Abstract: An imaging camera device comprising (1) an image sensor, (2) a spherical-power adapter coupled to the image sensor, wherein the spherical-power adapter moves the image sensor relative to an imaging lens, (3) a field-curvature adapter coupled to at least one optical component placed between the image sensor and the imaging lens, wherein the field-curvature adapter adjusts the size of a variable air gap formed between the optical component and at least one additional optical component, and (4) a cylindrical-power adapter that includes a plurality of cylindrical correction lenses applied to a wheel configured to rotate in at least one direction. Various other apparatuses, systems, and methods are also disclosed.

Abstract: A lens assembly includes an optical element having an outward-facing surface with a cornea-shaped contour. The lens assembly includes a housing that carries an optical element. The housing at least partially houses an image sensor. The image sensor is positioned to receive image light from the optical element. The lens assembly is an artificial eye system that may be used to mimic a human eye while operating or testing a head-mounted display.
