Abstract
An optical element includes a first lens; a cover; and a cured matrix polymer sandwiched between the first lens and the cover; the matrix polymer, prior to curing, having a monomer mixture dispersed therein; the matrix polymer being selected from the group consisting of polyester, polystyrene, polyacrylate, thiol-cured epoxy polymer, thiol-cured isocyanate polymer, and mixtures thereof; and the monomer mixture comprising a thiol monomer and at least one second monomer selected from the group consisting of ene monomer and yne monomer.
Claims20
An optical element, comprising:
- a first lens blank;
- a cover;
- a thiol-cured epoxy matrix polymer sandwiched between the first lens blank and the cover, wherein the thiol-cured epoxy matrix polymer is produced by crosslinking an epoxy polymer and a thiol monomer by utilizing a cross-linking agent, wherein the thiol-cured epoxy matrix polymer further comprises an ene monomer and thiol monomer;
- a low order prescription generated on the back surface of the first lens blank, wherein the low order prescription is specific to a patient's eye;
- and
- a crosslinked ene-thiol polymer that is produced by radiation curing the ene monomer and thiol monomer that are dispersed in the thiol-cured epoxy matrix polymer.
A method of making an optical element, the method comprising:
- selecting a first lens blank;
- selecting a second lens blank;
- sandwiching a pourable matrix polymer and monomer mixture between the first lens blank and the cover, wherein the matrix polymer comprises an epoxy polymer and the monomer mixture comprises a thiol monomer, a crosslinking agent, and an ene monomer;
- forming a gelled mixture of the matrix polymer and the thiol monomer by utilizing the crosslinking agent to produce a thiol-cured epoxy polymer;
- generating the second lens blank to make a cover;
- generating patient's eye specific low order prescription in the first lens blank;
- and
- forming a cured film by radiation curing the ene monomer and thiol monomer to form a crosslinked ene-thiol polymer that is dispersed in the matrix polymer.
