Abstract
A method of making an optical element that includes a thermoplastic power portion, the method including laminating a first thermoplastic sheet to one side of a functional film, laminating a second thermoplastic sheet to a second side of the functional film, and affixing either the first thermoplastic sheet or the second thermoplastic sheet to the power portion, with the other of the first or second thermoplastic sheets being open to atmosphere.
Claims21
An ophthalmic element comprising:
- a polymeric ophthalmic lens having a concave surface and a convex surface, and a laminate bonded to the polymeric ophthalmic lens, the ophthalmic element comprising, in the following order from a forward face of the element:
- a) an a bigradient interference layer having segments separated by a gap in the interference material between the segments of the bigradient interference layer,
- b) an organic polymeric hard coat layer extending across the gap in the interference material,
- c) a polymeric lens segment, and
- d) a polarizing layer.
