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!
