As one of the first companies to own the patent of spin casting for contact lenses, Horien is proud of its sophisticated spin casting and high-definition technology. After multiple times of purification, the liquid material is injected into a high speed spinning mold, where it is cured under ultraviolet light. Then after other processes such as edge refining, hydration and de-molding, the lens turns smooth and becomes the final product. It is superior in comfort and clarity.
