THE 2010 PATIENT PROFILE
The 2010 Patient Profile
“In a strong sign that we are emerging from the global economic
crisis, consumer confidence is up sharply worldwide – including
Canada – according to the latest edition of the Nielsen Global
Consumer Confidence Index” from Consumer Confidence on
the Rebound: A Canadian Perspective (Nov 2009, Nielsen,
http://blog.nielsen.com/nielsenwire/consumer/canadianconsumer-confidence-rebounds/)
Eyewear and its sales are closely tied with consumer confidence
and in the light of the previous year and its effects on purchasing,

technology is applied to meeting every patient’s unique eyewear requirements. the Nielsen report shows a steady increase with the Canadian
index rising to 94, up 10 points since April.
In the Nielsen report, almost half the Canadians surveyed said
that local job prospects were good, 50% felt that personal
finances would be good or excellent and about 40% suggested it
was a good time to purchase the items that they needed.
Match Canadian census numbers (2006) with a changing
consumer confidence to see some product-matching
opportunities. The number of people aged 55 to 64; at 3.7
million is an opportunity for 3.7 million pair of progressives.The
65-and-over population, about 14% of the total population,
means opportunities for multifocals and progressive lenses that
add comfort (lightweight) and protection (UV and blue light
absorption). Increases in immigration since 2001 increases the
patient base and the number of people needing eyewear. So
promotion and targeted direct mail using supplier brochures and
cards announces new technology options.
Canada is still a young country with a median age of 39.5
years. That means that the SV lens opportunity is strong, half the
population is younger than the median. So, for something new
and exciting consider Essilor SV 360˚.
For patients of DEN, the 2010-eyewear opportunities are, great products, delivered with excellent service, that provide
outstanding patient value. It’s a mixture of material, design and treatment more than anytime in the past. Lens properties do not
exist by themselves but are combined by the professional optician to deliver a complete product with more comfort, protection
and the best vision to meet patient needs.
Excellent service remains a key practice differentiator. Be prepared to communicate the details and steps that go into
delivering terrific eyewear. That means everyone from reception through dispensing should add to the patient experience and
be confident making recommendations based on needs. Meet every patient expectation, be the best-educated possible anticipate
and uncover real needs as progressive-thinking professionals with the highest standards of education, technical skills, and
professional ethics, keeping patient welfare as their top priority. Members of Doctors Eyecare deliver comprehensive patientcentered eyecare integrated with high quality, high value vision products.

USE THESE RULES TO DETERMINE THE LOCATION OF POWER IN LENSES
1. At the axis, the lens only has sphere power.
2. 90 degrees (perpendicular) to the axis, the power is the sum of the sphere and cylinder values.
3. To solve for “90 degrees to the axis”; add 90 if the axis is less than or equal to 90, subtract 90 if the axis is more than 90.
4. Draw a lens cross showing the location of power and axes. Think of this as the eyewear in front of the patient’s face

Dissimilar Fitting Heights
Eyes are at usually different heights. For centering, this
should be taken into account as follows. In progressives,
order dissimilar fitting heights. This is especially important
for today’s shorter corridor lenses. For example, in a 14mm
minimum fitting height lens, the corridor is about 10mm
long. Therefore, a +2.00D add lens would be changing
about 0.2D per mm as the eye moves down the corridor.
In glasses where the fitting height is 2 mm different and
both eyes are fit to the lower height, the power of the lens

KEY STRATEGIES FOR SUCCESS
To make your practice the leading source
of fashion eyewear and sunwear in your
community, add…
World Class Brands: Prestigious brand names add
credibility. Become a “fashion eyewear destination.”
Fashion and Brand Insight: Be familiar with the latest
eyewear trends. Staying on top of the trends positions
you as the place to go.
Styling Savvy: There is no one frame choice that is
perfect for all patients. Identifying your patients’ fashion
preferences – and knowing the styles and collections that
best fit your patients’ tastes – helps you optimize their
eyewear selections.
Celebrity Status: A-list celebrities, sports figures and
everyday heroes continue to set the fashion pace. An
awareness of what frames the “Hollywood Hotties” are
wearing puts you and your associates in the fashion know.

yes – even here, in an optical office. A frame board, a table

Let your vendors become true partners in your business.
A savvy rep can help you tailor your inventory and ensure you
have a quick turnaround on reorders.
• Use hidden pockets of floor space – in reception, on counters, to display merchandise
• Bring the outdoors in with natural light, live plants
and fresh flowers
• Target customers with in-store visual
media, strategically placed flat screen monitors
• Add Wi-Fi, open networks that offer free access to
the Internet and create opportunities for social
networking, blogs
• Offer complimentary bottled water, coffee, a tray of
cookies, snacks
• Use sales associates as in-store models: real
people, in real life situations
• Use discrete signage for sale items; too much
discount chatter erodes the other visual messages
QUICK FIXES
Problem: Front window is cluttered, messy.
Solution: Rethink groupings and scale back on the
accessorizing. It may make more sense to let the eyewear and
the lighting do the talking.
Problem: No room to create unique displays.
Solution: Make sure the frameboard and/or any open shelves
are kept highly organized.
Problem: When the store gets busy, eyewear gets everywhere
except where it should be.
Solution: Use display trays and limit the number of styles
shown to any one customer at a time. The trays keep frames
organized and neat and give customers a physical boundary
within which to make selections.
Problem: Outdated POP materials.
Solution: Don’t give your customers a chance to ask for
a brand or a style you no longer carry. Edit your POP materials
as carefully as you edit your inventory. Vendors are more
than happy to send new signage.
How does your office look?

