TR90 is a
thermoplastic material that is incredibly durable, flexible, and lightweight.
Frames made with TR90 are extremely comfortable. Since they are flexible, they
can bend under pressure and contour your face comfortably. This flexibility
also makes TR90 glasses resilient to damage. Because the material is pliable,
they are far less likely to break or bend from impact. And most remarkable of
all, TR90 glasses are supremely lightweight! We’re proud to introduce our
latest collection of TR90 frames!
