Who We Support
CR-39 Lens Options for Different Customer Needs
Select the optical design, light-management option, coating and finishing from the prescription, frame, intended use and destination-market requirements.
A clear CR-39 option with compatible blue-filter material or treatment. Exact spectral performance and residual color depend on the selected product and coating.
A CR-39 photochromic option that remains clear indoors and darkens outdoors. Activation depends on UV exposure, temperature and the selected product.
A classic high-clarity material for supported single vision prescriptions, available with compatible hard coating and anti-reflective treatment.
A Freeform progressive CR-39 option calculated from the prescription, addition, fitting data, frame and selected design.
A high-base CR-39 option for selected wrap-style and non-impact applications. Prescription range, frame geometry and required impact standard must be reviewed.
CR-39 accepts a wide range of fixed tints. Color and visible-light transmission should be selected for the actual use environment.
Is CR-39 the Right Material for This Prescription?
CR-39 offers clear optics and relatively low chromatic dispersion, but its 1.499 index may create more thickness at stronger powers. Review lens power, cylinder, decentration, blank diameter, frame size and thickness target before confirming the material.
Where impact resistance is a priority, confirm the applicable safety requirement and consider polycarbonate, Trivex or another compliant lens system.
Customize Your CR-39 Lens Offering
- Compatible anti-reflective and hard-coating options
- Heritage low-reflection coating: an SDC-tested sample recorded reflectance as low as 0.45%; actual results vary by specification and test conditions
- Supported Bluecut and photochromic CR-39 programs
- Fixed tints with a specified color or transmission target
- Uncut or edged finishing where supported
These options help optical businesses build differentiated lens programs for everyday, screen-related, outdoor and fashion requirements. Final availability is confirmed against the prescription, material, diameter, coating stack, frame and finishing method.
RX Production and Final Inspection
The RX team verifies the prescription and order specification before production. Surfacing, coating and finishing follow the approved lens program, and finished lenses are checked for ordered power, appearance and required production data before release.
For complex prescriptions or special treatments, manufacturability and lead time are confirmed separately.

- CR-39 Material Facts
- Material Comparison
- How to Order
| CR-39 material fact | Typical value | Why it matters when ordering |
|---|---|---|
| Material | Thermoset allyl diglycol carbonate resin | Classic organic ophthalmic lens material |
| Refractive index | 1.499 | May be thicker than higher-index materials at stronger powers |
| Abbe value | 58 | Relatively low chromatic dispersion |
| Density | 1.32 g/cm³ | Useful when comparing weight with other lens materials |
| Color options | Clear, compatible photochromic | Specify color and visible-light transmission target |
| Finishing | Uncut or edged where supported | Provide diameter or complete frame dimensions and trace |
Values are typical reference data. Exact product specifications depend on the selected lens formulation and treatment.
| Lens material | Typical index / Abbe | Best fit | Main ordering consideration |
|---|---|---|---|
| CR-39 | 1.499 / 58 | Everyday RX lenses, clear or tinted programs | Can be thicker at stronger powers; review impact requirements |
| Polycarbonate | 1.586 / about 30 | Impact-sensitive and selected safety applications | Lower Abbe value than CR-39; confirm the required standard |
| Trivex | About 1.53 / about 44 | Low weight with higher impact performance | Availability and design range require review |
| High index | 1.60, 1.67 or 1.74 / varies | Stronger prescriptions and thinner-lens targets | Material, frame size, coating and thickness must be evaluated together |
Typical material values are reference data and may vary by formulation, supplier and measurement standard. The complete prescription, frame and intended use determine the final recommendation.
- Send the complete RX: right and left SPH, CYL, AXIS, ADD and prescribed prism/base.
- Select the design: single vision, bifocal, progressive or another supported design.
- Add fitting and frame data: monocular PD, fitting height, A, B, DBL, effective diameter and preferably a frame trace.
- Specify the lens system: clear, Bluecut, photochromic or tint, plus coating and finishing.
- Confirm business requirements: quantity, packaging, destination country and expected monthly volume.
After review, the RX team confirms manufacturability, available combinations and the quotation before production.

Yes. Supported programs can include custom packaging, lens envelopes, labels and private-label requirements. Confirm artwork, language, quantity and destination before production.
CR-39 is a thermoset organic ophthalmic lens material. A typical clear CR-39 lens has a refractive index of about 1.499, an Abbe value around 58 and a density around 1.32 g/cm³; exact values can vary by formulation and supplier.
CR-39 combines clear optics, relatively low chromatic dispersion, broad tint compatibility and competitive material cost. It is a practical choice for many everyday prescriptions when lens thickness and impact requirements are suitable.
CR-39 generally has a higher Abbe value, while polycarbonate and Trivex offer higher impact resistance. Polycarbonate is thinner at the same power because of its higher index; Trivex combines low density with higher impact performance. Select the material from the prescription, frame, use and required safety standard.
It can be used for supported prescriptions, but its lower refractive index may produce a thicker lens at stronger powers. A 1.60, 1.67 or 1.74 material may be more appropriate after the prescription, frame size, decentration and thickness target are reviewed.
Supported CR-39 programs can include compatible Bluecut, photochromic and fixed-tint options. Color, activation, visible-light transmission and residual reflection depend on the selected lens and coating system.
Provide the complete right and left prescription, optical design, monocular PD and fitting data where required, frame dimensions or trace, diameter, coating or color requirement, finishing method, quantity, packaging and destination country.
