Abstract
A method for forming optical elements at a surface of an ophthalmic lens including a lens material includes providing a laser interaction layer at a surface of the ophthalmic lens, the laser interaction layer including a first material having a first absorption of radiation at a first wavelength, λ1, the lens material having a second absorption of radiation at λ1, the second absorption being lower than the first absorption, exposing discrete areas of the laser interaction layer to laser radiation at λ1 sufficient to form an optical element at each discrete area in the lens material.

A method for forming optical elements at a surface of an ophthalmic lens comprising a lens material, the method comprising:
- providing a laser interaction layer at a surface of the ophthalmic lens, the laser interaction layer comprising a first material having a first absorption of radiation at a first wavelength, λ1, the lens material having a second absorption of radiation at λ1, the second absorption being lower than the first absorption;
- and
- exposing discrete areas of the laser interaction layer to laser radiation at λ1 sufficient to form an optical element at each discrete area in the lens material.
An ophthalmic lens, comprising:
- a lens material having opposing curved surfaces shaped to provide a base curvature of the ophthalmic lens, the opposing curved surfaces comprising a first surface;
- a plurality of optical elements arranged in a pattern at the first surface, the optical elements corresponding to regions having a refractive index different from a refractive index of the lens material and/or a surface shape different from a curvature of the first surface;
- and
- a laser interaction layer at the first surface, the laser interaction layer comprising a first material having a first absorption of radiation at a first wavelength, λ1, the lens material having a second absorption of radiation at λ1, the second absorption being lower than the first absorption.
