MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202621091727 A) filed by Mr. Shubham Bhattacharya; Ms. Sushrita Mahadani; Dr. Meghana Patel; Ms. Mohamita Tripura; Ms. Rishika Singh; Ms. Pampa Bhowmick; and Ms. Dahlia Biswas on July 29, 2026, for A Portable Device And Method For Real-Time Assessment Of Color Vision Deficiency In Clinical And Point-Of-Care Settings.
Inventors include Mr. Shubham Bhattacharya; Ms. Sushrita Mahadani; Dr. Meghana Patel; Ms. Mohamita Tripura; Ms. Rishika Singh; Ms. Pampa Bhowmick; and Ms. Dahlia Biswas.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: The present invention relates to a portable electronic device and method for real-time assessment and classification of color vision deficiency (CVD). The device comprises a portable housing, a calibrated high-resolution display module, an embedded processing unit, memory, a user input interface, an ambient light sensing module, a rechargeable battery, communication interfaces, and internal calibration circuitry controlled by embedded firmware. The firmware generates standardized color vision stimuli, acquires patient responses, performs automated diagnostic analysis, classifies the type and severity of color vision deficiency, and generates diagnostic reports in real time. The device automatically compensates for ambient illumination, performs display calibration, and provides objective, repeatable, and examiner-independent assessment. Diagnostic results may be stored locally or transmitted to external devices, electronic medical record systems, or cloud platforms through wired or wireless communication interfaces. The invention enables rapid color vision screening, typically within 2 to 5 minutes, and is suitable for use in ophthalmology clinics, optometry practices, hospitals, educational institutions, occupational health programs, military recruitment, transportation licensing, industrial screening, telemedicine, and community healthcare applications. The modular architecture further supports future integration of artificial intelligence, eye-tracking technology, and additional ophthalmic diagnostic functions.
