When choosing a new pair of glasses or sunglasses, one of the most common questions is: which material lasts longer — TR90 or metal?
Both are popular frame materials, each with unique strengths. At Fondvue Glasses, we understand that durability, comfort, and design all play a part in finding your perfect eyewear. Here’s a clear comparison to help you decide which frame type fits your lifestyle best.
What Is TR90?
TR90 is a lightweight thermoplastic material originally developed in Switzerland. It’s known for being incredibly flexible, impact-resistant, and heat-resistant — perfect for people who live active lives.
Unlike ordinary plastic, TR90 can bend without breaking and quickly return to its original shape. That means fewer worries about accidental drops or bending your frames during daily use.
What About Metal Frames?
Metal frames, on the other hand, are made from materials such as stainless steel, titanium, or aluminum alloys. They’re prized for their slim profiles, refined appearance, and structural strength.
High-quality metal frames often feature spring hinges or adjustable nose pads for added comfort. However, depending on the alloy, some metal frames can be prone to bending or corrosion over time.
Durability Comparison: TR90 vs. Metal
When it comes to longevity, both materials perform well — but in different ways.
TR90 frames are highly resistant to impact, making them less likely to crack or snap if dropped. They’re also unaffected by sweat and humidity, which prevents corrosion. This makes them ideal for sports, travel, or outdoor activities.
Metal frames, especially titanium or stainless steel, can last for many years if properly cared for. They maintain their structure and polish, giving them a more premium, enduring feel. However, low-quality metal can rust or warp if exposed to moisture or extreme temperatures.
In simple terms:
TR90 lasts longer under active or rough use.
Metal lasts longer under careful, everyday use.
Comfort and Flexibility
TR90 frames are exceptionally lightweight — so light that many people forget they’re even wearing glasses. Their flexibility allows them to adapt to different face shapes without feeling tight or rigid.
Metal frames are generally heavier but more adjustable. Opticians can fine-tune the fit around the temples and nose for precise comfort, especially with adjustable nose pads.
Style and Aesthetic Differences
If you prefer a modern, sporty, or casual look, TR90 frames are a perfect choice. They come in a wide variety of colors, finishes, and shapes.
If you lean toward classic, elegant, or professional styles, metal frames provide a sleek and minimalistic appearance that never goes out of style.
Which One Lasts Longer Overall?
In terms of physical durability, TR90 frames tend to withstand rough handling and drops better than most metals. They’re nearly unbreakable in daily use and maintain their shape for years.
However, high-end metal frames — particularly titanium — are equally long-lasting when maintained properly. They can last for decades, offering a timeless, premium feel that some users prefer.
So, the answer depends on your lifestyle:
Choose TR90 if you value lightweight comfort, flexibility, and impact resistance.
Choose metal if you prioritize elegance, rigidity, and classic styling.
Final Thoughts
Both TR90 and metal frames offer excellent durability — just in different ways. TR90 wins in flexibility and impact resistance, while metal frames excel in structure and timeless appeal.
