A contact lens product comprises a multifocal contact lens and a buffer solution, the multifocal contact lens being immersed in a buffer solution. The multifocal contact lens comprises a central zone and at least one annular zone, the annular zone concentrically surrounding the central zone, the diopter of the annular zone being different from the diopter of the central zone, the buffer solution comprising a ciliary muscle paralysis agent. In this way, contact lens products can prevent myopia or control the progression of myopia. |
