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

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 a UK production leader in extending

the frontiers of ophthalmic free-form applications.

This sixth edition represents many continuous improvements,

the addition of shape blends and some very significant and

expanded changes in prism applications for progressives

explained in the bespoke section.

Successful dispensing.

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 6 resin indices.• The best possible optics currently available by blending two HD surfaces.• Simpleunfussyitting-Rx,PDs& Heights.• Option of full individualisation and customisation(CompensatedRx) whenspeciied.• Wider vision in the reading area, typically a neglected part of the lens.

Simplyfollowyourregularmultifocalittingprocedures: 1. Measure mono PDs - both distance and reading. 2.Measureittingheighttopupilcentre.

OPTIONALYoumaywishtoforwardotherframeittingmeasurements: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.

Thisfrontsurfaceinnovationprovidesbeneitstowearersinboththedistanceand 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

PRESCRIBERS NOTE:

Digitor multifocallensesareasigniicantlydifferentdesignfromprevious 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 changedopticalarchitecturecomeswithwiderieldsof 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,thesedatacreateacompensatedRxforcentralaxisofview.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.

Available in many fixed tints, Transitions and Polarised options, SPORTPAL opens a

new field of opportunities for lifestyle dispensing.

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 through Digital Ray-Path technology. Oblique astigmatism

reduced.

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

counter staff, teachers and dispensing opticians: 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

Indoor users design.

Clear vision all distances.

Far wider near and intermediate

compared to general wear

progressives.

Specify as regular progressive e.g.

additions +1.00 to +3.50.

SpeciicINSETvaluescanbe

requested.

“UB”Minimum 18mm

PS. DISPENSING TIP

For Dispensing Opticians’ own use in practice

working with patients fit 2mm higher.

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

front surface Image progressive

finished with an inner surface HD

digital design finish.

Ideal for those traditional front

surface design progressive wearers.

Increasing fields of view in all

sections, especially laterally,

reduce unwanted astigmatism.

A best of “both lens worlds” option.

User Key Points

Widestcleardistance,unrestricted

peripheral.

Stabilised inter & near zones across

all adds.

Higher levels of vision clarity achieved

through HD finishing.



• Pantoscopictilt 12°

• BVD-Trialandactualdistances 14mm

• Frontwrapangle 5°

Otherwise average default figures in RED

will be used as standard.

Digital DesignHigh Definition lenses bringing unsurpassed vision to your patients

NORTOR - SV Digital Design

DESIGNCombining two modern technologies, computing power and free-form

manufacturing, has enabled the single most significant design change in

ophthalmic lenses for fifty years.

NORTOR - perfect power in every direction

PREScRIBINGIdeal for ALL single vision corrections but particularly beneficial for higher plus or

minus prescriptions, specially higher cylinders.

Base Curve

Specific base (front) curves can be specified to meet the needs of the lens curve

matching the curvature of the frame design, e.g. sunglass wraps. On many occasions

using today’s stock lenses results in a poor curve match to that of the spectacle frame

design.SpecifyingaparticularbasecurveisineastheNORTORdesignsoftware

corrects its optics accordingly. Compatible with any index ophthalmic material.

Clear vision in every direction, oblique astigmatism substantially reduced.

SPORTOR

Plus8basewrapprescriptionsunlenses.WerecommendglazingbyNorvillefora

superbbevelinish.Yourspeciicationofwrapangleand/orpantoscopictiltangle

will trigger the calculation of a compensated prescription, which will also result

in additional decentration or prism. Available in Polarised form, Transitions and

Conventional lenses mounted in high-curved frames have a mediocre optical

performance.ThesamehighdeinitionNortoropticsofthesinglevisiondigitalray

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

equation. Available in many fixed tints, Transitions and Polarised options SPORTOR-SV

opens a new field of opportunities for lifestyle dispensing.

Ordering SPORTOR-SV HD :

• Patient’s full prescription

• Optical centres & heights, as required

• Lens base curve

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

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 mobile phones and other digital hand-held gadgets.

Nottobeoverlooked,every Booster design incorporates Digital HD lens design

for better all round sharper vision.

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 for the various distances required

for today’s electronic environment and constantly to remove their spectacles. The

Versatile degressive lens is a two-focus reading lens with a negative power

degression, giving the wearer that versatility of vision that they used to enjoy.

Versatiledegressivesareproducedusingprogressiveproductiontechnology.Nottobeconfused with occupational progressive (a 3-focus lens) differentiated by featuring a

range of plus additions.

Versatile degressives have a lesser (minus) power in their upper portion. For those

spectacle wearers with failing accommodation for near 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 office and work use.

These lenses are suitable for all presbyopic patients: early presbyopes who do 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 reading 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 reading would be better with a -1.25

degression.TheuniqueNorvilleVersatileDegressiveSetallowseasyPxassessmentoftheir requirements without incurring any re-orders.

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 -125

to identify horizontal line and top/bottom (degressive power to bottom).

