1-23. (canceled)
A reactive monomer mixture for making an ophthalmic lens, the reactive monomer mixture comprising:
- a monomer suitable for making the ophthalmic lens;
- a first polymerization initiator capable of being activated at a first wavelength;
- a first functional moiety chemically linked to the first polymerization initiator;
- and
- a second polymerization initiator that is capable of being activated by a second activation that does not substantially activate the first polymerization initiator.
