Menifocal Z

Menifocal Z is basically a concentric design, which has a central optical zone for distance and peripheral optical zone for near vision.

The unique transition zone allows for the reduction of blurring and double vision.

Menifocal Z also utilizes an aspherical front surface that contributes to providing effective ADD power, while the spherical back surface allows for easy fitting.

Similar or better distance vision and comfort than normal GP contact lenses

Menifocal Z has the distance optical zone in its center.

This provides similar distance vision to normal contact lenses. The Menifocal Z design strives to ensure a maximum bifocal effect without losing the original advantages of GP lenses. Menifocal Z incorporates uniquely advanced optical zones bound together with a unique transition zone.

Distance vision

The rays passing through the center optical zone can be focused at the retina. The distance optical zone is set centrally in order to cover the pupil when looking straight- ahead, which results in clear distance vision.

Near vision

The peripheral optical zone contains the reading ADD power. The lens adjusts downward gazing for near vision. The near optical zone can cover the pupil, which results in clear, near vision.

Material

The Menifocal Z lens material is a polymer composed of fluoro-methacrylate and a siloxanylstyrene, which ensures the highest level of oxygen to the cornea, Hyper Dk.

No other bifocal contact lens is currently able to supply oxygen to the cornea at this level.

Menifocal Z is approved for up to 30 days continuous wear under the supervision of an eye-care professional.

Dk/L(Dk/t), Oxygen Transmissibility

The hyper Dk value of the material of Menifocal Z lenses combined with the thin design further enhances oxygen transmissibility.

Menicon Z, which has already been launched in an aspheric design, is the first material to be classified in the "hyper-oxygen transmissibility" category by Dr. Joe Benjamin, a leading expert in the field of researching the oxygen transmissibility of contact lenses.

UV Filter

Menifocal Z contains benzotriazol, an ingredient that absorbs ultraviolet light.

The Menifocal Z material blocks over 90% of harmful UVA and UVB rays from the light entering the eyes.
