FramesDirect.com is able to measure a patients' PD (Pupil Distance) instantaneously from a photograph. Using proprietary facial recognition and imaging technologies, the system automatically recognizes known objects and reflections from the cornea, called Purkinje images.
If no Purkinje image is available, the system is able to recognize the borders of the iris to accomplish the same stunning level of accuracy.
Pupil distance measurements are taken at the time of an eye examination. Occasionally the PD information is omitted on an eyeglass prescription.
Now, getting a PD measurement as accurate as the doctor's can be done by taking a head shot and sending along to our team of expert opticians.
