Abstract
A smart contact lens includes a contact lens, a nanostructures layer, a first sensor, a connector, and a smart module. The nanostructures layer may be anti-bacterial. The smart contact lens may be worn on an eye or may be implanted within an eye. The nanostructures layer is fabricated by depositing a colloidal dispersion onto an electrostatically-coated substrate. The colloidal dispersion is then removed and nanoholes are etched. The electrostatic coating is removed and a biocompatible material is spin-coated onto the substrate. Upon removal, a quasi-randomly distributed nanostructures layer forms.
