Digital curve calculation and free-form lens cutting

and polishing represent a REVOLUTION in ophthalmic

manufacturing. Digital is a giant step for ophthalmic lens

design; forward looking dispensers need to grasp these new

opportunities to avail their clients of their BEST VISION EVER

through High Definition ophthalmic lenses.

Digital free-form isn’t only about progressive lenses although

how brilliant it is to produce a lens surface that incorporates

cylinder and progressive surface blended together on the rear

of the lens, or even two different progressive designs,

their cylinders and additions (Auto-Pilotor). Example of the true

mastery of free-form technology.

Digital free-form is any optical surface that might benefit (all!)

from sophisticated computer wave-front modelling. Micro lens

surface calculation potentially changing the curve positioning

at 40,000 points across a 65mm lens; truly point-focal precision.

Norville is delighted to be UK production leader in extending

the frontiers of ophthalmic free-form applications.

This fifth edition represents those continuous upgrades, as

development is ongoing, and 2015 will surely bring further

new pages to the revolution!

Digitor lenses give wearers an outstanding visual experience, with spacious vision zones, improved peripheral vision, better looking lenses in many prescriptions and user-preferred near vision performance.

AN ADVANCED MULTIFOCAL LENS LIKE NO OTHER

is a truly elegant solution

FITTING DIGITOR

User Key Points• The very latest in multifocal ophthalmic lens technology.• Clear, Transitions and NuPolar options across 5 resin indices.• The best possible optics currently available by blending two HD surfaces.• Simpleunfussyfitting-Rx,PDs& Heights.• Option of full individualisation and customisation(CompensatedRx) whenspecified.• Wider vision in the reading area, typically a neglected part of the lens.

Simplyfollowyourregularmultifocalfittingprocedures: 1. Measure mono PDs - both distance and reading. 2.Measurefittingheighttopupilcentre.

OPTIONALYoumaywishtoforwardotherframefittingmeasurements:panto(tilt)angle, wrap angle and BVD. Particularly relevant when they are outside of the regular parameters e.g. wrap frames.

The Norville Digitor lens features a unique variable front surface base curve - a surface innovation that provides the optically ideal base curve across all viewing zones.

Depending on power, each lens comes from a different section of the “Elephant’s Trunk” curve, creating a unique variable front surface base curve that continually increases in dioptre from centre to edge.

Thisfrontsurfaceinnovationprovidesbenefitstowearersinboththedistanceand near zones. Wearers enjoy noticeably increased acuity in the periphery of the distance zone, as well as a reading area that is wider and more comfortable.

The HD inner calculation provides a more personalised outcome using average figuresortheonesyousupply.

PRESCRIPTION NOTE:Digitor multifocallensesareasignificantlydifferentdesignfromprevious progressive power lenses. Wearer experience has shown that for some in the middling and higher addition range changing over to a Digitor design may not be instantaneous, and perhaps requires a day or two for the wearer’s visual system to acclimatise. Digitor’s changedopticalarchitecturecomeswithwiderfieldsof intermediate and near and we would reassure users any slight delay in acclimatisation is worth the wait.

IDEAL for sports eyewear and sunglasses required with a reading addition.

The same high definition Ultor optics of the progressive digital focus design can be

calculated into a plus eight base wrap design. This can also incorporate (when

given) changes in back vertex distance, wrap angle (sometimes called dihedral angle

or face angle) and the tilt angle plane of the lens front from the natural vertical

viewing distance

Whencalculated,thisdatacreatesacompensatedRxforcentralaxisofview.The

compensated Rx equation affects the point of gaze and corrects off axis errors This,

combined with digital design, provides full width corrected vision across the lens

SPECIALIST Administrator Progressive

For those work station administrators, Bureau progressive lenses have some very

specific design factors Essentially close and near vision design for keyboard and

screen users but with the availability of an excellent intermediate with limited distance

field enabling fuller lens flexibility than just a simple office degressive two focus lens

design Smooth transition between zones

High definition achieved due to Digital Ray-Path technology Oblique astigmatism

reduced

Especially for older indoor professionals, executives, administrators, doctors, bank

counter staff and teachers, anyone whose work is predominantly near and close

vision, yet with the flexibility for attending meetings and presentations

*Bureau not recommended for driving.

