New-generation of PDMS-based Lenses for Color Blindness management

Being a Color blindness or color vision deficiency (CVD) is a type of ocular disorder that prevents the recognizing the special colors. Until now, the certain cure for CVD has not been discovered. Recently, glasses and contact lenses based on chemical dyes were investigated as promising tools for color vision deficiency management. In this work, we proposed the plasmonic PDMS-based lenses to improve the red-green color vision deficiency. We utilized polydimethylsiloxane (PDMS) for fabricating the lens which is a biocompatible, nontoxic, stretchable, and transparent material and will be a suitable option for producing the contact lenses. Finally, the suggested contact lens based on PDMS was immersed in a HAuCl4·3H2O gold solution. Our suggested plasmonic lens is based on localized surface plasmon resonance (LSPR) effect and plasmonic gold nanoparticles dispersed in the produced contact lens based on PDMS suggest a suitable color filter for CVD improvement. The fabricated contact lens suggests perfect features including biocompatibility, durability, and stretchability, that will be helpful for color vision deficiency management.
