PROBLEM TO BE SOLVED: To improve manufacturing efficiency of silicone hydrogel more.SOLUTION: Silicone hydrogel is manufactured from polymerizable composition containing mono-functional monomer having a polymerization group and poly-functional monomer having multiple polymerization groups. The polymerizable composition comprises a hydrophilic compound having hydrophilic property, a silicone compound having oxygen permeability and an ultraviolet-absorbing polymeric compound as the mono-functional monomer and the poly-functional monomer, and there is a poly-functional monomer having a polymerization group same as that of the mono-functional monomer. A mol number A of acrylyl group of the mono-functional monomer, a mol number M of methacryloyl group of the mono-functional monomer, a mol number V of vinyl group and allyl group of the mono-functional monomer, a mol number a of acrylyl group of the poly-functional monomer, a mol number m of methacryloyl group of the poly-functional monomer and a mol number v of vinyl group and allyl group of the poly-functional monomer fulfill A>M and V>M, and both of A/a, M/m and V/v fulfill 10-180. |
