A non-hydrous soft contact lens comprising a copolymer comprising, as monomer units, 49.9 to 95 mole % of an acrylate represented by Formula (I) shown below, 0 to 10 mole % of acrylic acid or the specified ester thereof, 4.9 to 50 mole % of a methacrylate represented by Formula (II) shown below, and 0.1 to 10 mole % of a crosslinking monomer.
wherein R1 is at least one selected from the group consisting of a particular straight chain fluoroalkyl group and a particular straight chain alkyl group.
wherein R2 is a particular straight chain fluoroalkyl group.
The present soft contact lens requires no sterilization by boiling, and has good resistance to stain, good oxygen premea- bility, good elastic recovery and good shape stability.
A process for producing the above non-hydrous soft contact lens to treatment(s) of esterification and/or transesterification, is also disclosed.
