Abstract
In this work we present the design of a novel ophthalmic prismatic contact lens to correct for
strabismus. Strabismus, colloquially called "crossed-eyes" or "wall eyes," is a condition in which the
eyes are not properly aligned with each other. To our knowledge there are no contact lenses that
allow for strabismus correction. To address this, we have designed a poly methyl methacrylate
(PMMA) based prismatic correction contact lens. Therefore, we modeled a Fresnel lens with the
appropriate optical properties and a human eye in COMSOL Multiphysics Ray Optics module. Our
first design was created by mapping Fresnel lenses onto the curved surface of the eye, the focus of
light on retina was suboptimal. Next we determined two more potential solutions and improved the
light focus on the retina but there were still some issues. A small fraction of light (~5%) diverged
and could not be focused. Due to dispersive characteristic of PMMA, chromatic aberration was
present. We will use our ray optics solution and convert into a metasurface nanophotonic lens that
has the identical behavior and mitigates the issues related with prismatic lens.
