2-sided Varilux® Designs: The 2 Vs 1 Analogy

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

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: 360 º optimized designs customized to significantly improve the performance

The computed surface is cut on the lens using patented surfacing technology- completing the Essilor Advanced Digital Surfacing (ADS) 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! …the result is a Varilux 360™ lens!

 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

The key ingredient of a good PAL: DESIGN

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

Varilux Physio® W avefront Advanced Vision Enhancement NEW

 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

Source point Spherical 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 Blurred image Spherical Wavefront When a spherical wavefront passes through a lens, the refracted wavefront is usually no longer spherical (even if it is a spherical lens !) The image of a point is no longer a point, the wavefront is aberrated.

Defocus (Power) Astigmatism (Cyl) No aberration Coma Aberrations - impact on visual perception

TILT DEFOCUS ASTIGMATISM WAVEFRONT PRISM POWER CYLINDER PRESCRIPTION  The prescription of the wearer is removed to get the resultant Wavefront.

 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.
