Abstract
In various embodiments, the present invention is directed to contact lenses that utilize a multilayer coating of alternating high RI materials, such as melanin or polydopamine (PDA) and other low RI materials to create tunable iridescent colors and contain melanin or similar materials that impart photoprotection due to their broadband UV-vis absorption spectrum and ability to quench radicals.