- Administrator Progressive Characteristics

High placement of intermediate

gives 25% of total add power

at the pupil with a small but

respectable top area for far

vision, an easy to access near

vision area considerably wider

than a general wear progressive

Fit as a standard progressive

with fitting cross set at pupil

centre

User Key Points

ENHANCED Front Surface Progressive

An alternative progressive design philosophy that is both uncomplicated - yet very

visually effective Based on the proven IMAGE traditional front surface progressive

design with its comprehensive 15 option product range Rather than a traditional

spherical or toric inner lens surface finishing curves, a computer designed wavepath

tracked across both lens surfaces using 40,000 calculation points creates a beautifully

tuned free-form inner design for high visual performance SIMAGE HD software

cleans up those oblique aberrations enabling clearer vision over all zones Upgrade

clients’ vision to this optically supercharged solution with the optional choice of

calculationtopersonalisedwearingdatainput.Wherethisinformationisnot

presented, average default values will be used

Characteristics

A very modern combination of

path design can be calculated into a plus eight base wrap design This can also

incorporate (if available) changes in back vertex distance, wrap angle (sometimes

called dihedral angle or face angle) and the pantoscopic (tilt) angle plane of the lens

front from the natural vertical This creates a compensated Rx at the central axis of

view

This all affects the point of gaze and reduces unwanted Rx, axis or prism into the

BoosterNewGenerationdigitaldesignsinglevisionlensforpre-presbyopiapatients

25 to 40 years

Those working for long periods at close fixed distances are only too aware that visual

fatigue can set in: common symptoms of eye pain,dryness, gritty red eyes It has

been shown that the provision of a small plus area in the lower lens field can alleviate

this.NorvillehastermeditslensBooster Applicable to any lens material although we

highly recommend this with Vista-Mesh, offering office workstation users even further

user advantages

Booster power portion is available in two additive powers, +037 (“A”) or +062 (“B”),

depending on the accommodative needs of your patients

Ideal for avid users of digital hand-held gadgets

Nottobeoverlooked,every Booster design incorporates Digital HD lens design

for better vision across the centre of the lens

Digital Inner Surface Pre-presbyopia

Lens Marking

Booster lenses are marked with two

inward facing arrow heads

representing the horizontal reference

line The material index is marked

under the nasal arrow head, and

the additive power, A or B, under the

temporal arrow head

Booster is set as for any other SV lens,

however glazing technicians need to

remember that the lens must be located

with its Booster element at its lower

portion

Fitting:

• Orderasifforstandarddistance

Using an old fashioned one-focus reading lens has the inconvenience of not providing intermediate vision, causing the wearer to adjust their posture to adapt for the various distances required for today’s environment and constantly to remove their spectacles The Versatile degressive lens is a two-focus reading lens for the 21st century, giving the wearer that versatility of vision that they used to enjoy It is produced using progressiveproductiontechnology.Nottobeconfusedwithoccupationalprogressive(a 3-focus lens) differentiated by having a range of plus additions

Versatile degressives have a lesser (minus) power portion in their upper portion For those spectacle wearers with failing accommodation for near distances then degressives are the complete answer For intermediate and near, not just for computer users, but all those troubled by ageing vision; particularly useful for trades persons (e g painters, electricians) needing to achieve closer work distances, health professionals etc This is an all round lens for home use These lenses are suitable for all presbyopic patients The early presbyope does not like their distance vision being blurred and those older presbyopes who have lost their accommodation

