1.53 Trivex vs 1.67 High Index Lenses: Which Should You Choose?

Comparing 1.53 Trivex lenses versus 1.67 high index lenses highlights trade-offs between thickness, optical clarity, impact resistance, and suitable prescription range. Trivex provides superior impact resistance, durability, and optical clarity, making it best for mild to moderate prescriptions, children, and active lifestyles. In contrast, 1.67 high index lenses are thinner, lighter, and more aesthetically appealing for stronger prescriptions, although they come with slightly more distortion and lower impact resistance. The right choice depends on whether safety and clarity or thinness and aesthetics are your top priority.

Key Differences Between 1.53 Trivex and 1.67 High Index

Refractive Index and Thickness

The refractive index determines how efficiently a lens bends light, which directly impacts lens thickness. The higher the refractive index, the thinner the lens can be for the same prescription.

1.67 high index lenses have a significantly higher refractive index than Trivex (1.67 vs 1.53), which allows them to be much thinner and lighter in stronger prescriptions. For prescriptions above +/-4.00, the difference in thickness becomes highly noticeable. Thinner lenses are not only lighter but also reduce the bulky “coke bottle” effect at the edges, offering a more attractive profile.

Trivex lenses, with a refractive index of 1.53, are relatively thicker in stronger prescriptions. However, for mild to moderate prescriptions (roughly +2.00 to -3.00), the difference in thickness between Trivex and 1.67 high index is minimal. In this range, Trivex’s advantages in clarity and safety outweigh the need for thinner lenses.

Weight and Comfort

Both 1.53 Trivex and 1.67 high index lenses are considered lightweight compared to older materials such as CR-39 or glass. However, the balance between the two changes depending on prescription strength.

Trivex is one of the lightest lens materials available for low to moderate prescriptions. Its low density reduces strain on the nose and ears, making it an excellent option for those who wear glasses all day. Many users describe Trivex lenses as “barely noticeable” due to their comfort.

At stronger prescriptions, however, 1.67 high-index lenses often end up being lighter overall. Because they require less material thanks to their thinner design, high-index lenses reduce both the weight and thickness of the glasses, making them more comfortable for people with high prescriptions.

Optical Clarity

Trivex excels in optical clarity due to its higher Abbe value, around 43-45. The Abbe value measures how much chromatic aberration a lens produces. A higher value means less distortion and sharper vision across the entire lens. Trivex lenses provide clearer peripheral vision and reduce color fringing, making them particularly valuable for users sensitive to visual distortion.

1.67 high index lenses, while thinner and lighter, have lower Abbe values. This increases the chance of chromatic aberration, which appears as color fringes or slight blurring at the lens edges. Although many wearers adapt quickly and do not notice this in everyday use, users with demanding visual needs or sensitivity to distortion may prefer Trivex for superior clarity.

Impact Resistance and Durability

Trivex was originally developed for military applications, giving it exceptional impact resistance. It is shatter-resistant and durable, making it an ideal material for, sports glasses and rimless or semi-rimless frames. In these settings, the added safety of Trivex far outweighs its slightly thicker profile.

1.67 high-index lenses, while durable enough for everyday use, are not as impact-resistant as Trivex. They are more prone to cracking or chipping under stress, which makes them less suitable for high-risk environments, active users, or rimless designs. For people who prioritize durability, Trivex is clearly the superior option.

Prescription Suitability

Prescription strength is often the deciding factor between Trivex and high-index lenses.

• Trivex (1.53): Best suited for mild to moderate prescriptions in the range of +2.00 to -3.00. Within this range, Trivex lenses provide the perfect balance of clarity, comfort, and durability without the need for the ultra-thin profile of high index lenses.
  
  

• 1.67 High Index: Designed for moderate to strong prescriptions above +/-4.00. In these cases, the thinner lens profile greatly improves comfort and aesthetics, reducing lens bulge and weight.
  
  

Price

On average, both Trivex and 1.67 high-index lenses are in a similar price range, although high index lenses can sometimes be at a higher price point due to the manufacturing process required for thinner profiles. For users with strong prescriptions, the aesthetic and comfort benefits of high index may justify the higher cost. For users with mild prescriptions, Trivex typically offers more value.

Real-World Applications

Children and Safety Eyewear

Parents often choose Trivex for children’s glasses because of its durability and shatter resistance. It provides peace of mind that lenses can withstand accidents, drops, or impacts. Similarly, athletes and construction workers rely on Trivex for its combination of clarity and safety.

Professional and Fashion Eyewear

High-index lenses are often the preferred choice for professionals or those wearing designer frames. The thin profile enhances the aesthetics of the glasses, making them less bulky and more visually appealing. For those with strong prescriptions, high-index lenses create a more polished look without compromising comfort.

Everyday Glasses with Mild Prescriptions

For people with mild prescriptions who wear glasses daily, Trivex provides excellent clarity and lightweight comfort. The difference in thickness compared to high index is negligible at this level, so Trivex’s superior optical performance and durability make it the smarter choice.

Strong Prescriptions and Aesthetic Needs

For those with strong prescriptions, 1.67 high-index lenses are great at reducing lens thickness and weight. They help prevent glasses from sliding forward and improve overall balance.
