What’s Varilux® Ipseo®?
Ipseo®- A Latin word meaning “my own way”
Varilux® Ipseo® is the world's first progressive addition lens (PAL) to
integrate a specific individual’s physiological measures of eye and head
movement (in addition to their prescription’s parameters) into the lens
design for a totally custom-made PAL. Varilux® Ipseo® is a unique,
custom-made lens design for every presbyope based on the patient’s
prescription and their unique visual strategy.

How does it work?
Extensive research has shown that eye and head movements are
unique to each individual. Based on these new data points -the head/eye
stability coefficients- the Varilux® Ipseo® progressive lens surface
design is personalized by free form lens cutting software to fabricate a
distinct lens, custom-made to the individual's prescription and their
unique visual dynamics.
Your head/eye movement is measured using the Varilux® VisionPrint System™
to determine his/her unique “visual fingerprint.”
Along with the prescription and other measurements, two parameters (the
head/eye ratio and the stability coefficient) are taken into account to
design and create a unique progressive lens that responds to your unique
visual needs.

What is the Vision Print System (VPS)?
Essilor’s Vision Print System (VPS) a FDA cleared diagnostic
device, measures unique visual behavior of head and eye movements, and
allows for lenses to be individually designed to optimize a patients’
field of vision. The result is truly personalized, tailor made lens
perfectly in line with the wearer’s physiological and visual needs.

Why are head/eye movements so important?
The swim effect of progressive lenses is mainly due to head
movements, while, at the other end of the spectrum, the more a wearer
moves his eyes, the greater the lens area the eyes explore. So in order
to optimize a progressive lens, it is essential to know the patients
unique vision strategy.
All Varilux® lenses are based on the wearer’s physiological needs.
The designs of the first five generations of Varilux® lenses have been
constantly improved based on the common fundamental needs of large
populations of presbyopes.
Today, Varilux® Ipseo® lenses consider the individual physiological
differences of each and every lens wearer.
Advanced research demonstrates that eye and head movement ratio have a
direct correlation with the way the surface of the lens is used and how
objects are perceived :
Eye movements have a direct
influence on perception of fields vision. |
Head movements have a direct
influence on perception of swim effect. |
With eye-movers, the eyes scans a large
surface of the lens to explore the surroundings.
The more eye movement, the more critical it becomes to maximize the
width of vision fields for optimum comfort in dynamic vision.
With head-movers, the eyes use only the central portion of the lens for
foveal vision.
The more head movement, the more critical it becomes to minimize minor
distortions for optimum comfort in dynamic vision. The design must be
very soft in periphery to minimize the 'swim' effect.

Why is Varilux® Ipseo® considered a revolutionary solution?
Varilux® Ipseo®’s main technological breakthrough means that each
and every wearer can benefit from a unique optical solution, designed
from his/her unique physiological needs and as a function of his/her
unique natural visual behavior.
Compensation for all kinds of wearer conditions requires more than minor
adjustments, and it’s more than choosing from a variety of designs.
Every Varilux® Ipseo® lens is created from the individual wearer’s “visual
fingerprint.”
Each Varilux® Ipseo® lens is individually conceived and manufactured by
using state-of-the-art freeform technology. Freeform is the only
technology that allows the manufacturing of unique lenses without the
constraint of having pre-manufacturing molds, and also pre-defined
designs. Essilor patents in this field (designs creation, freeform, and
control) make it possible to create a very accurate personalization for
each wearer.
Freeform technology generates a complex design directly from a “hockey
puck” without using traditional tools and pads. Customization is a
design optimization which, by adding parameters to the current Rx,
allows lenses to be tailor-made to specific patient needs.
“Customized
Design” PALs fall into 1 of 3 categories: |
Customized to the Frame |
Customized to Lifestyle
|
Customized to Advanced
Ergonomics (Varilux® Ipseo®) |

Who can benefit from the Varilux® Ipseo® lens?
EVERYONE! However, this high-end offer is particularly recommended
for presbyopes who want to be sure that they are wearing the best
progressive lens – in terms of optical performance, comfort and
aesthetics – as well as know that they are getting the best service.
So Varilux® Ipseo® lenses are ideal for presbyopes who want a customized,
custom made solution.

Compared with other progressive lenses, what are the advantages?
Varilux® Ipseo® lenses are developed for the best visual
performance. They optimize visual field perception and foveal vision as
well as visual comfort as a function of a wearer’s visual behavior,
because everyone’s visual behavior is unique.
Varilux® Ipseo® is the only progressive lens that adapts to the wearer,
not the wearer to the lens.

-
What are the benefits compared to other Varilux® designs?
Varilux® Ipseo® creates a unique, custom-made lens design for every
presbyope based on patient’s Rx unique visual strategy.
Varilux® Comfort and Varilux® Panamic are multi-design progressive lenses.
For instance, Varilux® Panamic has 72 designs to accommodate for the
vision changes as the prescription changes.
Varilux® Ipseo® provides customization far-beyond optics … and each
Varilux® Ipseo® is engraved with the patient’s initials!

Are my Varilux® Ipseo® lenses engraved with the patient’s initials?
As mentioned above, Varilux® Ipseo® provides customization far-beyond optics … and yes, each
Varilux® Ipseo® is engraved with the patient’s initials!

-
Why is the Varilux® Ipseo® lens design so outstanding?
The head/eye ratio is used to optimize the fields of vision and minimize the swim effect. This ratio influences two important surface design factors:
A large foveal acuity zone for eye movements.
A very smooth peripheral variation to improve dynamic vision and retain natural head movements. Every lens is calculated and designed to correspond exactly and precisely with the head/eye movement ratio measured and yielded from the individual coefficient.
