Method and jig for holding contact lens material, using light-scattering bonding adhesive

A method of holding a contact lens material having a concave surface while the contact lens material is processed into a contact lens, comprising the steps of:

• preparing a Jig including a protruding portion which has a top end having as an outer surface thereof a convex surface and a bottom end, said convex surface being adapted to be bonded to said concave surface of the contact lens material, said protruding portion having an inner surface that defines a recess which extends from said top end opposite said convex surface, toward the bottom end of the protruding portion, said inner surface including a first portion that corresponds to said convex surface of said top end of said protruding portion;
• applying an ultraviolet-curable bonding agent to at least one of said concave surface of said contact lens material and said convex surface of said protruding portion of said Jig;
• placing said contact lens material such that said concave surface of said contact lens material is in contact with said convex surface of said jig through said ultraviolet-curable bonding agent;
• and
• irradiating said ultraviolet-curable bonding agent through said jig via means for scattering light to cure said ultraviolet-curable bonding agent and thereby bond said contact lens material and said jig together, said means for scattering light comprising a roughed light-scattering texture along said first portion of said inner surface.
