Could gold nanocomposite lenses help manage color blindness?

Researchers from Khalifa University (Abu Dhabi, United Arab Emirates) and Imperial College London (UK) have described integrating gold nanoparticles into contact lens material, creating nanocomposite contact lenses with potential applications for helping manage red–green color vision deficiency. Red–green color blindness is the most common form of color vision deficiency, which affects protans and deutans. There is no cure for this color blindness and affected individuals may wear tinted glasses or lenses that aim to enhance their color perception; however, such wearables cannot correct for blurry vision. Studies have previously sought to investigate the fabrication of contact lenses for color vision...
