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, λ, the lens material having a second absorption of radiation at λ, the second absorption being lower than the first absorption, exposing discrete areas of the laser interaction layer to laser radiation at λsufficient to form an optical element at each discrete area in the lens material.
