The carbon fiber arm is the newest type of eyeglass material, which is lighter than any other on the market. Tests have shown that carbon fiber glasses of the same size are about 30% lighter than titanium frames and less than a quarter of the weight of ordinary metal glasses, making them very comfortable and light to wear.
CARBON FIBER ARM - High strength, good toughness. High strength, good toughness. Carbon fiber, like diamonds, is made of carbon, so it's very tight and hard. Carbon fiber glasses are lighter than aluminum glasses, but harder than steel. They are more than 10 times stronger than iron. Carbon fiber is chemically stable, resistant to acid, alkali and salt. It is superior to other materials in anti-corrosion and can be kept intact in damp and harsh environment.
