Menicon Z-α Design

Unique design factors

1. Easy to fit on 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 fit your cornea configuration naturally for comfort.

2. Good Centering

Menicon Z-α is designed with a consideration for stability of fit and to allow the upper eyelid to move easily pull the lens back up by thinning the central part of the contact lenses and thickening the periphery. This holds potential for lowering the incidence of 3 and 9 o'clock corneal staining.

3. More comfortable

Setting an optic zone diameter of 7.6mm* makes it possible to deal with lens movement and pupil changes. (* on as 8.8mm diameter lens)
