Dr. Dhavid Cooper, CEO and Co-Founder of AFEyewear.com has created PDCaptureSM, a pupil distance measuring tool. The tool uses facial-recognition software and complex mathematical algorithms to detect a two-dimensional object from a photo accurately and consistently. Pupil distance measurements are made in less than a second.
AFEyewear 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 from the convenience of your computer.
