NEW ERA IN PROGRESSIVE TECHNOLOGY |
WHY
AN ADVANCED DESIGN IN PROGRESSIVE LENSES?
Even with the most skillfully refracted prescription, many
patients still complain of peripheral visual distortion or
a narrow field of vision when they first try their new progressive
lenses. Many patients fail to adapt to the lenses that could
make clear vision virtually effortless.
VARILUX® IPSEO™ – THE
FIRST TRULY INDIVIDUALIZED PROGRESSIVE LENSES
- Varilux Ipseo lenses have no preconceived design,
and utilize each patient’s unique measurements.
- The design of Varilux Ipseo lenses integrates the individual’s
unique physiological movements,
in addition to prescription power and frame measurements.
 RECORDING
EACH PATIENT’S UNIQUE VIEWING STRATEGY
- The Varilux® VisionPrint System™, an FDA-cleared
device, scans your actual head/eye (H/E) movements under
natural conditions.
- Based on your visual habits, H/E ratio is captured
by the VisionPrint System.
- A stability coefficient is also recorded to measure
the variation in the your head/eye
movement and ensure the accuracy of the reading.
Varilux Ipseo lenses recently received the eye care industry’s
Technology and Fashion Grand Prize: the SILMO Special Prize
at the 2004 SILMO trade show in Paris. From over 55 entries,
Varilux Ipseo was chosen as the most innovative lens in
the last 10 years. |
| A
NEW WAY TO MEASURE SUCCESS |
MEASURING
YOUR UNIQUE H/E RATIO
- Studies show that head/eye movement is a behavior
that is rooted in each patient, and is stable over time.1
- H/E ratios cover the complete range – from
patients who move only the head, to patients who use
a combination of head/eye movements, to those who move
only the eyes while viewing peripheral objects.
2
In other words, every wearer has a unique strategy for
viewing peripheral objects. More important, this strategy – which
has been “learned” from birth – is deeply
ingrained and is resistant to change.
AN ILLUSTRATION OF THE H/E RATIO
Consider the differences between illustrations below. In
each illustration, eye movements are illustrated by red
and green angles, and head movements are illustrated by
blue angles.2
|
HEAD
MOVEMENT
Patients who tend to keep their eyes fixed and turn
their heads are called Head Movers.3,4 The
more head movement, the more critical it becomes to
minimize peripheral distortions.
(left) The H/E Ratio is “1”, indicating
that the patient views peripheral objects by rotating
only the head. When reading a magazine, the patient’s
eyes remain relatively fixed while the head rotates
across the page. Accordingly, this patient uses
a relatively small portion of the progressive
surface. |
|
EYE MOVEMENT
Patients who tend to keep their eyes fixed and turn
their heads are called Head Movers.3,4 The
more head movement, the more critical it becomes
to minimize peripheral distortions.
(left) The H/E Ratio is “O”, indicating
that the patient views peripheral objects by rotating
only the eyes. While viewing peripheral objects
(such as the pages of a magazine), the patient’s
head continues to face straight ahead while the
eyes rotate across the page. Accordingly, the
patient uses a large portion of the progressive
surface. |
|
EQUAL
MOVEMENT
(left) The H/E Ratio is “0.5”, indicating
that the patient views peripheral objects by rotating
eyes and head equally. The patient with an H/E
Ratio of “0.5” will rotate the head
to the midpoint of each page, and use rotation
of the eyes to view the extreme edge of the page. |
Varilux Ipseo lenses are designed for the unique combination
of head/eye movement that makes up a patient’s individual
viewing strategy. Since no two patients view the world in
the same way, with the same head/eye ratio, no two
Varilux® Ipseo™ lenses are ever the same. |
