Two-Dimensional Biocompatible Plasmonic Lenses for Color Blindness Correction

Color blindness, or color vision deficiency (CVD), is an ocular disease that suppresses the recognition of different colors. Recently, tinted glasses and lenses have been studied as hopeful devices for color blindness correction. In this study, 2D biocompatible and flexible plasmonic lenses were fabricated using polydimethylsiloxane (PDMS) and an innovative, low-cost, and simple design based on the soft nano-lithography method. These lenses were investigated for correction of red-green (deuteranomaly) color blindness. The plasmonic lens proposed herein is based on the plasmonic surface lattice resonance (SLR) phenomenon and offers a good color filter for color blindness correction. The biocompatibility, low cost, and simple fabrication of these contact lenses can offer new insights for applications of color blindness correction.
