OptoCalc verified calculation reference: Freeform programs can combine design optimization, position-of-wear inputs and supported surface features. Each feature must be selected for the actual design and order rather than assumed from the word “Freeform.”
ODP provides design optimization; 4K increases calculation resolution; OMD targets a lower and smoother unwanted-astigmatism distribution where supported.
Supported calculations can use IPD, fitting height, DBL, HBOX, VBOX, FED, pantoscopic angle, wrap angle and back vertex distance.
Allows controlled customization of far, intermediate and near field priorities or the combination of design characteristics.
Combines matched convex and concave Freeform surfaces for supported individualized progressive programs.
Final feature availability depends on the selected design, calculation license, prescription, frame data and production configuration.
Freeform describes a manufacturing and design approach
Digital surfacing can create complex lens surfaces from a selected design file. It does not by itself mean that every lens is fully personalized.
Customization depends on supplied data
The result can only use parameters supported by the chosen design program and supplied accurately with the order. Missing or incorrect frame and fitting data cannot be corrected by the surfacing process alone.
Performance is verified against the prescription order
Finished lenses should be checked for power, geometry, markings, appearance and mounting requirements using the agreed specification and applicable standards.
- Create the job reference: enter the customer reference, wearer or patient reference, urgency and any production message so the order remains traceable.
- Choose the finishing route: confirm fast uncut, uncut with precalculation, customer-supplied frame, remote edging or frame-and-lens package, plus the frame or mounting type.
- Enter frame geometry: upload a trace when available or supply the selected shape with HBOX/A, VBOX/B, DBL and other required geometry. Confirm drill, groove or shape-adjustment data when applicable.
- Enter the right and left RX: select the named freeform design and record SPH, CYL, AXIS, ADD, monocular far PD, fitting height/SEG and prescribed prism magnitude and base direction for each eye.
- Confirm the lens system: select material and refractive index, diameter, clear/photochromic/polarized option, coating, tint and any supported advanced parameters.
- Run technical review or precalculation: check blank diameter, base curve, minimum center/edge thickness, frame coverage, centration and production limits before release.
- Review and submit: verify the checkout summary against the original order, approve the job, then use the order-status record for tracking, queries, reorders or controlled remakes.
A freeform lens is produced with digitally controlled surfacing that can create complex optical surfaces from a selected design file and verified order data.
No. The degree of personalization depends on the selected design program, the parameters it supports and the accurate fitting and frame data supplied with the order.
They are removable external layout markings used to show fitting references, alignment points, eye side and design scale. They are different from permanent engraved identification marks.
No. A selected design can manage optical trade-offs and distribution of unwanted aberration, but it cannot eliminate every aberration for every prescription, frame and viewing direction.
Supported programs can include single vision, progressive, sunglass, photochromic, polarized and CR39 or selected high-index options after technical review.
Yes, where compatible. Hard coat, anti-reflective, hydrophobic and selected functional treatments must be matched to the substrate and complete product program.
No. Adaptation varies by wearer, prescription, design, previous lenses, frame fit and fitting accuracy. No design should guarantee instant or symptom-free adaptation.
Send the job reference, complete right/left SPH, CYL, AXIS and ADD, prism/base when prescribed, named design, material/index, diameter, monocular PD, fitting height/SEG, frame trace or HBOX/A, VBOX/B and DBL, treatment requirements, finishing route, quantity and destination market.
Custom Digital Freeform Prescription Lenses
Heritage Optical Lab supplies digitally surfaced freeform lenses for optical laboratories, retailers, distributors and private-label programs. Options can include single vision, progressive, sunglass, photochromic, polarized and CR39 designs.
Digital surface generation
A CNC freeform generator produces the selected complex surface from a controlled design file and verified job data. The finished surface is then polished, cleaned and inspected before further treatment or edging.
Design and personalization inputs
Supported inputs may include monocular PD, fitting height, frame measurements or trace and selected position-of-wear parameters. Availability depends on the design program and must be confirmed before production.
External layout markings
Blue removable external markings can identify fitting references, alignment points, eye side and design scale during laboratory verification and dispensing. Permanent engravings and removable layout marks serve different identification functions.
Optical verification
Freeform manufacturing does not eliminate all aberration or guarantee instant adaptation. Finished lenses are verified against the prescription order, selected design, fitting data and applicable optical and geometrical requirements.
OEM and wholesale supply
For sampling and quotation, provide the RX range, design, material/index, diameter, fitting and frame data, coatings or functional treatments, finishing method, quantity, packaging and destination market.
