External eye-contact device having opaque and decentered light-transmissive portions

A trial kit comprising a plurality of trial eye-contact devices each having different values relating to optical design parameters of the trial eye-contact devices such to allow a user of the trial kit to sequentially select at least two of the plurality of trial eye-contact devices for implementing an iterative optimization process in which values pertaining to the optical design parameters are convergent until a combination of device parameters is determined based on feedback for a given patient, each of said trial eye-contact devices comprising:

• a contact lens body having a rotational symmetry axis that virtually intersects a location on the retina lying within a radius of a non-dilated pupil, the contact lens body having a distal device surface and a proximal device surface, comprising:
• an opaque portion;
• and
• a light-transmissive portion consisting of a single pinhole that is operable to direct light from the distal device surface to the proximal device surface along an optical axis that is different from the symmetry axis of the contact lens body,
• wherein the optical axis of the single pinhole intersects a second location of the retina exceeding the radius of the non-dilated pupil,
• wherein when the contact lens body operably engages an eye having an optical axis, the rotational symmetry axis coincides with the optical axis of the eye, and
• further wherein the contact lens body comprising the light-transmissive portion is configured to direct light propagating through the light-transmissive portion such to be incident onto the second location that is within the eye's macula but not on the fovea located in the macula.
