With the Why limit the improvements of clarity and contrast, made performance of W.A.V.E. Technology in a lens specifically possible by digital surfacing to only progressive wearers? designed for small frames, eyecare professionals no longer have to Now provide the benefits of W.A.V.E. Technology to single compromise between their desire to provide the best in patient vision wearers. care and their patients desire for fashionably short frames. W.A.V.E. Technology is the source of the superior performance Standard short corridor lens 155° Sharper vision and improved perception of colours is possible when W.A.V.E. Technology is applied to single vision lenses. By analyzing wavefront distortions (propagation of light) Essilor SV 360° controls classic aberrations (power error and oblique astigmatism) and high order aberrations that influence image quality (sharpness, contrast, etc.). As a result the image formed on the retina is more accurate. Using 360° Digital Surfacing, the back lens surface is optimized, point-by-point to improve optical function for each prescription.The quality of vision depends on two key elements: visual acuity and contrast sensitivity. While visual acuity is essential, seeing the world as it really is depends largely on contrast sensitivity. Low light conditions or driving at night tax VARILUX Physio Short lens Some manufacturers shorten standard full-size designs to make short corridor lenses. The result is a shallow distance and a disproportionately large near. Varilux Physio Short is a unique new design tailored for the small-frame wearer. They enjoy the widest distance zone available in small frames (155°) — a proven satisfaction indicator for small-frame wearers. the visual system so lenses that can improve contrast sensitivity of Varilux Physio lenses. It enables Varilux Physio lenses to can improve vision is all situations. Consider Essilor SV 360° for provide sharper vision – up to 30% greater contrast sensitivity. the improved clarity and contrast.

Consider Essilor SV 360° or Varilux Physio f-360° designs, materials like 1.74 and the new sports or Crizal Forte treatments, all while teaching how 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.

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 scotch tape across the line. The tape should be completely in for the higher eye can be 0.4D less than the other eye.

In addition, the PRP will be located at dissimilar heights so take this into account when verifying prism. The same will be true with computer lenses. Therefore, order lenses with dissimilar heights. For visible multifocals and single vision. The OC height is typically delivered with equal heights and located at frame midline. For powers above 5 diopters on patients with >1.5mm difference in eye height, consider dissimilar OC heights to improve their vision and better equalize any prism posture changes as they age so take that into consideration. induced. Never assume that the previous height will be good for the new glasses. sponsored by Essilor Canada 11 NEW LENS DESIGN +3.00 sphere Plastic 1.50 Spherical design +3.00 sphere High Index 1.67 Aspheric design Lens design is constantly evolving.

So that’s what needs critical INCORRECT- slides down the nose PROBLEM- 90 degree bend, too far behind the crest of the ear attention. Be sure that the bridge fits the nose. Where bridges are flat, or there isn't a strong nose grasp the pad and pad arm with a plier and firmly angle it to match the nose. CORRECT- ~45 degree bend, avoids the mastoid bone, contoured behind the ear Adjust temple tilt so that the frame front is straight - to both you and the patient. Remember, patients may want the frames adjusted for uneven eye and eyebrow heights. Then make sure that the temple bends in a 45-degree angle at the crest at the top of the ear. Thinner frames are more easily adjusted than thicker ones. Some frames cannot be adjusted to fit a wide range of patients, so be sure that the frame fits correctly before the patient leaves and you’ve ordered the lenses. Some metals are rigid so fit is critical. A good fit on the bridge sits evenly with no gaps. The nose pad extensions sit at the same angle as the sides of the nose, and the patient feels comfortable. The frame sits straight and the asymmetry of eye and eyebrow height appears natural. The steps TO FITTING FRAMES ARE: 1 Nose - The bridge and any nose pads must follow the line of the nose smoothly without gaps or pressing on the nose; that would leave a red indentation. 2 Front - Straighten the frame, add the right pantoscopic tilt 3 Ears - Fit the top of the ears Using a narrow jaw nose pad plier, firmly rotate the pad to the angle needed. An angled snipe plier can get into the tight curve of a looped pad arm. It may be easier after removing the nose pad. sponsored by Essilor Canada 17 ONLY THE BEST FITTING FRAME Material Correct plastics Too Narrow Too Wide Say… Zyl Cellulose Acetate (zylonite or "zyl") • Keeps its polish and high luster • There’s almost endless color, pattern and texture possibilities • Laminates combine great colors and texture • Wonderful wide temples, shows off stones or brand logos Cellulose Propionate • One of the most comfortable and lightweight of materials • Stable in large sizes, even wraps • Less sensitive to warm weather • Holds its adjustment easily Grilamid • Highly durable and age resistant • Flexible even when thin • Hypoallergenic • Wide variety of color combinations Hytrel • Good in a wide range of temperatures • Maintains flexibility and lens retention Trogamid • For extreme conditions • Maintains good looks for the life of the eyewear Aluminum • Even thick parts are extremely light • Good variety of finishes • Hypoallergenic • Creates a “look Anodized Aluminum • Sleek and lightweight • Beautiful anodized finishes and colors Beta titanium • Light, comfortable, durable • Flexible and can be highly styled • Hypoallergenic Monel • Most popular metal frame material • Strong and easy to adjust • Get the perfect fit • Stable shape for a long time Stainless Steel • Bright shiny matte finish • Silver, black, copper, gold • Don’t lose their shape • Snug temple fit • Great for active wear “ Adjust the endpiece using a post and covered jaw plier FRAME MATERIALS glasses look.

