Z Material

Through years of research and development, a new material of contact lens has emerged. The material named Z Material balanced the two key factors: strength of the material and high oxygen permeability. Menicon Z material is the world first Hyper Dk GP lens material approved by FDA up to 30 days continuous wear.

Z Material is a hyper-oxygen permeable gas permeable lens that offers comfort, wettability, long term eye health and clear crisp vision with the highest level of oxygen permeability in a gas permeable lens material available today.


Z Material is a new polymer with novel components syloxanylstyrene, fluoromethacrylate and benzotriazol UV absorber which makes it stronger, allowing the lens to be made thinner than a typical gas permeable lens thus providing more comfort.

Compared to other high oxygen permeable materials, Z Material offers excellent deposit resistance, extraordinary levels of oxygen permeability and also higher resistance to breakage and scratches. While maintaining excellent stability and wettability, it can be manufactured in thin designs enabling wearers to enjoy exceptional vision and comfort.
