Abstract
A method comprises: disposing a measurement contact lens upon an eye of a user; capturing at least one image of the eye and the measurement contact lens with an image sensor while the measurement contact lens is on the eye of the user and the eye is illuminated; processing the at least one image to obtain a centration of the measurement contact lens on the cornea of the eye; processing the at least one image to obtain an angular orientation of the measurement contact lens on the cornea of the eye; and determining, based on the centration and angular orientation of the measurement contact lens on the cornea of the eye, at least one parameter of a first contact lens to be worn on the eye with display eyewear or a second contact lens to be worn on the eye without the display eyewear.
