1. A system comprising Simultaneous Split Point Focus (SSPF) and Low Latency Dynamic Distance Monitoring (LLDDM) for enabling self determination of eyeglass prescription for a user via a mobile computing device, the device comprising:
volatile and non volatile memory for storing data;
a processor configured for executing program instructions stored in the non volatile memory;
a visual display screen adapted to receive image information from the processor to present instructions and images to a user; and
a camera configured to receive images of the user's pupils during a test situation;
wherein the system comprises application program instructions for directing the processor to undertake a method for determining an eyeglass prescription, the method comprising:
determining if an eye of the user is myopic, and if the user's eye is myopic;
determining Principal and Axis Meridians of a user's eyes while the user is observing the image information on the display screen;
enabling the system of LLDDM for real time determination of the refractive power errors in the Principal and Axis Meridians of a user's eyes in while the user is observing the SSPF image information on the display screen;
calculating Sphere, Cylinder and Axis prescriptions from the Principal and Axis Meridian values obtained via the LLDDM system; and
displaying the calculated prescription values to the user.
