Abstract
In an illustrative embodiment, an apparatus for imaging a portion of a mammalian eyelid has an eye contact lenspiece configured to direct the light through an eyelid from posterior to anterior surface to thereby trans-illuminate the eyelid, when the light source illuminates the contact lens. An imaging device receives an image of the eyelid as it is trans-illuminated. Other methods and apparatus are presented in various embodiments, hence this abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
