High-Order Wavefront Aberration Regularized Deconvolution (HOWARD) is a complete closed loop system developed for simulating human visual function with the primary goal of enhancing graphic computer displays for users that have refractive errors (resulting in difficulty interacting with visual displays). Visual function is a primary requirement for a human being to engage in computer usage efficiently. There are situations in which common forms of vision correction, such as contact lenses or glasses are not sufficient to provide the necessary compensation for some users to interact with graphic displays. This paper presents a model for the visual function of an imaging system, the implementation of an artificial eye with high-order wavefront aberrations, as well as a method for providing compensation of the artificial eye through a graphic display.
