Jig for holding contact lens material, using light-scattering bonding
adhesive
Abstract:
A jig adapted to hold a contact lens material having a concave surface, for holding the contact lens material, including a protruding portion which has a top end having as an outer surface thereof a convex surface. This convex surface of the jig is bonded to the concave surface of the contact lens material. The protruding portion has a recess which extends from an inner surface of the top end toward a bottom end of the protruding portion. The recess is defined by an inner surface which includes a first portion that corresponds to the convex surface of the top end of the protruding portion. At least the first portion of the inner surface is roughened with a light-scattering texture. A method of holding the contact lens material while the contact lens material is processed into a contact lens is disclosed.
