Abstract
A method comprises capturing at least one image of an eye of a user; processing the at least one image to obtain at least one metric of the eye, wherein the obtained at least one metric comprises at least one of: a sagittal depth of the eye of the user for at least one semi-meridian radial distance outside the cornea, a diameter of the cornea of the eye, a position of a center of the pupil or first Purkinje image of the eye, a radius of curvature of the cornea, or a position of the lids of the eye, and an aperture height between the lids; and determining, based on the at least one metric, 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.
