Systems and methods for assessing vision and correcting vision problems are provided. A head-mountable virtual reality display controlled via a computing device can be worn by a user to display virtual reality images to the user. The images can be displayed as part of an interactive and engaging activity that can be used to determine a value of a certain parameter of the users eyes. The activity can also be intended as a treatment procedure during which users eyes are trained to perceive objects having certain properties that unassisted eyes of the user are normally not able to perceive. User input is acquired to determine users perception of the displayed virtual reality images. The computing device can be a smartphone configured to perform the vision tests or treatment under control of a remote computing device operated by a trained clinician.
