With α design, more people can now wear contact lenses. Menicon Z-α, high-oxygen-permeable GP Lenses.
World-class lens material, Menicon Z material.
Z material is a high-oxygen-permeable material that is safe for your eyes. The toughness of the material makes it possible to manufacture this design. The material also contains a UV absorber to absorb harmful ultraviolet light.
α design provides comfortable eye sight.
α design provides good centering and optical tear exchange with comfortable eyesight and wide optical zone.
Menicon Z-α Design
1. Easy to fit onto the cornea
The lens has a central spherical zone and an aspheric periphery. Similar to the inner surface configuration of Menicon Z-α, a central spherical and aspheric periphery are utilized, which makes it possible to naturally and comfortably fit your cornea configuration.
2. Good Centering
Menicon Z-α is designed with consideration for stability of fit and to allow the upper eyelid to move easily. The thin central part of the contact lenses and the thick the periphery pull the lens back up. This holds potential for lowering incidences of 3 and 9 o’clock corneal staining.
3. More comfortable
Setting an optic zone diameter of 7.6 mm* makes it possible to address lens movement and pupil changes (*on a 8.8 mm diameter lens).
