(simple means a sphere or a tore) to meet prescription requirements

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

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 definition & breakdown
 Aberrations can be defined as terms of a breakdown into Zernike

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.
