxylic acid ester has a refractive index of 1.27-1.9, and/or an Abbe's number of 35-110.
