Why Are Tr90 Optical Frames Called the Aristocracy Among Glasses?

For people with myopia, a pair of suitable frames is a necessary close companion, and "lightness" is one of the important indicators for choosing frames. Pure titanium memory frames and lightweight plate frames are undoubtedly designed for "lightness". TR90 Optical Frames make lightness a real visual enjoyment, and fundamentally realize the word "lightness".

TR-90 (plastic titanium) is a polymer material with memory. It is currently the most popular ultra-light frame material in the world. It has the characteristics of super toughness, collision resistance, wear resistance, and low friction coefficient. It can effectively prevent damage to the eyes and face caused by frame breakage and friction during exercise. Due to its unique molecular structure, it has good chemical resistance, is not easy to deform in a high temperature environment, can withstand 350 degrees high temperature in a short time, and is not easy to melt and burn.

TR90 Optical Frames have a lubricated surface and a density of 1.14-1.15. They will float in salt water and are lighter than other plastic frames, about half the weight of plate frames and 85% of nylon frames. They can reduce the burden on the bridge of the nose and ears and are suitable for teenagers. They are very wear-resistant, chemical-resistant, solvent-resistant, weather-resistant, non-flammable, and high-temperature resistant. Moreover, they are a high-molecular material with a deformation resistance index of 620kg/cm2 and are not easy to deform. Because TR90 frames are elastic and tough, not easy to break, strong, and not cracked, they are safe for sports. Moreover, they are very impact-resistant: more than twice that of nylon materials, ISO180/IC:>125kg/m2 elasticity, to effectively prevent damage to the eyes caused by impact during exercise. No chemical residue is released, which meets the European requirements for food-grade materials. TR90 materials are much more expensive than other pc, cp and other frame materials, and the production process is also more rigorous, so the price of TR90 frames is relatively high.

TR-90 stands for "Grilamid TR90". It was originally a transparent nylon material developed by EMS in Switzerland. Due to its various properties suitable for the production of frames, it has been widely used in the optical field in recent years (in fact, EMS also has a product called TR-55, but its characteristics are not suitable for frame products). TR90 is EMS's nylon 12 (PA12) and has the following advantages:

Light weight: about half the weight of the plate frame and 85% of the nylon material, reducing the burden on the nose bridge and ears, making it lighter and more comfortable to wear. Bright colors: brighter and more outstanding than ordinary plastic frames. Impact resistance: more than twice that of nylon materials, ISO180/IC: >125kg/m2 elasticity, to effectively prevent damage to the eyes caused by impact during exercise. High temperature resistance: can withstand 350 degrees high temperature for a short time, ISO527: anti-deformation index 620kg/cm2. Not easy to melt and burn. The frame is not easy to deform or discolor, making the frame longer to wear. Safety: No chemical residue is released, meeting European requirements for food-grade materials.

In addition to its ultra-light and wear-resistant characteristics, the reason why TR90 Optical Frames are so popular among fashionable men and women is also due to its variability. TR90 Optical Frames can be perfectly combined with other metals. The neat lines and bright colors bring fresh and vibrant outdoor energy to the dull city. Their addition makes the overall shape of the Tr90 frame more complete and colorful, providing a vivid lifestyle for street fashion fans. In addition to protecting the eyes, the Tr90 frame has become a fashion accessory. Deducing sports inspiration and showing elegant style, the light-generation Tr90 frame is a pair of frames exclusively for fashion trendsetters.
