New Mexico Patent of the Month – June 2025
The newly granted U.S. Patent No. 12329514 marks a major advancement in eye tracking. The patent, titled Methods for dynamic position measurement of ocular structures using purkinje reflection spots, introduces a method to precisely monitor eye movements in real time. This innovation promises applications from enhanced vision diagnostics to next-gen AR interfaces.
Innovation at a Glance
WaveFront Dynamics Inc. has developed a system that uses Purkinje reflections-minute reflections from eye structures-to track dynamic eye motion. The invention pairs these reflections with advanced imaging and eye-position measurement tools in a unified setup.
How It Works
The system projects a structured light pattern onto the eye and captures multiple Purkinje reflection spots. These spots serve as reference points. By analyzing their movement, the device identifies instantaneous shifts in corneal, lens, or retinal positions. The method is fast, accurate, and non-invasive.
Real-World Impact
This technology could transform ophthalmology by enabling real-time monitoring of accommodation and early detection of cataracts. It may also streamline eye exams and improve outcomes in vision correction. Beyond healthcare, the method has potential in consumer tech, such as eye-controlled augmented-reality displays.
Why It Matters
By combining wavefront analysis with dynamic Purkinje spot tracking, the system achieves high precision and efficiency. It automates complex measurements and reduces dependence on technician alignment. This approach could lower costs and raise access to advanced vision diagnostics.
The patent reflects a leap forward in eye-tracking and eye health technology. Users can expect more responsive AR devices and better tools for early disease detection.