Taking the
best measurements
Since new lens design trends will require more personal
measurements, it places a new demand on the doctor and
optician. For example, lenses compensated for wrap sunwear
consider faceform (wrap angle) and base curve changes.
In Germany today, 60 percent of offices use sophisticated
digital camera type measuring systems, and 30 percent of
lenses are personalized.
Best service, new lenses and new technologies are reasons
for increased measuring precision. While new lens
technologies promise larger viewing zones that doesn’t mean
that fitting accuracy (PD, height, tilt, vertex) can be relaxed.
In fact, new technology suggests that we implement new
technically sophisticated measuring instruments. New lens designs perform better with accurate biometric
and personal measurements. That places a new demand on
the doctor and optician.
Consider purchasing a computerized digital camera
measuring system like Visioffice. It analyzes 3 dimensional
images of patients wearing their chosen frames. Attach a
reference device to the frame and measure exact monocular
and binocular PDs, fitting heights; pantoscopic tilt, vertex
What's Wrong With Dotting Height And Using A Pupillometer?
While this is successful for most progressives, about 10% of all lenses are redone. The majority due to errors are
for fitting height. This can be troublesome when you want every job to be perfect the first time.
Why are there errors? Employee turnover and the re-training required takes time and practice for excellence.
Here are the facts. PD’s by ruler can have errors of up to 4mm due to parallax errors, shaky hands or incorrect
procedures.
A pupillometer can have 1 to 2mm errors from posture, flipper or uncalibrated devices. Small errors can affect
satisfaction in high add lenses where an already narrow zone is made unusable by reducing the binocular field
of view.
Progressives require dissimilar lens fitting heights since virtually all patients have one eye higher than the other.
When heights are ordered the same, one lens will be too high or too low for comfortable reading. To deliver the
professional experience – offer more valueadded services and differentiation. Visioffice improves fitting accuracy
and enhances the purchasing experience.

Add the opportunity for frame try-on for final frame selection and it
helps the patient better decide their final choice. Scripts and interactive
lens demonstrations like designs, coatings, materials and sunwear lenses can
make the complex array of products simpler while demonstrating options
to the patient. Many offices that use these systems regularly increase
average sell prices since patients are more routinely exposed to more
benefits and eyewear possibilities.

AR LENSES ARE A MUST HAVE FOR
ALL PATIENTS
Simply put, no-glare lenses are essential for healthy vision.
They provide patients superior vision because, at the very
minimum, they reduce glare and improve the scratch resistance
of the lens. Premium no-glare lenses, like Crizal Forte, have
additional benefits such as exceptional scratch resistance, dust/
smudge repellence, and cleanability.
Consumers want and need no-glare lenses; in fact, 98% of
AR lens wearers will buy AR for their next pair of glasses
because of the visual comfort and aesthetics of the AR lens
look. Improved vision during night driving, reduced glare, and
improved overall vision add to the appeal. No-glare lenses
should be part of the conversation with patients and
incorporated into every vision solution.

THE PRIMARY OUTDOOR PAIR DELIVERS
100% PROTECTION AND PERFORMANCE
The best sunwear depends on a patient’s
lifestyle, the level of sun protection needed
and the visual performance required. To
best meet their needs, know wearers by
asking the right questions. For lifestyle,
define their outdoor activities, number of
hours spent outdoors and the primary
reason for wearing sunglasses. Then ask
how they usually protect their eyes from
the sun’s harmful rays, and how sensitive
they are outdoors to sunlight.
With those answers you can make a recommendation for
Everyday or Active Sunwear. In this way, the topics of contrast,
colour, comfort and protection can be best matched for their
need. Eyes protected with sunwear lenses provide optimal
protection. For example, Xperio polarizing lenses are ideal for
people that look for high performance and unparalleled
comfort. PhysioTints meet fashion color trends and reduce the
eyestrain that patients may experience with traditional
sunglasses.
Knowing the differences between sunlens materials, tints and
options allows patients to receive a level of customization
for sunwear that complements the way they live.

2. Airwear Sport – Designed for sports, these lightweight,
highly impact resistant, 100% UV and 90% blue light absorbing
lenses to reduce glare and improve colour perception. 6
Optimized Tints Filtering Harmful Blue Light were developed
with top athletes to deliver higher performance by sport or
activity. A mass tinted plano, 1,1mm thin, is molecularly
bonded to the front of a semi-finished lens blank. Once
surfaced, the lens delivers the best filtering quality in a tint that
won’t fade or change colour with subsequent coatings or AR.
Sports and the Presbyope –
Varilux Sport
For presbyopes, a general-purpose progressive limits distance
vision for the athlete since it balances the need for reading and
distance. Also, peripheral distortion creating swim is increased.
Single-vision works for dynamic vision requirements but
doesn’t address near and intermediate needs.
Varilux Sport is specially designed for the sport fanatics. Its
design increases distance vision and reduces swim so visual
performance during outdoor activities can be optimized.
Using digital surfacing, the prescription, add and distance
power are generated entirely on the back surface of a spherical
front surface lens to create Varilux Sport lenses. This design is
available in Airwear Sport tints, Essilor Grey and Brown Xperio
lenses and Airwear Melanin.
3. Melanin Lenses – Ultra-protection for customers who
place prime importance on their long-term visual health.
Melanin pigment is added to absorb blue light wavelengths,
believed to be a contributing factor to macular degeneration.
Melanin sunlenses are protective and reduce blue light that
adds to constant glare and blur.
4. PhysioTints - Developed to reduce chromatic distortion.
Developed with the photobiology laboratory of the Muséum
d’Histoire Naturelle de Paris, Essilor PhysioTints were
formulated to reduce chromatic adaptation resulting in
enhanced natural perception of colours and reduce eyestrain.
