What is the difference between the TR90 and a PC glasses frame?

The difference between TR90 and PC glasses frame is mainly reflected in material characteristics. First, TR90 is a highly elastic memory plastic material, while PC (polycarbonate) is a lightweight and durable plastic. The following is a detailed comparison of the two materials: Characteristics of the TR90 eyeglass frame: -Lightweight and comfortable: Due to its lightweight characteristics, the TR90 material exerts less pressure on the bridge of the bridge and ears when worn, giving people a comfortable experience.

- Durable elasticity: TR90 has good elasticity and can be bent under force without being easy to break. It has certain durability. - Anti-allergic: TR90 may be a better choice for some people because it may cause fewer allergic reactions in people with sensitive skin.

TR90 and PC are two popular eyeglass frame materials, each with its own advantages and disadvantages. Here are their main features to help you make your choice: Characteristics of the TR90 material: -Lightweight and comfortable: The TR90 material is comfortable to wear due to its lightweight design, reducing pressure on the bridge of the bridge and ears. - Elastic and durable: This material has good elasticity and can bend when subjected to pressure without easily breaking. It has certain durability.

TR90 and PC are two popular glasses frame materials. They differ in characteristics, and which material you choose depends on personal preferences and needs. Here is a detailed comparison of the two materials: TR90 Material: -Lightweight and comfortable: TR90 Material feels comfortable when worn due to its lightweight properties, reducing pressure on the bridge of the nose and ears.

Because the spectacle frame made of TR90 material has high elasticity, strong toughness, is not easy to break, has high strength and does not break, it has sports safety. Moreover, it is very resistant to impact: more than twice that of nylon material, and ISO180/IC: 125kg/m2 elasticity to effectively prevent eye damage caused by impact during exercise. No chemical residues are released and meet European requirements for food grade materials.

What material is good for glasses frames?

1. The advantages of β-TITANIUM (β titanium) material are: good flexibility, not easy to deform, and light weight. The disadvantage is that some beta-titanium temples are thin and soft and may not be suitable for people with high myopia. 1 The advantages of pure titanium include: light and durable, strong corrosion resistance, firm plating, not easy to fade, and not easy to deform. It is suitable for people with metal allergies. 1 Its shortcomings are: processing is difficult and the price is relatively high.

2. TR90 material: It is the most cost-effective and comfortable basic style. It weighs only 1/3 of that of an ordinary plastic frame. It is extremely flexible and can recover quickly after being bent. It will not press the bridge of the nose and behind the ears. It will be worn for a long time without strangulation; The color range is extremely wide, ranging from translucent clear models to matte pure colors. It is versatile and suitable for student parties and daily commuters. The common price is 100-300 yuan.

3. Advantages: Metals such as stainless steel/titanium alloy are comparable to the "hexagonal warriors" in the optical industry, and it is difficult to deform and crack the frame when beaten daily. Especially beta titanium, which has both the flexibility of memory metal and the rigidity comparable to steel, and is not easy to slip when worn during exercise.

4. The frame materials of sunglasses are diverse, which can be mainly divided into the following types: Plastic material: - PC (polycarbonate): The frame of this material is strong and durable, not easy to break, and has strong impact resistance. It is often used for sports sunglasses. - Acrylic (AC): Acrylic frames are light in weight, have good fog resistance and high light transmittance. Glass material: -Glass lenses have high transparency, but are heavier and fragile compared to resin lenses.

What material is the eyeglass frame more resistant?

1. The most durable frame material is titanium alloy (beta titanium or pure titanium), which combines lightness and corrosion resistance and is suitable for daily high-intensity use. Whether the frame is durable or not is essentially a comprehensive competition of materials in terms of deformation resistance, corrosion prevention and weight control.

2. If the budget is slightly higher, you can choose beta titanium. It is softer than pure titanium. It can quickly restore its original shape after bending. It has good corrosion resistance. If you sweat too much, you don't have to worry about oxidation and fading of the frame. Wear comfort.

3. The most durable frame materials are titanium alloy and TR90, which have strong resistance to compression and deformation and are suitable for high-frequency users. When wearing glasses, the frame material directly determines the service life and comfort. Problems such as metal breakage and plastic deformation are common in life, but in fact, they can be avoided in advance based on material characteristics. Titanium alloy: The strength of the "hexagonal warrior" titanium alloy frame in the lightweight anti-manufacturing world is about twice that of ordinary metal, but the weight is 40% lighter.

4. -Disadvantages: Not suitable for people with high degrees (the front end of the frame is too heavy and easy to slide, and the lens is too thick, which affects the appearance), cannot be adjusted, the material cost is high, the processing is difficult, and the price is high. Summary: When selecting glasses frame materials, pure titanium and beta titanium materials are outstanding in terms of durability. They are characterized by high strength, not easy to deform, light weight and low risk of metal allergy. However, these materials are costly.
