title: The aniseikonic matrix.
abstract: The matrix optics formalism for astigmatic systems is applied to aniseikonia, and an aniseikonic matrix is defined. The aniseikonic matrix is particularly easy to compute even in the case of obliquely-crossed magnificant meridians between the right and left eyes. The straightforwardness of the matrix formalism as applied to aniseikonia provides a conceptually clearer means of understanding aniseikonic optics.
