摘要： A method of making a customized lens includes providing a first substrate having a first surface, the first surface being a non-flat surface; placing an optical film in contact with the first surface; bringing a layer of a first material into contact with the optical film; and curing the layer of the first material to form a lens. The optical film has a lower surface roughness than the first surface.

摘要： A method is presented herein for manufacturing an immersed Fresnel structure. A first liquid polymer is applied to a first surface of a substrate, the substrate having a second surface that is opposite the first surface. The first liquid polymer is illuminated with light to change at least one property of the first liquid polymer and obtain a modified polymer attached to the first surface of the substrate. A second liquid polymer is applied to at least a portion of a surface of a Fresnel structure. The second surface of the substrate is applied to an outer surface of the second liquid polymer applied to the Fresnel structure to obtain a stacked Fresnel surface. The stacked Fresnel surface is illuminated with light to obtain an immersed Fresnel structure. The immersed Fresnel structure can be used as part of a near-eye display.