This lens can be regarded as either a static or dynamic lens The static is for users that just require inter and near For example, high amount of computer use For these people use the lower degressions, e g a +1 75 add use -0 75 degression Dynamic is for people who have a more mobile requirement, such as a PA, librarian or someone working on a till For these people a +1 75 add would be better with a -1 25 degression.TheuniqueNorvilleVersatileDegressiveSetallowseasyPxassessmentoftheir requirements

Thousands of potential users haven’t yet been introduced to this immensely useful lens form by their Optician As an example, Transitions Versatile degressives are just great for site surveyors and others on outdoor construction projects Potential uses are extensive, from deep mines to deep space, wherever ageing human eyes need to respond to close detail The various Versatile designs are formed by digital design and free-form lens production (excepting clear CR39 version)

Versatile lenses improve the posture of bifocal or progressive lens wearers constantly dealing with computer terminals, reducing neck or shoulder pain

Free-form Versatile lenses have the following identifying markings: 60 -125to identify horizontal line and top/bottom (degressive power to bottom) Material (*other than CR39) indicated by 60 = 1 60 index, 67 = 1 67 index, etc (see page 63).NorvilleVersatileisavailableineightdegressive(minus)powers-0.50,-0.75,-1.25,-1.50,-1.75,-2.00,and-2.25.NorvillecanproduceVersatileinanyindex,material or tint

This lens product is hugely beneficial to both practice and patient Versatile is available in most lens materials in the ophthalmic lens price list but where not as standard can be individually specified as bespoke dispensing

Reduced Edge Blend - Minus & Plus Rxs Newfree-formlensprocessingtechnologyenablesthereductionoflensedgesubstance

by creating a blended edge effect In minus Rxs this physically removes the outer edge

curve then blend polishes back to approx 50mm of its original central “bowl” This

reducing curve concatenation effects a remarkable thickness reduction in both minus

and plus Rxs

Particularly clever with plus lenses, where creating a steeper minus curve just at the

edge means that it becomes much thicker This enables a further reduction of centre

substance to then achieve that original edge substance as specified for glazing, again

based around a 50mm clear central zone

Ironically, in the style of those old glass solid bifocals (segments on the concave

inside surface), free-form manufacturing allows us to produce a round blended edge

segment bifocal design But there the similarity to old style bifocals ceases! Because,

similar to inner surface progressive designs, the IRS segment also incorporates any

cylindricalelement!Whowouldhaveeverthoughtacylindricalpowerroundsegment

addition would be possible? As traditionally, these would have been spherical

additions with the cylinder power on the opposite lens surface The downside is a

slightly wider ring of blend area surrounds each segment rather than a thin visible line

(average2mmwidth).Whenfittingtakethisintoaccountbydropping1to1.5mm

lower

Remember, because blended designs are free-form they will have the added

advantage of atoral curve correction for HD vision right across the full lens

beyond the segment limits both for the distance and outer segment areas.

Bespoke Free-form

ANEXcITINGNEWWORLD 2015UPDATEBespoke Free-form

There may be many occasions when you desire to “supercharge” your client’s vision yet the lenses you wish to use are not

shownwithinourregularlistingasdigitalHDdesignoptions.Noproblem–youcanspecifyaBespoke Free-form solution

Norvillewillthenapplyanenhancedhighdefinitionvisionsolutiontoyourpreferredlenschoice(anychoice!)usingexactlythe

same high quality point focus digital calculations

It’ssimple–ratherthanuseconventionalinsidesurfacelensfinishingwithits19thcstandardsphericalortoriccurves,wewill

upgrade the design using an Atoral digital curve designed, calculated and produced with free-form lens surfacing technology

for point focal accuracy across its entire lens surface

This HD technology can be applied to any existing lens type or material, so upgrading the quality of its optics Just add the words

“HDdigitalfree-form”–HDtothelensform,e.g.S728Trifocal,HD free-form and we will do the rest

