An apparatus and system that uses lenses in front of a display screen to correct the vision of a user in near-eye display devices. The lenses replace the fixed lenses of typical near-eye display devices. The lenses have a wide range of adjustability such that users that require corrective eyeglass lenses or contacts can bring the displayed image into proper focus. This allows a user to experience near-eye display devices without the need for additional corrective lenses.
