Abstract:
A method for layering lenses includes: plasma treating a lens surface; applying a removable ink layer onto the lens surface; applying a base ink layer over the removable ink layer; applying at least one colored ink layer over the base ink layer; and removing the removable ink layer. Additional steps may include drying the lens, sealing the sides of the lens, and applying liquid to the lens before removing the removable ink layer.