This is especially advantageous on large lenses, spherical powers over 3D, cylinders over 1D and lenses with prisms

Placing a progressive surface or an invisible round segment onto an existing traditional bifocal or trifocal front surface semi-

finished can dramatically change the visual scope of a lens, especially when any added round segment can vary from 15mm to

40mm in diameter Many exciting opportunities can be created that will enable the otherwise impossible Bespoke free-form is

opening up literally thousands of dispensing opportunities that previously didn’t exist

A very popular option we predict will be “double seging” To obtain that out of range addition add an invisible round segment

to the inside surface of an existing front surface segment semi-finished Enabling say a maximum availability of +3 50 add to

becomea+5.00addoption.Orperhapswhenneedingan80mmbifocalblank.Nowwecansay“simple”ratherthan“sorry

A number of proven options are listed on the following pages (see Bespoke page 113 of Rx price list for a costing guide)

Our free-form design team have come up with a solution for the patient who wants

their prescription to that large sunspec or frame no matter what

Effectively, we can produce XXL lenses up to 20mm larger than the regular stated

maximum lens blank diameter

However, one word of warning - the ED of the lens shape needs to be just less

than the maximum available blank size, i e lens blank diameter has to be at

least 2mm larger than the ED diameter of the frame we are glazing

Seg Size

IRScanbecreatedasaBLENDEDroundsegmentinanydiameterfrom15mmto45mm

Seg Position

Especially the smaller 15mm spot seg can be displaced latterly - vertically anywhere around the lens you specify Being an “invisible” design no-one is likely to notice its placement except the wearer!

“Double Deckers”

Placing one seg over the other (on different sides of the lens of course!) enables higher additions to be obtained As an example, one patient required +12 00DS with +5 00 add: the current Omega bifocal, available just to a +3 50 add was boosted by creating an additional +1 50 add on the inside surface thus reaching the +5 00 addition required

This technology is particularly advantageous with higher additions The reading fields of view in a +3 50 add conventional front surface progressive, whatever design, are fairly minimal

Putting a first time progressive wearer into a higher addition is unlikely to meet with visual acclaim!

PILOTORThe original Essilor design long discontinued, its revival now made possible through free-form technology In essence, a bifocal segment placed high up in the spectacle frame for intermediate use to read dials and gauges In an earlier age, this may well have been called “librarian lens”

Inverting a bifocal blank of the appropriate seg size (usually RD 40), we place an Ultor progressive surface onto its lower concave surface This would also be achievable with a trifocal lens blank for someone who needed

considerable variations in upper focusing distances!

UP&DOWNSDouble progressive designs, with both an up and down progressive surface This is achieved by inverting a front surface progressive semi finished blank (Image) and, as explained for the Pilotor, forming an inside free-form progressive surface opposite to its usual distance position, remembering of coursetoleaveasufficientwindowforadistancevisionportion.Yes,andwecouldproduceaTransitionsVIIorNuPolarvarietyofthesame!

The New World of Free-form HD Bi-Prism (Slab-Off)

As an aside we should today really not be encouraging the use of the words slab-off, deprecated by BSI, for Bi-Prism, which, of course, slab-offs are! However, now we can physically slab-on as well as slab-off prism perhaps this original term is still the more appropriate terminology!

The extraordinary outcome of free-form technology is how it has completely changed the technical aspects as to how we can now add prism, not just subtract prism So rather than coping with all the prism, say 3Δ in just one eye, we can now split the prism correction between both, i e 1½Δ B up and 1½Δ B down This has the advantage of more gently addressing the physical band of prism ridge-change That previous slab sharp line, sometimes as distinctive as an E style bifocal line, can now become an invisible blend line A further advantage where previously we needed to say to you 1½Δ was the minimum prism value achievable, now feel free if you desire to obtain ½Δ or ¼Δ bi-prisms! So with no restrictions on prism, lens type or materials - well, as far as we know - it’s down to you to prescribe comfortable vision, especially to those newly troubled by anisometropia, e g one eye cataract surgery

