addition lens (PAL) designs are so superior to traditional bifocals that nearly
all eyecare professionals who are presbyopic wear them. Yet, according to one study,
26% of all lenses dispensed in 2003 were bifocals or trifocals, while only 23.7%
of lenses were progressives. Why the disparity between what the eyecare professional
knows is best for the patient and what patients actually purchase? Individualization
and personalization of lenses is key to making patients want to purchase the best
lenses for them.
The VisionPrint System measures individual
head and eye movements.

experience unsatisfactory vision with traditional PALS, but Varilux Ipseo from
Essilor solves the main adaptation problem that patients typically experience. It
doesn't make sense to order the same design for every patient regardless of how
they use their eyes. Some complain that turning their head causes dizziness from
the "swim" in lenses; others say the area to read with is too small.
researchers solved this problem by asking the question, "What if we could measure
how much an individual moves their eyes and how much they move their head when viewing
objects?" They devised a method to customize the lens to the particular viewing habits of each patient. The
Vision Print System was born.
Quantify the essentials
System (VPS) from Essilor measures how much the patient moves their head and eyes
when viewing objects. It also measures how consistent they are. The VPS provides
stimuli in a random pattern, and frames connected to the VPS send signals to the
base unit relaying head and eye positions. The VPS technology provides a head and
eye ratio readout, which quantifies how much head and eye movement is used. A second
readout gives the stability coefficient that quantifies how consistent the patient
is in using those same movements.
these readings and the prescription are used to create a completely customized Varilux
Ipseo lens that corresponds to the patient's viewing habits. The eye mover gets up to a 60% larger viewing
area. The head mover gets up to 30% softer change in the periphery.
Pleasing the presbyopes
Varilux Ipseo for the past few months with remarkable results. Our technician uses
the VPS technology on every presbyopic patient. Once patients hear the story and
understand the concept, they want to be measured. Our patients like the Varilux
Ipseo for the thin appearance, non-glare features and the fact that they're easy
to keep clean.
fact, one of our more critical patients just received Varilux Ipseo lenses. This
68-year-old gentleman stood up, assumed a position like a tackle playing football,
turned his head left and right and screamed "Wow, I love these glasses, they are
the best I've ever had. They are great! They are perfect!"
Benefits all around
Varilux Ipseo and
the VisionPrint System from Essilor allow us to improve the quality of life for
our presbyopes. Converting just one bifocal lens wearer a day to an Ipseo lens will
increase gross income by $124,400 in a year and generate referrals from enthusiastic
the VPS allows us to maintain a high-tech image as well as generate enthusiasm among
the patients, staff and doctors. It also distinguishes us from other
