Trifocal Lens Features and RX Customization
A dependable trifocal order combines the complete prescription with monocular PD, fitting height, frame measurements, lens design, material, coating and the wearer’s real distance, intermediate and near tasks.
OptoCalc Smart Trifocal Design Characteristics
OptoCalc Smart Trifocal is a specialist Freeform design for three defined viewing ranges. Its extended intermediate zone can be configured around a fixed reference distance of 0.8 m, 1.2 m or 1.8 m, while the distance, intermediate and near areas are reviewed as one complete design.
| Design characteristic | Smart Trifocal reference |
|---|---|
| Available corridor length | 13 mm |
| Fitting cross position | 4 mm |
| Recommended fitting height | 20 mm |
| Minimum fitting height | 18 mm |
| Inset | 2.5 mm |
| Centering chart | Chart A |
| Selectable intermediate reference | 0.8 m, 1.2 m or 1.8 m |
These values apply to the Smart Trifocal design and should not be treated as universal parameters for every conventional or Freeform trifocal lens.
From RX Data to a Manufacturable Smart Trifocal Lens
Submit R/L SPH, CYL, AXIS and ADD together with any prescribed prism/base information. Add monocular PD, fitting height, frame A, B, DBL, effective diameter and a frame trace when edging is required. Confirm the Smart Trifocal intermediate reference of 0.8 m, 1.2 m or 1.8 m. The laboratory then reviews the 13 mm corridor, 4 mm fitting cross position, 20 mm recommended fitting height, 18 mm minimum fitting height, material, coating, tint and finishing as one production specification.
Smart Trifocal Use Cases and Design Selection
Choose the intermediate distance from the real task
The intermediate reference should be stated before calculation. A shorter reference may support closer arm’s-length work, while a longer reference can suit tasks such as sports setup, counters, dashboards or viewing at greater indoor distances.
Confirm the design before applying fitting values
Smart Trifocal uses a 13 mm corridor, 4 mm fitting cross position, 20 mm recommended fitting height, 18 mm minimum fitting height and 2.5 mm inset. Conventional visible-segment trifocal designs require separate segment and fitting confirmation.
Submit the complete lens system
Provide R/L SPH, CYL, AXIS and ADD, prescribed prism/base, monocular PD, fitting height, frame data or trace, selected intermediate reference, material, treatment, tint and finishing service.

Repeat-Order Support
Confirmed design references and order records help simplify review and maintain consistency for subsequent orders.
Trifocal Lens Specifications and RX Ordering Guide
Smart Trifocal production requires the complete prescription, ADD, selected intermediate reference, monocular PD, fitting height, frame data and a compatible material and treatment specification.
- RX & Smart Trifocal Data
- Smart Trifocal Design
- Ordering Workflow
| Order input | What to provide | Why it matters |
|---|---|---|
| Prescription | R/L SPH, CYL, AXIS and ADD; prism/base when prescribed | Defines the required optical powers for each eye |
| Smart Trifocal design | 13 mm corridor, 4 mm fitting cross, 20 mm recommended and 18 mm minimum fitting height, 2.5 mm inset | Applies the verified Smart Trifocal design reference |
| Intermediate task | Select 0.8 m, 1.2 m or 1.8 m according to the intended use | Sets the fixed reference for the extended intermediate zone |
| Positioning | Monocular PD and fitting height | Positions the design relative to each pupil and frame |
| Frame data | A, B, DBL, effective diameter and frame shape or trace | Supports blank-size, thickness and edging review |
| Lens system | Material/index, diameter, coating, tint and edging requirement | Confirms a compatible production specification |
Final availability, thickness and production parameters are confirmed after the complete RX and frame data have been reviewed.
Smart Trifocal is selected as one complete design
The 13 mm corridor, 4 mm fitting cross position, 20 mm recommended fitting height, 18 mm minimum fitting height, 2.5 mm inset and Chart A centering reference belong to this specific design.
Material and treatment options
CR-39 and suitable higher-index materials, photochromic or prescription-sun configurations, hard coating, anti-reflective, hydrophobic, UV and blue-filter treatments can be reviewed where compatible with the complete RX and production specification.
Do not reuse the Smart Trifocal values for every design
Conventional visible-segment trifocals and other Freeform designs require their own segment, fitting and availability confirmation.
Confirm R/L SPH, CYL, AXIS, ADD and prescribed prism/base information.
Choose the supported 0.8 m, 1.2 m or 1.8 m intermediate reference from the intended task.
Check monocular PD, fitting height, frame dimensions or trace and Smart Trifocal minimum requirements.
Confirm the 13 mm corridor, material, treatment, tint and finishing before digital calculation and production.
Verify power, design positioning, appearance and finishing before packing and delivery.
Provide R/L SPH, CYL, AXIS and ADD values, any prescribed prism/base data, monocular PD, fitting height, frame measurements or trace, lens material/index, coating, tint and edging requirement.
Bifocal lenses generally provide distance and near vision. Trifocal lenses add a dedicated intermediate area for arm’s-length tasks such as desktop displays and dashboards.
Some Freeform trifocal designs support selectable intermediate references. The available value must be confirmed for the chosen design, prescription, frame and intended task.
A broad range of RX orders can be reviewed. Feasibility, material/index, diameter, frame choice and expected thickness must be confirmed before production.
Options may include CR-39, suitable high-index materials, photochromic or prescription-sun configurations, hard coating, anti-reflective, hydrophobic, UV and blue-filter treatments. Availability depends on the full specification.
Yes, where the order is technically feasible. Provide accurate frame measurements and preferably the frame trace so the laboratory can review blank size, thickness and edging requirements.
External appearance depends on the selected design. Smart Trifocal is a digitally calculated specialist design with an extended intermediate zone, while conventional segmented trifocals may show visible segment lines. Confirm the exact design before ordering.
Send the target RX range, ADD, selected 0.8 m, 1.2 m or 1.8 m intermediate reference, fitting data, frame information, material, treatment and destination market. The RX team reviews the program before confirming samples.
Yes. Once the design reference, working distance, fitting inputs, material, treatment, packaging and any special engraving marks are confirmed, the supported order records can simplify subsequent production review.
How Heritage Verifies Smart Trifocal Lens Orders
Each Smart Trifocal order is reviewed as one complete lens system so the prescription, intermediate reference, fitting data, frame, material and treatment remain aligned through production.
Confirm the complete RX, ADD, selected 0.8 m, 1.2 m or 1.8 m reference and prescribed prism data.
Review the 13 mm corridor, 4 mm fitting cross, fitting height, 2.5 mm inset and frame conditions.
Confirm material, diameter, coating, tint and finishing before production release.
Verify optical power, design positioning, appearance and the confirmed finishing requirements.
