If you wear reading glasses daily, you know the struggle: red marks on the bridge of your nose, sore ears, and the constant fear of accidentally sitting on them and snapping the frame.
In 2026, eyewear technology has solved these pain points with a revolutionary material: TR90. In this article, we’ll explore why TR90 has become the absolute favorite material for modern reading glasses.
TR90 is a thermoplastic material produced through Swiss technology. It is incredibly durable, flexible, and lightweight. Because of its unique properties, it is often referred to as "plastic titanium" or "memory plastic."
TR90 frames are extremely lightweight. Most TR90 reading glasses weigh less than 15 grams—about the weight of a few sheets of paper. You can wear them all day while reading or working on your computer without feeling any pressure on your nose or ears.
Have you ever bent your glasses by accident? TR90 has a high flexibility rating. It can bend under pressure and contour your face comfortably, then return to its original shape. This "memory" quality makes it highly resistant to breaking, making it perfect for daily use and travel.
Unlike cheap plastics that warp in the sun or degrade when in contact with skin oils and cosmetics, TR90 is highly resistant to heat and chemicals. It won't lose its shape or color even if left in a hot car during summer.
For those with sensitive skin, metal or cheap plastic frames can cause allergic reactions. TR90 is entirely hypoallergenic and safe for all skin types, ensuring a irritation-free wearing experience.
Reading glasses should enhance your lifestyle, not cause discomfort. By choosing TR90 frames, you are investing in comfort, durability, and modern style.
