1. A method of generating a manufacturing instruction file for the manufacture of a specialty contact lens, the method comprising:
acquiring three-dimensional points representing a surface of an eye;
automatically assigning two or more labels to at least some of the acquired three-dimensional points, the two or more labels representing scleral pathologies;
assigning geometrical distance constraints between at least some of the acquired three-dimensional points and at least one surface of the specialty contact lens, the geometrical distance constraints dependent on the assigned labels; and
automatically generating a three-dimensional numerical representation of at least one surface of the specialty contact lens, wherein at least some of the acquired three-dimensional points in the three-dimensional numerical representation of the at least one surface of the specialty contact lens conform to the geometrical distance constraints applied between the at least some of the acquired three-dimensional points and at least some points on the at least one surface of the specialty contact lens; and
acquiring an image of the surface of the eye and applying the geometrical distance constraints based on an analysis of the acquired image.
