In the previous article, we discussed “Who should wear low bridge glasses?“. In this article, let’s talk about “Can TR90 frames be adjusted?”.
Features of TR90 Frame
It has the characteristics of wonderful toughness, crash resistance, wear resistance, and low friction coefficient, which can effectively prevent damage to the eyes and face caused by the fracture and friction of the frame during the movement. Because of its specific molecular structure, and chemical resistance, it is not easy to deform in a high-temperature environment. It's very elastic, and it doesn't deform. The use of thermoplastic materials in these frames provides pretty strength due to their flexible characteristics.
What are the benefits of the TR-90?
Impact resistance is more than 2 times of nylon material, in order to effectively prevent the damage to the eyes caused by impact in the movement. It has high-temperature resistance. It's very elastic, and it doesn't deform.The use of thermoplastic materials in these frames provides pretty strength due to their flexible characteristics. It is not easy to deform and change color, making it wear for a longer time. Having no release of chemical residues, it is in line with the European requirements for food-grade materials. The weight is less than half of the weight of the plate frame, 85% of nylon material, reducing the burden of nose bridge, ears, and making wearing more comfortable.
Can the TR90 frame be changed?
TR90 material was originally made in Italy. It is difficult to color the frame, and usually, the color is painted on the outside. It can float in saltwater. It is suggested that the lens should be a water first to prevent overheating of the lens. Then, at the end of the nose, hinge, or the temple, carefully fold it in until it is comfortable to wear. You can use a household hair dryer to blow heat first, which can play the role of softening. Note that the hairdryer should be moved when heating, and do not aim at only one place. TR-90 is the most popular ultra-light material in the world at present.
