a light source to generate a light beam;
a camera; and
an optical component comprising:
a first optical zone characterized by a first sag profile to correct a refractive error of an eye of a user;
a second optical zone characterized by a second sag profile to redirect a path of the light beam from the light source to the eye of the user, wherein the light source is oriented with a view only through the second optical zone; and
