Abstract
A contact lens system for monitoring ocular diseases includes a smart phone camera and a nanostructured contact lens. The nanostructures can cause visible color shifts from optical reflection in response to a physical surface curvature change of the contact lens. The physical surface curvature change of the contact lens can be detected by visible color shifts on a range of about 8° at normal room light. An embodiment of the contact lens can detect a change in the diffraction angle of light passing through the lens. A change in the diffraction angle can be correlated with can indicate a change in a hydration level of the ocular surface and/or Kion concentration change.