Our new free-form software and production process splits any correcting prism between both eyes i e base up / base down However, we can still supply the traditional approach with all the correcting prism worked base up in just the one eye only, but due to those higher prism values the interface blend line disruption is likely to be more noticeable (wider) by the Px

At the same time, this service also converts a previous basic spherical or toric optical surface to one of the new world of atoral corrected optics for HD all-round vision

Wewouldthereforeverymuchwelcomeuserfeedbackonanisometropiawearingexperiences with free-form bi-prism corrections, especially any Px who has previously worn a traditionally one lens slab off (bi-prism) sharp line corrective lens How do they get on wearing a dual or split prism option? There are also going to be issues with the blend line - where should it be placed vertically - which may be different for individual users, and there can be issues if the blend line is too wide

All the above are blend line bi-prisms either slab-ons or slab-offs It is possible to use the CR39 slab-on (base down prism reading), which is a sharp line design (think of E style) By using different prism values R&L eyes we can effect aprismcontrolled(vertically)outcomeattheNVP.Thisproductiscurrentlyonlyavailable in CR39, whilst all the previous blends can be achieved in any index

Free-form is GREEN

Norville is delighted to report that free-form lens production has enabled

considerable greening of Rx lens production processes.

• Smaller lenses = less waste & less material

• Reduced water usage

• Reduced electrical usage.

And most significantly, the move away from cadmium-based blocking metals.

• Less hazardous materials

There are always new areas for achievement and we are looking at ways (any!)

that plastic waste might be recyclable.

Small is Good, Small is Green

Over the last 50 years, with the advent of CR39 and resin lenses, we have

moved entirely to round lens blanks but very seldom do you actually have a

round eye frame to fit them into. Look how much waste even a 50mm eye size

produces and a 46mm!!

Nowadays we do have a range of stock lenses from 75mm round to 55mm

round but, with surfaced semi-finished, rather than keep so many diameters

in stock the manufacturers go for large only, so many lenses have no choice of

blank diameter.

Free-form enables Small

The free-form process is perfect for small lenses, for non round lenses even frame shaped lenses

In Rx lens surfacing, small means THIN

New technology brings with it new issues whose solutions have to be re-learnt. Digital design and free-form production are immensely complex. Fast Evolving Lens Technology (F.E.L.T.) is the apt description.

Nortor HD Fitting information All free-form digital designs are aspheric point focus so it is important the centre of the design is matched to Px’s pupil - viewing position Most prescribers are good at doing this for distance mono PDs but please re-engage with reading PDs as well as distance For HD single vision vertical centration should also be recorded Take the time to set frame up before noting fitting measurements Truly the best vision you’ve ever dispensed!

Prescribed Power

This is the entry level of technology that only considers a fixed, non-tilted lens i e power as given

This method is based on a pure geometrical conception of the lens: mixing curved surfaces, the lens will provide final wearers with the “given” power in a central gaze direction

As an outcome, the final lens is not optimised (compensated) Distance Power and Addition are unchanged as “given Rx”

Compensated Power

This is the newest technology in lens computation that includes any changes in Rx, caused by positional alterations resulting from the final fitting spectacles, by comparison with the trial frame or refractor head Rx

Compensated prescriptions for “as worn” positions

Due to the expansive capacity of modern computers, previous calculations considered too demanding can now be digested in seconds Previous to this, refraction Rxs were never corrected for as worn conditions other than assumed “allowances”

Today those fitting values can be accurately measured and input alongside Rx lens details into the computer lens design programme So those +5 00DS and -5 00DS lenses when corrected for actual tilt (panto) angle, wrap angle and BVD In this instance, using 12°, 12° and 12mm, we can note the compensated lens powers recalculated to those which will still result in the original prescribed Rx at the cornea
