A contact lens product includes a multifocal contact lens and a buffer solution. The multifocal contact lens is immersed in the buffer solution. The multifocal contact lens includes a central region and at least one annular region. The annular region concentrically surrounds the central region, and a diopter of the annular region is different from a diopter of the central region. The multifocal contact lens is made of silicone hydrogel or hydrogel. The annular region closest to a periphery of the multifocal contact lens is a first annular region.

Multifocal contact lens and contact lens product

A contact lens includes a central region, an annular region and a peripheral region. The central region includes a central point of the contact lens. The annular region symmetrically surrounds the central region. The peripheral region symmetrically surrounds the annular region. The peripheral region includes at least one color pattern portion. The annular region includes at least one power of critical point.
