Freeform Lens Design
Technology
What is a freeform lens?
A freeform lens normally has a spherical front surface and
a complex, three-dimensional back surface which incorporates the patient’s prescription. In the case of a freeform
progressive lens, the back surface geometry includes the
progressive design.
The freeform process utilises semi-finished spherical lenses
which are readily available in a wide range of base curves
and indices. These lenses are accurately machined on the
back side using state-of-the-art generating and polishing
equipment to create the exact prescription surface.
• the front surface is a simple spherical surface
• the back surface is a complex three-dimensional surface

Freeform Lens Design
Characteristics
Satisloh & Crossbows’ Custom progressive designs are
characterised by their large clear distance, intermediate
and reading areas and low rates of change of astigmatism.
This provides the patient with excellent clear vision under
all viewing conditions.
The soft designs provide the patient with excellent comfort
and easy adaptation for all corridor lengths and material
types. This ensures high levels of customer satisfaction
and exceptionally low non-tolerance levels.
The corridor lengths are all measured from the fit point to
100% of addition power, ensuring that even at the minimum fitting height, the patient has a useable reading area.
The range of fitting heights and designs allow the patient
the choice of a wide variety of frame shapes and sizes.

Freeform Lens Design
Software
The Custom freeform software was created to enable production of finished progressive lenses from semi-finished
spheres where the progressive design is machined on the
concave side and incorporates the patient’s prescription.
The software can be used in conjunction with Satisloh’s
freeform CNC machinery and lab management system to
provide the finished lenses for the laboratory’s customers.
Software integration is a simple process with the assistance of the experienced team of Satisloh and Crossbows.
The software has been designed from its inception to be
both flexible and easy to use.
Software application and integration
The Custom freeform software can be integrated as a
stand-alone solution in virtually any lab software environment, however both companies have carried out extensive
work to ensure that the Crossbows freeform software and
the Satisloh lab management system are fully compatible.
• File outputs are compliant with the latest Vision Council
(VC) standards. The software has the ability to be integrated with VC compliant lab management systems.
• The lab management system (LMS) supplies the job
information to the Custom freeform software with a lens
design system (LDS) file.

• From these details the Custom freeform software calculates
the surface data for the progressive design incorporating
the patient’s prescription and the center and edge thicknesses.
• The surface data file (SDF) is sent to a storage area which
can be accessed by the generating and polishing machines.
• The location of this storage area and the prescription details
are sent to the lab management system in an LMS file.
• When requested, the lab management system sends the
data location and any other information required to the relevant machinery, which may include the blocker, generator,
polisher, laser engraver etc.
• Credit is managed on a pay per use basis. Each time the
freeform software is run the appropriate amount is deducted from the customers’ credit.
• The remaining credit is displayed on the program status bar.
A warning will appear on the screen when the design fee
credit reaches a pre-determined level to remind the user
to order.

• Wider viewing areas for hyperopes (plus prescriptions)
• Improved distance area for myopes (minus prescriptions)
• Improved image quality in principal viewing areas
Ophthalmic lenses have oblique power errors which are present when viewing away from the optical center of the lens.
EyeView technology uses specially developed software
which incorporates the results of raytracing over the entire
lens to correct for these errors. Back vertex distance and
pantoscopic tilt are used in these complex calculations.

Prescription
Compensation
Considers the “as worn” condition
Prescription Compensation is an extension of the EyeView
principals, were an individual’s back vertex distance, pantoscopic tilt and face bow are used to adjust the sphere, cylinder
and axis of the prescription to give the best as worn condition
possible. This involves using a complex model of how the eye
looks through the lens.

the normal design process and has allowed Custom V to be
designed from the outset with a very smooth mean power
profile, thus minimizing swim effects and providing excellent patient comfort and rapid adaptation.

The Designs
Custom Lifestyle
The Custom Lifestyle range covers progressive lenses
which have been designed with specific needs in mind.
They do not have the all-round capabilities of a normal
progressive lens, but do excel in carefully selected areas.
Whether you require a lens for playing music, computer
use, driving, cooking or reading, there is a Custom Lifestyle product for you.
In addition to normal progressive lens wearers,
there are also designs that are suitable for:
• alleviating eye strain associated with near and intermediate work for the non-presbyope
• controlling the advance of myopia in young people
20 | 21
Custom Office
•
•
•
•
•
A superior design of office progressive lens
Low distortion soft aspheric design
Individual designs for left and right eyes
Variable design decentration
Eight dynamic powers available
The Custom Office freeform lens is designed primarily for
use in an office-type environment, however it also functions
well for any task where intermediate and reading vision is
of paramount importance. It is not a traditional progressive
design, but rather is an alternative to a reading lens, providing clear vision for reading and intermediate viewing. The
main differences between a reading progressive and office
design are as follows: a reading lens allows a presbyope
to have clear near vision, but renders anything beyond this
distance out of focus. A progressive lens allows clear distance and near vision connected by a corridor of intermediate vision. An office lens has a reduced width of distance
area and normally has a smaller change in power than a
conventional progressive which results in a much wider
central field and a reading area with very low distortion.
The wide range of dynamic powers allows the ideal choice
to be made for all reading additions up to 3.00 dpt and also
allows the user to benefit from fully corrected reading and
intermediate vision. The distance vision will be restricted
but will be more than adequate for use in an office environment. The design may help to reduce eye and neck strain
associated with long term use of computers.
Power Range
+6.00 dpt to -10.00 dpt, up to -4.00 dpt cylinder
(depending on range of semi-finished spheres)

Index
Notes:
• Dynamic power is the total reduction in power from
reading to distance area
• Lens is verified in reading reference circle only
• Dynamic power is selected from patient’s addition
• Lens is fitted using patient’s distance PD (pupillary
distance)

The Design
Custom Blended Bifocal
The Custom Blended Bifocal design is a bifocal but
without the obvious line around the reading segment.
The power changes from the distance prescription to the
reading prescription over a small region which makes the
bifocal segment almost invisible. This results in exceptionally wide and large distance and reading areas compared
to progressive lenses.

The Designs
Custom Single Vision
For the non-presbyope there is an excellent freeform
single vision range with sharp vision at all viewing angles.
This range is available in a wide selection of material types
and indices.
Custom Single Vision lenses minimise unwanted astigmatism associated with conventional single vision lenses.
Using EyeView technology combined with Prescription
Compensation results in a lens with superior optical performance, not only on the horizontal and vertical axes, but
over the entire lens surface.
There are also benefits to be gained both in terms of thickness and cosmetic appearance as flatter base curves can
be used without sacrificing optical performance.
26 | 27
Standard Single Vision
Custom Single Vision
This analysis shows the unwanted astigmatism of two different
single vision lenses, one spherical and one toric over a range of
gaze angles.
When the same analysis is done on Custom Single Vision
lenses, nearly all of the unwanted astigmatism that was in
the standard single vision lenses is no longer present. This
reduction in aberration is achieved not only on the horizontal and vertical axes but over the entire lens surface. The
differences are particularly marked towards the periphery
of the lens compared with the conventional single vision
lenses.
Once the eye moves away from the central viewing position
and looks obliquely through the lens, unwanted astigmatism is
present.
