Novar Technologies unveiled an innovative methodology that redefines optical lens performance evaluation, focusing on perceived power and astigmatism. This breakthrough, grounded in Generalized Ray Tracing (GRT) and virtual Shack-Hartmann wavefront analysis, marks a paradigm shift in lens design by prioritizing real-world user experiences.
Moving beyond conventional evaluation techniques reliant on theoretical and laboratory metrics, this approach integrates user-specific parameters—including lens curvature, pantoscopic tilt, wrap angles, vertex distance, refractive index and calculated eye rotation center—to deliver precise, user-centered visual solutions.
Key Innovations
- Generalized Ray Tracing (GRT):
Novar’s proprietary algorithm simulates light ray interactions with lens surfaces, offering a comprehensive analysis of refractive effects across a range of incidence angles. This advanced method accounts for real-world viewing scenarios, surpassing the limitations of traditional techniques. - Virtual Shack-Hartmann Wavefront Analysis:
Drawing inspiration from wavefront sensing technology, this approach evaluates perceived power and astigmatism across the lens surface by analyzing ray interception across fixed parallel planes. The result is high-resolution visual maps that mirror the wearer’s true optical experience. - Optimized Lens Design:
- Demonstrated reductions in aberrations for monofocal and progressive lenses.
- Enhanced vision quality through precise base curve selection, minimizing perceived power discrepancies and improving near and distance zones.
- Psycho-Optics Framework (Psicoptix ™):
Introducing a user-focused paradigm, this framework emphasizes the subjective optical experience of lens wearers, shifting the industry’s emphasis from theoretical metrics to practical, real-world outcomes. - Real-World Impact:
- For Professionals: Advanced tools to assess the implications of base curve selection and adjust designs for optimal user outcomes.
- For Patients: Tailored lenses that align with unique visual and lifestyle needs, delivering an unmatched viewing experience.
“By emphasizing perceived power and astigmatism, Novar Technologies has redefined the approach to lens evaluation and design,” says Gabriel Martin, Chief Technology and Innovation Officer at Novar Technologies. “This innovation empowers professionals to predict and address user needs, ensuring lenses provide an unparalleled visual experience in real-world settings.”
