Abstract

A method for manufacturing colored contact lenses having dazzling appearance, comprises: preparing color component that is applied to a concave mold wherein a pattern is formed on its surface; pouring specified amount of liquid lens material into the mold; and spinning the mold at specified speed to form curvature on the surface; and solidifying the lens material and the color component; the color material shift while the mold spins to form dazzling pattern.
