Trivex vs High Index Lenses: Which Should You Choose?

Trivex lenses and high index lenses serve different needs: Trivex excels in optical clarity, impact resistance, and lightweight comfort, while high index lenses are best for achieving ultra-thin, lightweight lenses for strong prescriptions. The right choice depends heavily on prescription strength and the specific priorities for your eyewear.

 

Key Differences Between Trivex and High Index

Impact Resistance and Durability

Trivex lenses are superior when it comes to impact resistance and toughness. They were originally developed for military use, making them highly reliable in situations where durability is essential. Trivex is the go-to choice for sports eyewear, children’s glasses, and safety goggles because it resists cracking and shattering.

High-index lenses, on the other hand, are not as durable. While they perform well in everyday settings, they are more brittle and not recommended for environments where impacts are common. For users who need resilience and long-lasting durability, Trivex clearly outperforms high-index materials.

Optical Clarity

Trivex offers excellent optical clarity, thanks to a high Abbe value of around 43-45. This means wearers experience less chromatic aberration, the color fringing that can distort vision, particularly at the edges of lenses. People who are sensitive to visual distortions or who spend long hours reading or working on screens often notice the difference.

High-index lenses can provide good clarity, but they tend to have lower Abbe values. This results in more color distortion, particularly in higher index versions. Anti-reflective coatings can help reduce the issue, but for individuals who want the sharpest, most distortion-free vision, Trivex generally comes out ahead.

Thickness and Weight

For low-to-moderate prescriptions, Trivex lenses are among the lightest and most comfortable lens materials available. They reduce weight on the nose and ears, making them comfortable for all-day wear. However, as prescription strength increases, Trivex lenses become thicker.

High index lenses are specifically designed for strong prescriptions, generally above +/-4.00. They significantly reduce lens thickness and weight, helping minimize the “coke bottle” effect of thick lenses. For people with strong prescriptions, high-index lenses not only look better but also feel more balanced on the face.

Prescription Suitability

Trivex is the better choice for low-to-moderate prescriptions, rimless frames, custom luxury eyewear, or any eyewear that must be durable . Its combination of clarity, comfort, and strength makes it versatile for these scenarios.

High-index lenses shine for strong prescriptions. If you have a prescription of +/-4.00 or higher, high-index lenses will give you much thinner, lighter lenses, improving both comfort and appearance.

UV and Scratch Protection

Both Trivex and high-index lenses provide full UV protection. Trivex has the advantage of built-in UV blocking, while some high-index materials rely on coatings for protection. Both lens types are also resistant to scratches, though Trivex may last longer in demanding environments.

Cost

In terms of price, high-index lenses are typically the most expensive, especially at higher index levels like 1.67 or 1.74. Trivex lenses are moderately priced, sitting between polycarbonate and high index. While cost is an important factor, the benefits of thinner lenses or greater clarity may justify the investment depending on your prescription and needs.

Practical Recommendations

When to Choose Trivex

- For sports eyewear where impact resistance is crucial

- For rimless or drill-mounted frames where lens strength prevents cracking

- For adults with low-to-moderate prescriptions who value visual clarity and comfort

When to Choose High Index

- For strong prescriptions (+/-4.00 or higher) where lens thickness and weight are major concerns

- For wearers who prioritize aesthetics and want lenses that look thinner and sleeker

- For people who prefer lightweight glasses without the bulk of thicker materials

Real-World Scenarios

Everyday Wearers with Mild Prescriptions

For someone with a mild prescription, Trivex provides lightweight comfort and excellent clarity. The difference in thickness compared to high index is minimal at this level, so Trivex’s durability and sharper optics make it the better value.

Strong Prescriptions and Aesthetic Needs

For people with stronger prescriptions, high-index lenses reduce lens thickness dramatically. This not only improves appearance but also reduces the weight of the lenses, which can otherwise feel heavy in standard materials.

Pros and Cons of Trivex

Pros

- Superior impact resistance

- High optical clarity with minimal distortion

- Lightweight for low-to-moderate prescriptions

- Built-in UV protection

- Excellent scratch and chemical resistance

Cons

- Becomes thicker at strong prescriptions

- A higher price point  than polycarbonate

- Less widely available than high index in some designs

Pros and Cons of High Index

Pros

- Thinnest option for strong prescriptions

- Lightweight for higher corrections

- Aesthetic advantages, avoiding a thick-lens look

- Available in a wide range of lens designs

Cons

- More chromatic aberration due to a lower Abbe value

- Less impact resistant, not ideal for those who value durability.

- More expensive than Trivex and polycarbonate

- May require coatings for full UV protection

Conclusion: Trivex vs High Index

The choice between Trivex and high-index lenses comes down to prescription strength and lifestyle priorities. Trivex is best for people with low-to-moderate prescriptions who want lightweight, durable lenses with superior clarity. It is also ideal for children, athletes, and anyone in need of safety eyewear.

High-index lenses are the right choice for those with strong prescriptions who want the thinnest, lightest lenses possible. They provide a more aesthetically pleasing look and comfortable fit, though at a higher cost and with less durability than Trivex.

In summary, if your top concern is clarity, comfort, and durability, Trivex is worth considering. If your prescription is strong and you need thin, discreet lenses, high index will likely be the better investment. Discussing your prescription and lifestyle with your optician will help ensure you make the best choice for your vision needs.
