| titleOfInvention | Manufacturing method of soft contact lens |
| abstract | 【Task】 It has been demanded to prevent the occurrence of defects due to lens dents caused by polymerization shrinkage in the polymerization stock solution of the hydrophilic component being a monomer and the hydrophobic component being a copolymer. Therefore, in the present invention, polymerization shrinkage is suppressed, the formation of dents is prevented, and the yield of products is improved. [Solution] A method for producing a soft contact lens by heating and polymerizing a polymer containing (meth) acrylic acid ester as a monomer and a stock solution containing a hydrophilic monomer having a polymerizable group, and heating for up to 4 hours after the start of heating A method for producing a soft contact lens, characterized in that the total temperature is 130 ° C. · h or more and 150 ° C. · h or less, and there is no polymerization shrinkage after polymerization and no appearance defects. 【effect】 According to the present invention, the occurrence rate of defects due to lens dents becomes 0%, and the yield of products can be improved.
