1.60 High-Index Clear Single Vision
A good candidate when you want a slimmer profile without automatically paying for a higher index. Suitable prescription and frame selection are important.

Both indexes describe optical materials. Neither is automatically the right choice for every prescription.
1.60 vs. 1.67 · Material and price comparisonTHE SHORT ANSWER
1.67 lenses have a higher refractive index than 1.60 lenses. They can often be made thinner for the same prescription and frame, especially when edge thickness is noticeable. The trade-off is usually a higher price; 1.60 may be a better value when your lenses are already reasonably thin. Neither index by itself guarantees lighter glasses, sharper vision or a fixed percentage thickness reduction.

| Comparison | 1.60 High Index | 1.67 High Index |
|---|---|---|
| Lens material index | 1.60 | 1.67 |
| Thickness potential | Thinner than standard 1.50 plastic in many comparable cases | Can be thinner than 1.60 in the same prescription/frame |
| RenewLens clear single-vision pair | $152.99 | $179.99 |
| Listed price difference | Base comparison | $27 more than listed 1.60 pair |
| Typical deciding factor | Value and sufficient thinness | More noticeable thickness concerns |
| Weight | Depends on finished geometry/material density | Not automatically lighter; finished shape matters |

HOW TO MAKE THE RIGHT CHOICE
A small, round frame usually requires a different lens shape and amount of material than an oversized rectangular frame. PD, optical-center position, cylinder/axis and lens minimum thickness also affect the outcome. This is why broad claims such as “1.67 is always 30% thinner” are unreliable without frame and prescription data.
Plus prescriptions often have thicker centers; minus prescriptions tend to have thicker edges. A useful material recommendation starts with these basics.

OTHER BUYING FACTORS
Higher index is not the only optical consideration. Material dispersion, coatings, prescription, lens design and fit all affect the experience.
Because lens density can differ, less thickness does not automatically mean less weight. Your exact finished frame/lens assembly matters.
1.60 and 1.67 describe material, not viewing design. Progressive lenses have separate fitting, corridor and measurement requirements.
CONSIDERING SOMETHING EVEN THINNER?
For some strong prescriptions, 1.74 high-index lenses can reduce thickness further, but they may cost more and are not available or appropriate for every design and mount. Choose based on your actual frame and prescription—not the highest index number alone. Read the 1.67 vs. 1.74 comparison →

QUICK ANSWERS TO POPULAR SEARCHES
In the same prescription and frame, 1.67 can often be made thinner because the material bends light more efficiently. Actual finished thickness depends on multiple measurements.
It may be worth it when reducing visible lens bulk is important. If your prescription and frame already yield thin lenses, 1.60 may offer better value.
The referenced 1.60 clear single-vision pair is $152.99 and the 1.67 pair is $179.99, a $27 difference before optional upgrades. Live listing/checkout prices control.
It can be suitable for some prescriptions in that range, but lens dimensions, cylinder, frame style, PD and your thickness expectations matter more than one sphere number alone.
A 1.67 material may be useful for thickness concerns in some stronger prescriptions, but the choice still depends on frame geometry, prescription and other optical requirements.
No. Finished weight depends on lens thickness, geometry and material density, and the lens with the higher index is not automatically lighter.
Both can produce excellent prescription eyewear, but their optical material properties may differ, including dispersion. Lens design, coatings and fitting also matter.
Often yes, subject to frame condition, material availability, prescription and mounting requirements. Specialty frames need additional assessment.
Yes. Lens size and optical centering can significantly affect edge thickness, especially for minus prescriptions.
Yes. RenewLens serves eligible customers in both states through its nationwide mail-in lens replacement process.
For some strong prescriptions, 1.74 is worth comparing. It can provide additional thinness but may have different cost or availability considerations.
