Title: METHOD FOR MANUFACTURING CONTACT LENS
Abstract:
This method is for manufacturing a contact lens by taking out, from a pair of dies, a contact lens produced by polymerizing monomers included in the pair of dies obtained by assembling a lower die forming the front curve of the contact lens and an upper die forming the base curve of the contact lens, the method comprising: (A) a first detachment step for detaching the contact lens from a lens forming surface of the upper die; (B) a separation step for separating the lower die to which the contact lens is attached, from the upper die; (C) a second detachment step for detaching the peripheral part of the contact lens attached to the lens forming surface of the lower die; and (D) a third detachment step for detaching the contact lens of which the peripheral part has been detached from the lens forming surface of the lower die.
