1.61 Blue Block Airblue Coating SHMC Single-Vision Finished Lens

1. Outstanding Optical Performance    
Lightweight Design for Comfortable Wearing    
This lens features a refractive index of 1.61, which falls in the medium-to-high range within the refractive index system of resin lenses. Compared with lenses with lower refractive indices (such as 1.50 and 1.56), when correcting the same diopter, the 1.61 refractive index lens is thinner and lighter. This is extremely friendly for people with moderate to high myopia (400 degrees or above) or hyperopia—it not only reduces the overall weight of the glasses, eases the pressure on the bridge of the nose and ears, and greatly improves wearing comfort, but also improves the appearance issue caused by overly thick lens edges, making the glasses more aesthetic and exquisite.    

Clear Vision with Low Dispersion Guarantee    
Its Abbe number is usually 32. The Abbe number is used to measure the degree of lens dispersion; the higher the value, the smaller the dispersion. Although the Abbe number of the 1.61 Blue Block Airblue Coating SHMC lens is not particularly high, it still provides wearers with clear and natural visual effects in various daily visual scenarios, such as reading, watching TV, driving, and performing fine manual work. By effectively reducing phenomena like blurred color edges and rainbow light spots caused by dispersion, it alleviates eye fatigue and keeps the eyes comfortable at all times.    

High-Quality Lens Material    
Strong Impact Resistance for Safety and Reliability    
It is made of high-quality resin material. Compared with traditional CR-39 resin material, it is less likely to break when subjected to external impact, providing reliable safety protection for the wearer’s eyes. It is especially suitable for people with high daily activity levels who are prone to glasses collisions, such as athletes, students, and those who often engage in outdoor activities.    

Appropriate Specific Gravity and Excellent Comprehensive Performance    
The specific gravity of the lens material is approximately 1.30, which allows the lens to maintain a certain level of strength while being relatively light in weight, further enhancing wearing comfort. Moreover, this material also has good processing performance, which can meet the requirements of various complex lens processing technologies and ensure the precise molding and adaptation of the lens.    

2. Unique Airblue Coating and SHMC Technology    
Efficient Blue Light Protection    
In today’s era of widespread electronic devices, people are exposed to screens of computers, mobile phones, tablets, and other devices for long periods. These devices emit a large amount of high-energy blue light. The 1.61 Blue Block Airblue Coating SHMC lens can effectively neutralize and filter this high-energy blue light. Through special optical design and coating technology, it can selectively block blue light harmful to the eyes. Studies have shown that long-term exposure to high-energy blue light may increase the risk of retinopathy, and this lens can significantly reduce this risk, providing strong protection for eye health. Additionally, during the blue light filtering process, it does not affect normal color perception—wearers still see a bright and true-colored world, ensuring visual health without compromising the visual experience.    

Excellent Anti-Reflection Performance    
SHMC (Super Hydrophobic Multi-Coating), or super hydrophobic multi-layer coating technology, works in synergy with the Airblue coating to greatly reduce the reflection of light on the lens surface. Typically, it can reduce the lens reflectivity to an extremely low level, significantly improving the light transmittance of the lens. This allows more light to enter the eyes, making the objects seen by the wearer brighter and clearer. In high-light environments, such as direct outdoor sunlight or indoor exposure to strong reflection sources like computer screens and lights, it can effectively reduce reflections on the lens surface, avoid interference to the line of sight caused by reflections, and enhance the comfort and clarity of vision.    

Water-Repellent, Anti-Fouling, and Durable    
The SHMC technology endows the lens with excellent water-repellent and anti-fouling properties. The lens surface is like being covered with a nano-level protective film—water droplets and oil stains are not easy to adhere. On rainy days or when contaminated with oil, a gentle wipe can restore the lens to cleanliness and maintain good visual effects. At the same time, this multi-layer coating has good wear resistance, generally meeting the hardness standard of 6-8H. It can effectively resist scratches that may occur during daily use and extend the service life of the lens.    

UV Protection Function    
In addition to blue light protection, this lens can also effectively block ultraviolet (UV) rays. It can block 100% of UV rays, including UVA and UVB, preventing UV damage to the eyes and reducing the risk of eye diseases caused by UV radiation.
