MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202611040436 A) filed by Galgotias University on March 31, 2026, for A Digital Interpupillary Distance Measurement Device Using A Custom-Made Flexible Facial Scale.
Inventor includes Dr. Raj Kumar.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present invention relates to a non-invasive digital system and method for measuring interpupillary distance (IPD) using a custom- made flexible facial scale in combination with camera-based imaging. The flexible scale conforms to the patient’s facial anatomy and serves as a reference for accurate measurement. Digital images are captured while the patient fixates on a distant target, and the corneal reflex is used as an anatomical landmark to determine pupil positions. The system enables precise measurement of monocular and binocular IPD, reduces errors associated with conventional methods, and allows for digital storage and analysis of data. The invention provides a cost-effective, accurate, and user-friendly solution suitable for clinical, optical retail, and academic applications.
