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.
If additional individualisation is
required please provide us with:
• 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

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

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.

• Patient’s full prescription
• Optical centres & heights, as required

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

• UsemonoPDsasifforPPL
• Advisepupilcentreposition(height)

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.
The optical surface produced, even at extreme powers, is an atoral design not just spherical/toric
i.e.HDopticalsurface.Noengravedmarkings.

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.
Norville’sHDbifocalscodedIRS(invisibleroundsegment)canbesuppliedinmostresin
lensmaterials.Wehaveselectedanumberofmaterialsnormally unavailable in the
bifocal lens form (see following pages). However, we can produce other combinations,
which you may wish to specify under the bespoke free-form option. IRS can be
supplied in any round segment size from 15mm to 40mm.
Bespoke range
All lens materials can be ordered as an IRS bifocal option.
Larger blank diameters than those listed “as standard” can be achieved by physically
decentring the seg position laterally at the time of production.

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.

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
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! But carrying the higher addition power split on the front segment and

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
(Image) and, as explained for the Pilotor, forming an inside free-form
progressive surface opposite to its usual distance position, remembering of

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.
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

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
near PDs. Please re-engage with reading PDs as HD progressives can be designed with variable inset measurements.

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.

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!
