2-sided Varilux® Designs: The 2 Vs 1 Analogy
Classical Calculation Process From a Semi Finished lens, the “simple” back surface is calculated (simple means a sphere or a tore) to meet prescription requirements Prescription Rx lens (SF lens with simple back side) Back radii of curvature calculation SF Lens
360° Calculation Process Initial lens optical design (SF lens with classical Rx) Prescription Optimized lens ( SF lenswith unique complex back surface) SF Lens Lens Optimization Target Lens optical design (virtual lens with reduced power error and astigmatism)

Back Surface: 360º Optimization 3 Patents Advanced Digital Surfacing Rx Design Calculation Patented Polishing
These components allows us to create a collection of 2-sided designs in which: • Front Surface: Proven advanced designs which drive the performance • Back Surface: 360º optimized designs customized to significantly improve the performance
Essilor Advanced Digital Surfacing – A precise point-by-point process The computed surface is cut on the lens using patented surfacing technology- completing the Essilor Advanced Digital Surfacing (ADS) process… …the result is a Varilux 360™ lens!
Benefits of 360º Optimization • Creation of an Ellite collection of PAL designs with precise customization to provide wearers with an Ultimate Visual Experience. • An Ultimate Visual Experience that is: • Most Natural since design of the lenses is according to Human Physiology • Optimal since frontal design is matched tocustomized back surface design • Widest since aberrations are significantly reduced (+30% wider) • Sharpest & more contrasting* with further enhancement on back surface
(I) Varilux Physio® High Resolution Vision with W.A.V.E. Technology™
Varilux Physio® HighResolution Vision NEW Wavefront Advanced Vision Enhancement made possible by W.A.V.E.Technology
Features: W.A.V.E Technology™ • What is W.A.V.E. Technology™? • Wavefront analysis in optics • Astronomy • Refractive surgery (Lasik) • Contact lenses
W.A.V.E. Technology™ => Technical Innovation Control of the whole light beam passing through the pupil surface Single ray tracing through the pupil centre
What is a wavefront ? Wavefront = • locus of points reached at the same time by light from a given source or • a virtual surface perpendicular to light rays Source point Spherical Wavefront
Blurred image Wavefront Deformation (Aberration) When a spherical wavefront passes through a lens, the refracted wavefront is usually no longer spherical (even if it is a spherical lens !) Source point Spherical Wavefront The image of a point is no longer a point, the wavefront is aberrated.
Aberrations -impact on visual perception No aberration Defocus (Power) Astigmatism (Cyl) Coma
TILT PRISM DEFOCUS POWER ASTIGMATISM CYLINDER WAVEFRONT PRESCRIPTION First Order • The prescription of the wearer is removed to get the resultant Wavefront.
Aberrations definition & breakdown • Aberrations can be defined as terms of a breakdown into Zernike polynomials (very commonly used in optics, and in Essilor) 1st 2nd 3rd 4th etc… Conventional Refraction tilt tilt => Impact Visual Acuity + + defocus astigmatism astigmatism Higher order aberrations vertical Coma horizontal Coma trefoil trefoil => Impact Image Quality Secondary astigmatism Secondary astigmatism spherical aberration tetrafoil tetrafoil
The wavefront entering the pupil of the eye is evaluated for each gaze position The prescription of the wearer is removed to get the resulting Wavefront. The resulting Wavefront should be as aberration-free as possible.
