The UNC invention provides a system that corrects dynamically for the focus of the real world surrounding a near-eye display of an augmented reality user, simultaneously with the internal display of augmented synthetic imagery, with an aim of completely replacing the user’s prescription eyeglasses. The ability to adjust focus for both real and virtual stimuli will be useful for a wide variety of users, but especially for users over 40 years of age who have limited accommodation range. The UNC solution employs a tunable-focus lens for dynamic prescription vision correction, and a varifocal internal display for setting the virtual imagery at appropriate spatially registered depths.
