Introducing Varilux® Physio® extensee™ – A New Era in Progressive Lens Innovation
Essilor continues to lead the way in progressive lens design with the launch of Varilux Physio extensee™, the latest innovation in the successful Physio family. This new lens features groundbreaking Pupilizer™ technology, designed to enhance visual sharpness and contrast by accounting for how pupil size naturally varies with lighting conditions.
Why It Matters:
Our eyes rely on contrast and sharpness for clear vision—both of which are significantly influenced by pupil size. However, traditional progressive lenses are often based on a fixed pupil size assumption, ignoring the fact that pupil size changes with age, lighting, object distance, and object brightness. This leads to an increase in high-order aberrations (HOA), especially in low-light conditions, which negatively impact visual clarity and comfort.
Key Innovations:
-
Pupilizer™ Lens Technology: Adapts to real-time pupil size changes to deliver consistently sharp vision.
-
Dynamic Pupil Modeling: Developed using a comprehensive AI-driven model based on the four key factors influencing pupil size:
-
Age
-
Object distance
-
Object luminance
-
Size of the luminous object
-
-
Enhanced Contrast Sensitivity: By reducing HOAs and tailoring lens optics to dynamic pupil profiles, wearers enjoy improved contrast and reduced visual fatigue.
Real-World Impact:
-
Addresses common complaints from progressive lens users regarding poor vision in low light and difficulty reading fine print.
-
Meets the needs of the 39% of wearers seeking better vision comfort in all lighting conditions.
-
Provides better performance throughout the day across a variety of tasks and environments
