MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202511059534 A) filed by Chandigarh University, Mohali, Punjab, on June 21, for 'non-invasive system for real-time pupillary distance measurement using image processing and ai on mobile devices.'
Inventor(s) include Mr. Sai Charan Labishetty; Ms. Tara Rani; and Ms. Apsara Shreshtha.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "The present invention discloses a non-invasive system for measuring pupillary distance (PD) in real time using artificial intelligence and image processing on mobile devices. The system 100 utilizes a front-facing camera to capture the user's facial image and detect ocular landmarks 101, including pupil centers, through AI-based algorithms. A reference object of known size is used for calibration 102 to ensure accurate scaling. The system computes 103 both monocular and binocular pupillary distances based on the spatial geometry of the identified landmarks. The invention further incorporates user guidance through visual and audio prompts, optional 3D depth estimation, and secure storage or transmission of the results. The solution eliminates the need for physical instruments or professional visits, providing a cost-effective, portable, and user-friendly alternative for optical profiling and virtual eyewear fitting, particularly suitable for remote or home-based usage."
