With the increase in the number of myopic people, the glasses on the market are also of various shapes and sizes, making it difficult to choose. It is said that the right glasses frame is the first step in refractive correction, but there are many materials for glasses frames, such as acetate glasses, TR90 frames, metal frames… For metal frames, everyone should be very familiar with them. Today, let’s talk about acetate frames and TR90 frames!
Acetate glasses are made of high-tech plastic memory plates. Most of the current acetate components are acetate fibers, and a few high-end frames are propionate fibers. The acetate type of acetate fiber is divided into injection molding type and pressed polishing type. The injection molding type, as the name implies, is cast in a mold. Acetate frames are also suitable for people with high degrees, because the frame is larger and can withstand high-degree lenses. However, traditional acetate glasses are heavier, especially when the degree is high. The lenses are thick, and the weight of the frame makes a pair of glasses very heavy. Sometimes people will feel dizzy after wearing them for a long time. Therefore, most of the current eyewear designers will consider the size and thickness of the glasses. Processed with fashion, lightest and most humanized comfort.
TR90 frame is a polymer material frame with memory, no chemical residue release, meets European requirements for food-grade materials, and is currently the most popular ultra-light frame in the world. TR90 frame has the characteristics of super toughness, collision resistance, wear resistance, and low friction coefficient, which 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. Moreover, the surface of TR90 frame is smooth, with a density of 1.14-1.15. It will float in salt water. It is lighter than other plastic frames, about half the weight of plate frames, and 85% of nylon materials. It can reduce the burden on the bridge of the nose and ears, and is suitable for teenagers.
So is acetate frame better or tr90 frame? In fact, acetate glasses and tr90 frames each have their own characteristics and advantages. If you are a fashionista, acetate frames may be more suitable. Because acetate frames are fashionable and easier to match with clothes, and the combination of acetate’s heaviness and metal texture can better reflect personality and style. On the contrary, if you are not a person who cares about appearance and have a large face, then TR90 frames are definitely a pair of glasses with good cost performance. Moreover, TR90 frames are currently widely used in many optical fields such as sunglasses, 3D glasses, polarized glasses, radiation-proof glasses, etc., and are an important material choice for many eyeglass frame brands.