Material(*otherthancR39)indicatedby60=1.60index,67=1.67index,etc.NorvilleVersatile is available in nine degressive (minus) powers -0.50, -0.75, -1.25, -1.50,

-1.75,-2.00,-2.25and-2.50.NorvillecanproduceVersatileinanyindex,materialortint (see page 62).

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 subtle blend-off edge effect. In minus Rxs this physically removes the

outer edge curve then blend polishes over. This reducing curve concatenation effects a

useful thickness reduction whilst avoiding a visible rimmed lenticular bowl.

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

edge means that it becomes a thicker edge, which then enables a further reduction of

centre substance to again achieve that original edge substance as specified for glazing.

SET is generally based around a 50mm clear central zone, although this can be altered

both larger and smaller.

Whilstthemosteffectivewaytoreduceedgethickness(negativepowerlenses)is

always to specify the highest index, having done just that any further edge reduction

will only be achieved by smaller eye sizes or lesser decentration.

Resin Super Lenti - High Minus Solutions

By cutting and polishing lower minus curves, or a plano flattening curve, to around that of the vertical spectacle frame

aperture dimension, e.g. 32-35-40mm, the edge thickness (ET) considerably reduces to an average of 50% edge thickness

reduction. The visibility of the blend can be modified by specifying the flattening blend.

Lenses with spheres, cylinders (virtually no limits) and reading additions (ULTORs) can be achieved.

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 segment bifocal

design. But there the similarity to old style bifocals ceases! As with inner surface

progressive designs, that segment also incorporates any cylindrical element!

Whowouldhaveeverthoughtacylindricalpowerroundsegmentadditionwouldbe

possible? Traditionally, these would have been spherical additions with the cylinder

power on the opposite convex lens surface.

Also, 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.

Bespoke Free-form

ANEXcITINGNEWWORLD 2016UPDATEBespoke 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.

Norvillewillthenapplyanenhancedhighdeinitionvisionsolutiontoyourpreferredlenschoice(anychoice!)usingexactlythe

same high quality point focus digital calculations.

It’ssimple–ratherthanuseconventionalinsidesurfacelensinishingwithits19thcstandardsphericalortoriccurves,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 digital 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 of Rx catalogue 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.

be a by-product of XXL frame choice, i.e. the larger the lens blank effective diameter

INVISIBLEROUNDSEGS(IRS)This design gives many opportunities for bespoke lens supply.

Seg Size

HDRD can be created in any round segment diameter from 15mm to 40mm.

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

PILOTOR UP&DOWNSThe 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 regular bifocal lens blank of any available 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

variations in upper focusing distances!

PILOTOR DOUBLE PPLs

Double progressive designs, with both an up and down progressive surface.

This is achieved by inverting a front surface progressive semi-finished blank

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.

Whilstabi-prism(slab-off)generallyjustcorrectstheverticalimbalance,aprismcontrolledoutcomewillendeavourtoshowprescribedorzeroprismatN.V.P.position.

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.

ANDTHENEXTFRONTIERWILLBE...As the eye views through different areas of the cornea, due to natures imperfect lens

surface variable vision outcomes become apparent. Different areas of the cornea are

used for distance and reading vision and it is very likely that varying cylinder powers

and axis would be recorded at those differing principal points.

Higher order lens calculations to correct shifts in gaze direction and to factor

implications of Listing’s Law will result in changed refractive power and axis across

the lens surface.

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 optical centre of the lens design is matched to Px’s

pupil - viewing position. For HD single vision vertical centration should also be recorded. Take the time to face fit the frame

before noting fitting measurements. Truly the best vision you’ve ever dispensed!

Free-form progressives NV fittingAfter many years of fitting regular progressives with fixed insets it would appear specifiers have lost the habit of recording

Free-form is GREEN

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

considerable greening of Rx lens production processes.

• Smallerlenses=lesswaste&lessmaterial

• Reducedwaterusage

• Reducedelectricalusage.

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

• Lesshazardousmaterials

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

that plastic powder 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 a 50mm eye size

produces and a 46mm even more from a small 55mm blank.

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 only one

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

The modern miracle of free-form production coupled with high index materials with the magic of slim edge thinning (SET)

software results in ophthalmic lenses of unbelievable appearance.

As long as we have all the key information elements Rx + decentration + eye shape we can make anything! Test us today!

Prescribed Power v Compensated Power

Prescribed Power

Prescribed Power is the given prescription. Conventional

lenses are calculated to yield this power when being

measured on a lensometer. However, when the wearer

is looking through different points of the lens oblique

aberrations appear, reducing the wearer’s visual acuity.

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.

Based on three key frame fitting measurements -

pantoscopic tilt angle,

frame wrap angle and

back vertex distances

distance between curves and back surface of the lens.

Prescribed Power

Traditionally straightforward

Powers easy to measure and compare to prescription

Variable Inset: Automatic and manual

Freedom in base curve selection

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 the “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

example, 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. Remember this is just a recalculation of the lens power which will give the correct outcome

±5.000DS held vertically in a trial frame close to the eye. without doing this then the lens power would be incorrect!
