What are PC lenses? What is the difference between it and resin lenses?

1. PC lenses and resin lensesPC UV protection videoThe core difference lies in material characteristics and performancePC UV protection video: PC (polycarbonate) is a thermoplastic engineering plasticPC UV protection video, the resin (CR-39) is a thermosetting plastic. Material characteristics PC lenses are made of polycarbonate and have high impact resistance (about 10 times that of resin). They are often used in sports goggles or children's glasses.

2. The main differences between PC lenses and resin lenses are material characteristics, weight, impact resistance and price. Material characteristics PC lenses (polycarbonate) are thermoplastic materials, and resin lenses are thermosetting materials. PC lenses have a denser molecular structure and have an impact resistance that is more than 10 times that of resin lenses. They are often used in sports goggles or children's glasses.

3. PC lenses are more resistant to falling than resin lenses. They are resistant to fragmentation when subjected to strong impact and providePC UV protection videoHigher security. PC lenses have very good light transmission, with a light transmission rate of 92%, which ensures clarity of vision and is more conducive to eye protection. PC lenses are lighter than resin lenses and provide a more comfortable experience when worn, making them especially suitable for users who wear glasses for a long time.

4. PC lenses are short for polycarbonate, and PC lenses are also called space films. They are very light.

5. When choosing lenses, many people prefer PC lenses. PC lenses are known for their lightweight properties and are currently the lightest optical lenses on the market. They are about 30% lighter than ordinary resin lenses and more than 50% lighter than glass lenses. In terms of price, PC lenses are usually more expensive than resin lenses. PC lenses perform excellent in impact resistance. Their impact resistance is 10 times that of resin lenses and more than 60 times higher than glass lenses.

6. The wear resistance of resin lenses is usually better than that of PC, but a wear-resistant layer needs to be added to improve the surface hardness, otherwise it will be easy to scratch. Optical performance differences The Abbe number (dispersion coefficient) of resin lenses is generally between 30 and 40, which is higher than 29-32 for PC lenses. The imaging is clearer and the edge dispersion is less. The light transmittance of PC lenses is about 87%-90%, and the resin lenses can reach more than 92%, especially under strong light, which provides better visual comfort.

What is PC material?

1. --PC (polycarbonate), hot water cannot be filled. It is common in kettles, space cups, and milk bottles. Department stores often use water cups made of this material as gifts.

2. PC material is a polycarbonate material, a tough thermoplastic resin. The following is a detailed description of it: Basic characteristics Appearance and optical properties: colorless and transparent, with a high refractive index, which makes it excellent in applications requiring good optical performance, such as optical instruments, eyeglass lenses, etc.

3. PC material is a polycarbonate material, a tough thermoplastic resin with the characteristics of colorless and transparent, heat resistance, impact resistance, flame retardant, high refractive index, and good processing properties. The following is a detailed introduction to PC materials: Basic characteristics Physical properties: PC materials are colorless and transparent solid with a light transmittance of 89%, which is close to the transparency of inorganic glass.

4. Polycarbonates (PC for short) are high molecular polymers containing carbonate groups in their molecular chains. They can be divided into aliphatic, aromatic, aliphatic and aromatic types based on the structure of the ester groups. Among them, aliphatic and aliphatic-aromatic polycarbonates have low mechanical properties, which limits their application in engineering plastics. Only aromatic polycarbonates have been industrially produced.

5. PC material, namely polycarbonate material, is a tough thermoplastic resin. The following is a detailed introduction to PC materials: Basic characteristics Physical properties: PC materials are colorless and transparent, have high light transmittance (close to inorganic glass), and have a high refractive index, which can meet the needs of optical components. It has excellent impact resistance, which is 250-300 times that of ordinary glass, and has strong resistance to thermal distortion, and the thermal deformation temperature can reach 130-140℃.

Advantages of PC lenses

The advantages of PC lenses mainly include extremely strong strength, light weight, high impact resistance, 100% UV protection and good dispersion control; the disadvantages include not being suitable for high-humidity and heat applications, becoming brittle in cold environments, and light transmission. Slightly low and relatively poor wear resistance. Advantages: Extreme toughness: PC lenses have extremely strong toughness and are not easy to break, so they are also called safety lenses and are suitable for occasions requiring higher safety.

PC lenses are light in weight and thin in thickness, which can significantly reduce the pressure on the bridge of the nose and are suitable for long-term wear.

The advantages of PC lenses mainly include light weight, strong impact resistance, and strong ultraviolet protection, while the disadvantages are non-wear resistance, large dispersion and high processing costs. PC lenses, also known as "space films" or "universe films", are more than 30% lighter than ordinary resin lenses, which can greatly relieve the pressure on the bridge of the bridge of the nose and make it more comfortable to wear for a long time.
