TR90 was produced through Swiss technology as a thermoplastic material that is incredibly durable, flexible, and lightweight. Glasses made with TR90 are extremely comfortable because they have a flexible quality. 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. If you’re guilty of constantly dropping your glasses, fear not! TR90 frames are tougher than most. The thermoplastic material has a barely-there feel that you truly have to wear to believe.
