Who We Support
Prism Lenses Options for Different Customer Needs
Select the appropriate prism lenses design, material, treatment and finishing from the prescription, frame, intended use and destination-market requirements.
Ground-in prism combined with the ordered sphere and cylinder where manufacturable, after power, base, frame and thickness review.
Prism prescription paired with a compatible blue-filtering material or treatment after spectral, residual-color and coating review.
Branded photochromic-compatible prism program subject to prism, material, activated color, coating and market availability confirmation.
Higher-index prism construction reviewed for total RX, wedge thickness, diameter, frame shape, Abbe value and material availability.
Prism prescription combined with a compatible photochromic system and specified activated color, transmission and coating requirements.
Clear CR-39 prism option reviewed for prescription, diameter, wedge thickness, frame and coating requirements before production.
Complete Prism RX and Construction Review
Submit SPH, CYL, AXIS, ADD, prism amount and base direction or angle for each eye, including how horizontal and vertical components are allocated.
Material/index, Abbe value, blank diameter, frame trace, monocular PD, fitting height, decentration, minimum thickness and mounting method are reviewed together because prism creates an asymmetric thickness distribution.
Precision Ground-In Prism Surfacing
Ground-in prism is incorporated into the spectacle lens and may be combined with ordered sphere, cylinder and ADD powers where the construction is manufacturable.
Freeform or other supported surfacing methods can manage the specified power and prism construction, but they do not guarantee a fixed thickness reduction, symptom relief or adaptation period.
Prism Power and Base-Direction Verification
Finished lenses are checked for the ordered sphere/cylinder/add power, prism amount and base direction at the specified reference point, together with geometry, markings, appearance and treatments.
ISO 14889 states fundamental requirements for uncut finished spectacle lenses, while ISO 8980-1 specifies applicable optical and geometrical requirements and verification methods for uncut finished single-vision and multifocal lenses.

- Prism / Construction Review
- Prism Lens Facts
- Ordering Workflow
| Review item | Order data | Production impact |
|---|---|---|
| Complete prescription | SPH, CYL, AXIS, ADD, prism amount and base direction/angle for each eye | Defines the ordered optical powers and prism vector |
| Prism allocation | Right/left distribution, horizontal/vertical components and reference point | Prevents ambiguity when prism is split or specified obliquely |
| Material and blank | Material/index, Abbe value, diameter, base curve and availability | Affects wedge thickness, weight, chromatic dispersion and manufacturability |
| Frame and fitting | Frame trace, monocular PD, fitting height, decentration, wrap and mounting type | Affects usable blank size, thickness distribution, centration and glazing |
| Treatments and verification | Hard coat, AR, blue filtering, photochromic option and acceptance criteria | Confirms compatibility and the finished-lens inspection plan |
Prism amount and base direction are both essential
A prism prescription requires a magnitude in prism diopters and a base direction such as in, out, up or down, or an angular/vector specification. The laboratory must receive unambiguous data for each eye.
Ground-in prism shifts the image
A ground-in prism is incorporated into the spectacle lens. Prism may also be induced by decentration in suitable powered lenses, while temporary Fresnel prism is a separate removable product with visible segments.
Thickness and performance depend on the whole job
Prism creates an asymmetric thickness distribution. The final profile depends on total RX, prism allocation, base direction, material/index, blank diameter, frame shape, decentration and minimum thickness. Higher index can support a different construction but does not guarantee a fixed percentage reduction.
- Submit the complete RX: include SPH, CYL, AXIS, ADD, prism amount and base direction or angle for each eye.
- Confirm prism allocation: state whether horizontal and vertical prism is split between eyes or assigned to one lens.
- Provide frame and fitting data: include frame trace, monocular PD, fitting height, decentration and mounting method.
- Review construction: compare compatible materials/indexes, blank diameter, base curve and center/edge thickness targets.
- Specify functional treatments: confirm compatible hard coat, AR, blue filtering, photochromic option or tint.
- Approve feasibility and lead time: timing is confirmed only after the full RX, construction, coating, finishing and quantity review.
- Verify the finished lenses: check power, prism amount and base direction at the specified reference point, geometry, markings, appearance and treatments.
It is a spectacle lens with prescribed prism incorporated into the lens construction. Prism shifts the observed image and is specified by both magnitude and base direction. It is different from a removable segmented Fresnel prism.
A qualified eye-care professional must determine and issue the prism prescription. The laboratory manufactures the lens to the submitted order and does not diagnose binocular-vision conditions or select the clinical prescription.
Provide prism amount and base direction or angle for each eye, right/left allocation, any horizontal and vertical components, the reference point, and the complete SPH, CYL, AXIS and ADD powers where prescribed.
Yes, where the complete design and construction are manufacturable. The laboratory must review total RX, material, blank diameter, frame, fitting data and thickness requirements before confirming the job.
Orders may specify base in, out, up or down, or an oblique/vector direction. Supported combinations and power ranges are confirmed after the prescription and construction are reviewed; no universal maximum applies to every material and frame.
Prism creates an asymmetric wedge, so thickness depends on prism amount and direction, other lens powers, material/index, blank diameter, frame shape, decentration and minimum thickness. Higher index may help a given construction but does not guarantee a fixed percentage reduction.
Compatible treatments may be available after material, power range, color, transmission and coating-stack review. Branded photochromic availability must be confirmed for the chosen material and destination market.
Wearer adaptation varies and should be discussed with the prescribing eye-care professional, especially if symptoms persist or worsen. Production lead time is confirmed separately after RX, material, blank, coating, finishing, quantity and verification review.
Custom Ground-In Prism Prescription Lenses
Heritage Optical Lab supplies custom prism spectacle lenses for optical laboratories, retailers, distributors and eyewear brands after complete prescription and construction review. Available combinations can include single vision, compatible blue-filtering, photochromic, higher-index and CR-39 options.
Prism prescription data
Prism magnitude and base direction or angle must be supplied for each eye together with sphere, cylinder, axis and ADD where prescribed. Horizontal and vertical components, prism splitting, reference point and eye-side allocation must be unambiguous. Prism lenses are manufactured to a prescription issued and evaluated by a qualified eye-care professional.
Construction and thickness review
Ground-in prism shifts the observed image and creates an asymmetric thickness distribution. Material/index, Abbe value, blank diameter, base curve, frame trace, decentration, minimum center/edge thickness, mounting method and coating requirements are reviewed as one job. No fixed prism range or thickness-reduction percentage is promised before feasibility review.
External layout markings
Blue removable external markings identify alignment, optical or fitting references during laboratory inspection and dispensing. They are distinct from permanent engravings and are removed after verification.
Functional treatment options
Hard coat, anti-reflective, blue-filtering, photochromic and tint options are reviewed separately for material compatibility, color, transmission, durability and processing. Branded photochromic program availability must be confirmed for the selected material and market.
Verification and wholesale ordering
Finished lenses are checked for ordered sphere/cylinder/add power, prism amount and base direction at the agreed reference point, geometry, appearance and treatment criteria. ISO 8980-1 covers applicable optical and geometrical requirements for uncut finished single-vision and multifocal spectacle lenses.
