Paper Abstract

The design proposed in this abstract, for a monocular see through smart glass, i.e. Design Challenge #1, leverages a varifocal lens to accommodate human eyes with different focusing abilities. The eyepiece is made of three separate segments. The varying focus of the system is achieved by using two freeform Alvarez surfaces. The Alvarez lens proposed here has the advantage of achieving different focal lengths by laterally shearing the optics with respect to each other. As a proof of concept, it is shown that the Alvarez lenses provide the ability of a constant performance for different eye conditions.
