Abstract
A method for making a hybrid lens includes providing, in a mold having a first Fresnel pattern, (i) a first lens and (ii) a silicone material comprising silicone and curing the silicone material in the mold to form a hybrid Fresnel lens. The cured silicone material is mechanically coupled with the first lens; and the cured silicone material has a second Fresnel pattern that corresponds to the first Fresnel pattern. A hybrid lens made by this method is also described. A hybrid lens includes a first lens mechanically coupled with a cured silicone material. The cured silicone material has a Fresnel pattern on a surface that faces away from the first lens.