Dol office style visual merchandising When it comes to visual merchandising, perception is key. Displays It is the way a store’s interior design or displays capture Ideas for displays can come from a range of sources, including someone’s attention and engage them. It’s how those visuals magazines, web sites and other retailers. Talk to your brand mingle with their memories, their self-awareness and their reps for display materials, point of purchase (POP) and desire to be a part of something. No one wants to spend time in an unimaginative, unclean or unorganized environment. Why? Your customers expect it at the big box department stores, the small neighborhood specialty shops, the grocery store, and yes – even here, in an optical office. A frame board, a table and a couple of chairs just won’t cut it in today’s competitive marketplace. The very same people who walk through your front door expect to find not just eyewear for sale, but an entire retail experience. So, take advantage of what brands like Varilux and Crizal have to offer. 22 TRY • Using props, like fresh flowers and signage • Letting spotlights create a focal point • Filtering in other accessory items (like handbags and neckties) • Making displays brand-specific • Integrating men’s, women’s, even children’s styles within a theme OFFICE STYLE: VISUAL MERCHANDISING any restrictions when advertising Hot Trends in Retailing brands. Keep a folder of ideas and a list of props and accessories to pick up. Also, change displays often. Recall cards, ad slicks for local newspapers and direct email to customers are great ways to complement POP strategies. But here, too, less is more. No one wants their mailbox or dispensing table flooded with brochures. Choose wisely – and always ask yourself, is this material and direct offer enhancing the image of my office? The answer, of course, should be yes. 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? sponsored by Essilor Canada 23 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. 24 TAKING THE BEST MEASUREMENTS More than ever, the sales process demands a wide range of expertise on your part • • • Assistance and advice on selecting a frame An increasing number of measurements requiring a high level of accuracy Information and sales argumentation on technological developments and the benefits and value-added features of the various lenses available distance and wrap angle; in one step.

Think of the immediate precision added to your office, staff measurement consistency and the improved information supplied to the lab. 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.

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. 7HATISGLARE UV – AN EVERYDAY DANGER • Year round sun protection is a must • 80% of UV rays penetrate clouds • In the city, UV is reflected by road, car, building and white wall surfaces • Outdoor workers are 5 to 10 times more exposed to UV than indoor workers • During summer, the UV Index is higher • In the mountains, UV increases by 10% every 1,000 meters proportionally • 60% of UV rays reach us between 10am and 2pm !WIDESELECTIONTOCHOOSEFROMNEWTINTSAVAILABLE 'LAREISTHEVISUALDISTURBANCECAUSEDBYTHERE¾ECTIONOFDAZZLINGLIGHT 0OLARIZATION ESSILOR SUNWEAR 0OLARIZATIONARISESISWHENTHESUN´SRAYSHITA¾ATSURFACEAROAD CARWINDSHIELDWATERSNOWSANDBRIGHTSURFACERE¾ECTASA Essilor POLARIZEDWAVEANDTHENVIBRATEHORIZONTALLYCREATINGDAZZLINGLIGHT sunwear solutions have been adapted to wearers needs by refining their performance with actual wearer feedback.

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.

Ocular globe - The Ametropia - Eyesight Emmetropia - Clear and Ophthalmologist – disorders that prevent a clear image from forming on the retina (myopia, hyperopia, astigmatism). Astigmatism - An irregularity in the curvature of the cornea, resulting in unequal blur in the two principle meridians. Bifocal lens - Lens with two points of focus, designed to relieve presbyopia. The lower part of the lens allows near vision; the rest of the lens is designed for far vision. comfortable eyesight in both far and near vision. Emmetropia is the opposite of ametropia. Fovea - Small depression in the central part of the macula located close to the optical axis of the eye. Glaucoma - Increase in intra-ocular pressure resulting, if left untreated, in an irreversible deterioration of the optical nerve and of the retina, as well as an alteration of the visual field, i.e. a reduction in visual performance, often accompanied by headaches and aching eyes. Cataract - Opacification of the crystalline lens. An extraction of the lens is usually replaced by an intra-ocular lens (implant).
