Choosing the right eyeglass lenses can significantly impact your vision clarity, comfort, and overall experience. Among the well-known options are Trivex and Polycarbonate lenses, both recognized for their durability and lightweight characteristics.
This article explores the differences between Trivex and Polycarbonate lenses, providing you with the information needed to make an informed decision.
Overview
Trivex and Polycarbonate lenses are both celebrated for their impact resistance and lightweight design, making them perfect for applications such as sports and children’s eyewear. Despite their similarities, they differ significantly in optical clarity, durability, and cost, which may affect your decision.
Two Materials Comparison Table
Feature | Trivex Eyeglass Lens | Polycarbonate Eyeglass Lens |
Material | Urethane-based monomer | Thermoplastic polymer |
Optical Clarity | Higher clarity and sharper vision | Good clarity but slightly less than Trivex |
Abbe Value | Higher (approx. 45) – less chromatic aberration | Lower (approx. 30) – more chromatic aberration |
Durability | Highly durable and less prone to stress fractures | Highly durable but can be more prone to stress fractures |
Scratch Resistance | Generally more scratch-resistant than polycarbonate | Good scratch resistance, but typically requires coating |
Cost | Generally more expensive | More affordable |
Trivex Eyeglass Lens
Trivex lenses offer higher clarity and less chromatic aberration due to a high Abbe value (45). They are durable, scratch-resistant, slightly heavier, and more expensive than polycarbonate, ideal for active lifestyles.

Polycarbonate Eyeglass Lens
Polycarbonate lenses provide good clarity with more chromatic aberration (Abbe value 30). They are impact-resistant, lighter, and more affordable than Trivex but require scratch-resistant coatings for better durability.

Which Lens is Better for You?
Your selection between Trivex and Polycarbonate lenses is contingent upon your unique requirements and personal preferences. To facilitate a knowledgeable decision, here are some factors to consider:
Budget
If cost is a significant factor, Polycarbonate lenses might be the more suitable option due to their affordability. They provide excellent performance at a lower price point, making them an economical choice for many users.
Optical Quality
For those who prioritize superior optical clarity and minimal chromatic aberration, Trivex lenses are the better choice. With a higher Abbe value, Trivex lenses offer sharper vision and reduced distortions, enhancing overall visual quality.
Durability and Impact Resistance
When it comes to durability, especially for high-impact activities or eyewear for children, both Trivex and Polycarbonate lenses perform excellently. However, Trivex lenses have an edge as they are less prone to stress fractures, offering better long-term durability.
Weight and Comfort
If lightweight lenses are crucial for your comfort, particularly for prolonged wear, Polycarbonate lenses are lighter and may offer better comfort throughout the day. This makes them ideal for those who wear their glasses continuously and require a lightweight option.
Scratch Resistance
Trivex lenses typically offer superior scratch resistance without requiring extra coatings. This enhances their longevity and maintains their clarity over time, making them a more durable choice for users who are concerned about lens scratches.
Usage Environment
Take into account the usual settings where you will wear your glasses. For active or outdoor environments, both lens types offer impact resistance, but Trivex may offer an added level of durability. For everyday indoor use, polycarbonate’s lightweight nature may be more beneficial.
Lens Thickness
While both lenses are thin, Trivex lenses tend to be slightly thicker than Polycarbonate lenses. If ultra-thin lenses are a priority for aesthetic or comfort reasons, Polycarbonate lenses may be the preferred option.
Visual Requirements
If you have specific visual requirements, such as high prescriptions, the enhanced optical clarity of Trivex lenses can provide a more comfortable and clear viewing experience, minimizing visual distortions and eye strain.
Conclusion
Both Trivex and Polycarbonate lenses have their own set of advantages and drawbacks. Trivex lenses excel in optical clarity and durability, while Polycarbonate lenses are cost-effective and lighter. Assessing your priorities in terms of budget, optical quality, durability, and comfort will guide you to the best choice for your eyeglass lenses. Whether you prioritize clarity or cost, both options provide reliable performance for a range of eyewear needs.
