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.
