TR90 is a high-performance thermoplastic material widely used in sports and premium eyewear.
It is engineered to be:
- Extremely lightweight
- Flexible under pressure
- Resistant to impact and deformation
For active users, this means the sunglasses can withstand bending, dropping, and long-term wear without losing shape.
Compared to traditional plastic or metal frames, TR90 offers a superior balance between comfort and durability, making it ideal for running, cycling, hiking, and daily commuting.
This material is one of the key reasons modern performance eyewear has become significantly more comfortable than older designs.
