Abstract

PURPOSE: To uniformly impart extremely high oxygen permeability to the entire contact lens without deteriorating the optical and mechanical characteristics.
CONSTITUTION: The contact lens 1 has many through-holes 2 having ≤100μm diameter. The through-holes are substantially directed perpendicularly to the lens surface 1a, and radially arranged from the center of the semisphere forming the lens surface 1a.
