About SEED AS-LUNA

Good to know

Design and material

High oxygen permeability. SEED AS-LUNA material has a Dk value of 156. The Dk value is the rate that oxygen can flow through a material.
Natural aspheric design. The well-balanced aspheric design has a base curve approximated to the shape of the cornea, so the Lens is fitted to the cornea more gently than spherical Lenses and is stylishly thin.
Flexible RGP material. Polymer alloy technology makes the high Dk material tough. When a 5.4 g iron ball was dropped onto Lenses, SEED AS-LUNA broke at a height of 150 cm, against 20 to 30 cm for the other high Dk Lenses tested.
