An object of the present invention is to provide a hydrophilic silicone containing a predetermined number of silicon atoms, having a high purity and suitable as a monomer for producing an ophthalmic device, and a method for producing the same. A monomer for producing an ophthalmic device, comprising a silicone compound represented by the formula (1) in an amount of more than 95% by weight of the monomer. (Where m is one of integers of 3 to 10, n is one of integers of 1 to 10, R 1 is one of alkyl groups having 1 to 4 carbon atoms, and R 2 is hydrogen. And one of methyl groups) [Selection figure] None |
