`
`1.
`
`(Original) An eyeglass lens prepared using a resin composition comprising at least one
`
`isocyanate
`
`compound
`
`selected
`
`from
`
`a
`
`group
`
`consisting
`
`of
`
`2,5-
`
`bis(isocyanatomethyl)bicyclo[2.2. 1]heptane and 2,6-bis(isocyanatomethyl)bicyclo[2.2. 1]heptane,
`
`a polythiol compound, an ultraviolet absorber represented by formula (1), and an ultraviolet
`
`absorber represented by formula (2), wherein the eyeglass lens has an M value represented by the
`
`following formula (X) greater than 0.7 and less than 16.7.
