Its impact resistance is more than 10 times that of traditional resin lenses. At the same time, it can also block ultraviolet light by 100% and provide more comprehensive eye protection. Since people with presbyopic eyes are usually older and their eyes are more sensitive to light, these characteristics of PC lenses make them a practical and safe choice.

What is the difference between PC lenses and resin lenses?

PC lenses are more resistant to drops than resin lenses. They are not easily fragmented when subjected to strong impact, providing greater safety. 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.

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.

Weight difference: PC lenses are lighter and are currently the lightest optical lenses. The weight of PC lenses is about 30% lighter than ordinary resin lenses and 50% lighter than glass sheets. Price difference: PC lenses are generally more expensive than resin lenses. Impact resistance: PC lenses have 10 times stronger impact resistance than resin lenses.

The core difference between PC lenses and resin lenses lies in material characteristics and performance: PC (polycarbonate) is a thermoplastic engineering plastic, and 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.

Durability Comparison PC lenses (polycarbonate) have an impact resistance that is more than 10 times that of resin lenses. They can withstand greater external forces without rupturing and are suitable for sports or children. 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.

Are spectacle lenses made of PC strong impact resistance? Is it suitable to wear during exercise?

Glasses made of PC have very strong impact resistance and are the preferred material for sports glasses. PC lenses (polycarbonate) have an impact resistance that is more than 10 times that of ordinary resin sheets, which can effectively prevent the lenses from breaking during strenuous exercise. After being strengthened, these lenses can even withstand the impact of small-caliber bullets, so they are widely used in safety protection fields such as bulletproof glass and aerospace masks.

Glasses made of PC are light and impact-resistant and suitable for sports or children, but their wear resistance and optical properties are not as good as resin lenses. Material characteristics PC (polycarbonate) lenses have an impact resistance that is more than 10 times that of ordinary resin lenses and are about 20%-30% lighter. However, the surface hardness is low and it is easy to scratch, so hard coating is needed. The UV blocking rate is about 99%, and no additional UV coating is required.

Advantages and disadvantages of PC eyeglass lenses (polycarbonate lenses): Advantages: Strong impact resistance: The impact resistance of polycarbonate material is 10 times that of ordinary resin lenses, making it suitable for sports or children. Thin and thin: High refractive index (usually 59), thinner than ordinary resin lenses, suitable for people with high degrees. Ultraviolet protection: Naturally blocks 100% UVB and UVA without additional coating.

PC lenses and resin lenses have no absolute advantages and disadvantages, and the appropriate category needs to be selected according to the usage scenarios and wearing needs. The core differences and application scenarios between the two are as follows: Impact resistance and safety performance PC lenses have an impact resistance of more than 10 times that of ordinary resin lenses. They are not easy to produce sharp splashing fragments after being broken, and are more suitable for children, outdoor sports enthusiasts, etc. People who are prone to bumps; ordinary resin lenses have weak impact resistance and are easy to break after strong impact.

PC material eyeglass lenses have excellent impact resistance, but their surface hardness is low and they are easy to scratch. Daily use requires a coating process to improve durability. Impact resistance The impact resistance of polycarbonate (PC) material is more than 10 times that of ordinary resin lenses. It can withstand impact energy of about 80-100 joules. It meets the U.S. FDA impact resistance standards and is suitable for sports protection or children.

Which of PC eyeglass lenses and resin lenses is more resistant to scratches and leaves no scars?

1. PC eyeglass lensesWhat is an eye piece PC?, also known as polycarbonate tabletsWhat is an eye piece PC?, is a thermoplastic material. Its chemical name is polycarbonate, and the raw material is heated and shaped into lenses in the solid state. Therefore, if this lens is excessively affected after being finishedWhat is an eye piece PC?The heat may also be deformed and is not suitable for use in high temperature and humid environments. PC lenses are extremely tough and are not easy to break (they can be used as bulletproof glass when they reach a thickness of 2 centimeters), so they are also called safety lenses.

2. The shortcomings of resin lenses include: surface wear resistance, chemical resistance is worse than glass, surface is easy to scratch, and water absorption is greater than glass. These shortcomings can be improved by coating methods. The fatal shortcomings are high thermal expansion coefficient, poor thermal conductivity, low softening temperature, and easy deformation and affecting optical performance.

3. Wear resistance: The wear resistance of uncoated PC lenses is worse than that of ordinary resin lenses. Additional hard multilayer coatings are needed to improve scratch resistance. Price: The price of PC lenses of the same specification is generally 20%-50% higher than that of resin lenses. Scene adaptation guide Typical scenarios for selecting resin lenses: static eye scenarios such as daily office, reading, and screen viewingWhat is an eye piece PC?; glasses with high requirements for visual clarity; general glasses with limited budgets.

4. Irreversible appearance damage is prone to occur after excessive bending or scratching by sharp hard objects. In low temperature environments, brittleness increases, and the surface is easy to scratch. A supporting hard coating is needed to improve wear resistance. Light transmittance: Normally, it is about 88%-91%, and high-end coated models can be increased to about 92%. However, there is a natural risk of slight yellowing, and slight visual yellowing may occur after long-term wear.

5. Dyeing, discoloration, blue light prevention and other processes are mature, with a wide variety of options, and generally lower prices;PC lenses are slightly more difficult to process, and some lenses with special luminosity are less stocked and the cost is high. Other characteristics PC lenses have better heat insulation and ultraviolet protection properties, and are superior to resin in high temperature resistance; resin lenses have higher initial light transmittance, and their anti-yellowing aging technology is more mature, and the degree of yellowing after long-term use is lower.

6. Resin lenses generally use "hydrophobic and oil-repellent layers", which can be wiped directly with a mirror cloth, and the maintenance cost is lower. To give a practical example: For a glasses user who rides a bicycle every day, the resin lens may break and scratch the face when falling, while the PC lens can withstand an instantaneous impact of about 200 kilograms, which significantly improves safety. When the budget is sufficient, priority can be given to investing in PC lenses for functional scenarios, and daily spare resin lenses can be replaced.
