1. A method comprising:
capturing at least one image of an eye of a user with an image sensor while the eye is illuminated;
processing the at least one image to obtain a plurality of metrics of the eye of the user, wherein the obtained plurality of metrics comprises:
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, and
a position of the lids of the eye, and an aperture height between the lids; and
determining, based on the plurality of metrics, 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.
