Abstract:
1. A method of manufacturing an optical element, the optical element improving contrast sensitivity, low-contrast visual acuity, and vernier acuity in one or more eyes of a subject, the method comprising: obtaining a prescription for the one or more eyes, wherein the prescription comprises corrections for one or more high order aberrations in the subject's one or more eyes, wherein the prescription further comprises an aberration structure beyond a 3 mm diameter of the lens, wherein the aberration structure is selected to maximize a modulation transfer function (MTF) below a Nyquist resolution of the subject's one or more eyes, wherein a Nyquist resolution limit of the Nyquist resolution is a minimum visual acuity measured due to a cone density in a human fovea; applying the prescription to the optical element, wherein the optical element is configured for use with night vision goggles and further comprises a cured polymer, the cured polymer material comprising a fixed index of refraction, wherein the one or more high order aberrations are symmetrical high order aberrations, and wherein the method further comprises controlling limit aliasing in an image intensifier tube with a modulation transfer function.
