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 SF Lens Back radii of curvature calculation lens with simple back side)

360° Calculation Process Prescription Initial lens optical design (SF lens with classical Rx) Optimized lens ( SF lens SF Lens Optimization Target Lens optical design (virtual lens with reduced power error and astigmatism) with unique complex back surface)

Classical Vs 360º Calculation Classical Narrow Fields of view Non symmetrical design 360° Large Fields of view Symmetrical design

Traditional vs 360º ADS Surfacing Essilor® 360º ADS Traditional surfacing Diamond Tool Milling Turning Rough toric-like surface Smooth complex surface § Precise Realization of the Asian specific Design onto the Back Surface of the lens

Back Surface: 360º Optimization 3 P ate Rx Design Calculation Advanced Digital Surfacing nts 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 to customized back surface design Widest since aberrations are significantly reduced (+30% wider) Sharpest & more contrasting* with further enhancement on back surface

2 Vs 1 Surface Designs

The key ingredient of a good PAL: DESIGN

(I) Varilux Physio® High Resolution Vision with W. A. V. E. Technology™

Varilux Physio® High Resolution Vision NEW Wavefront made possible by W. A. V. E. Technology Advanced Vision Enhancement

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 Single ray tracing through the pupil centre Control of the whole light beam passing through the pupil surface

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

What is an aberration?

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 !) Blurred image 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

First Order TILT PRISM DEFOCUS POWER ASTIGMATISM CYLINDER WAVEFRONT PRESCRIPTION § 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) Conventional Refraction 1 st tilt + 2 nd astigmatism => Impact Visual Acuity + defocus astigmatism Higher order aberrations 3 rd trefoil vertical Coma horizontal Coma trefoil => Impact Image Quality 4 th tetrafoil etc… Secondary astigmatism spherical aberration Secondary astigmatism tetrafoil

About W. A. V. E Technology § 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. Wavefront entering the pupil of the eye Wavefront breakdown Removed Prescription 12 - 34 - - = Resulting Wavefront

About W. A. V. E Technology Resulting Wavefront controlled with W. A. V. E Technology
