● Effective Blue Light Filtration
1.56 blue block green coating lenses are engineered to offer reliable protection against harmful blue light. They can block approximately 40% of high-energy blue light within the 415 - 455 nm wavelength range, which is the most damaging part of the blue light spectrum. This is particularly beneficial for individuals who spend long hours in front of digital devices such as computers, smartphones, and tablets. 

● High Transmittance and Clear Vision​
Despite their blue-blocking capabilities, these lenses maintain a high light transmittance, typically around 96 - 98%. This ensures that a sufficient amount of light passes through the lens, providing wearers with a bright and clear view of their surroundings. High Transmittance and Clear Vision​

● Cost-Effective​
1.56 blue block green coating lenses offer a cost-effective solution for those seeking blue light protection and good optical performance. Compared to higher-index lenses with similar features, such as 1.61 or 1.67 index lenses, they are generally more affordable. Despite their lower cost, they do not compromise on important features like blue light blocking, clear vision, and durability, providing a great value for money option for protecting eye health while correcting vision.

● Blue block harmful blue Light.Features crystal blue film coating. The particles are more precise and effectively improve the performance of filter blue light reduction. 

● Lightweight and Comfortable: Made from high-quality resin materials, the 1.56 Blue Block Crystal Blue Coating Lenses are lightweight, reducing the burden on the nose and ears during extended wear. 

● Wear more comfortably and with higher light transmittance.

● Blue Light Blocking: It can effectively block a certain proportion of blue light. For example, some 1.56 blue block progressive lenses can block blue light, reducing the damage of blue light to the eyes and the risk of retinopathy. It is very suitable for people who use digital devices such as computers, mobile phones, and iPads for a long time, helping to relieve eye fatigue and discomfort.

● Graduated Focus: Progressive lenses have a graduated range of vision, with the top of the lens suitable for distance vision, the middle part for intermediate distances (such as computer vision), and the bottom for close-up activities like reading. This allows the wearer to view objects at different distances clearly without having to switch between different pairs of glasses.

● Anti-Reflection: The crystal blue coating usually has an anti-reflection function, which can reduce the reflection of light on the lens surface. This not only improves the clarity of vision but also reduces glare, making the wearer see more clearly and comfortably, especially in bright light environments or when looking at light sources.

● Integration of Progressive Multifocal and Photochromic Dual Technologies for All-Scenario Vision.

● There is no obvious dividing line on the lens. From top to bottom, it realizes a natural power transition, which conforms to the adjustment law of human eyes when viewing objects at different distances.

● Intelligent Light-Sensitive Photochromic Adaptation.The lens can automatically adjust the color depth according to the intensity light.It darkens quickly  under strong outdoor light to block excessive glare and ultraviolet rays;after entering a room, it fades automatically , without affecting the clarity of indoor vision, eliminating the need for frequent replacement lens.

● Blue block harmful blue light.Engineered to shield eyes from harmful high-energy visible (HEV) blue light emitted by smartphones, computers, tablets, and LED lights—while preserving beneficial blue light that regulates sleep and mood.

● It are engineered to effectively block a significant portion of harmful blue light. It can filter out approximately 40% of the high-energy blue light within the 400 - 500nm wavelength range.

● The HMC (Hard Multi Coating) on these lenses provides several benefits. Firstly, it offers excellent anti-reflective properties. The coating reduces the reflection of light on the lens surface by up to 90%. This means that less light is bounced back into the eyes, which not only improves the clarity of vision but also reduces glare. Secondly, the HMC coating is highly scratch-resistant. This durability ensures that the lenses maintain their optical clarity over an extended period, providing long-term value for the user.

● Violet coating can be used for driving lenses, anti-glare, and resisting UV damage.

● High refractive index: With a refractive index of 1.61, it is thinner and lighter than common 1.56 lenses, especially suitable for users with higher degrees, which can reduce the thickness and weight of the lenses and improve wearing comfort.

● Blue light blocking: It can effectively block harmful blue light emitted by electronic product screens, such as TVs, computers, mobile phones, and iPads, reducing the damage of blue light to the eyes and alleviating eye fatigue, dryness, and other symptoms.

● Lightweight and comfortable: Made of high-quality resin material, it is light in weight and almost imperceptible when worn.

● Durable and wear-resistant: The lens has good abrasion resistance and impact resistance. It is not easy to be scratched or damaged and has a long service life.

● Good light transmittance: These lenses usually have high light transmittance, which can ensure that the wearer has a clear field of vision and sees things clearly and naturally.

● Effective blue light blocking: They are coated with a special blue-blocking film that can effectively filter out a part of the harmful blue light emitted by electronic products such as mobile phones, tablets, and computers. This helps to reduce eye fatigue, dryness, and other discomforts caused by long-term exposure to blue light, and protects eye health.

● Thin and lightweight: With a refractive index of 1.61, these lenses are relatively thin and lightweight compared to lenses with lower refractive indices. They are more comfortable to wear and do not cause too much pressure on the bridge of the nose and ears, suitable for long-term wear.

● Good anti-ultraviolet performance: They can block 100% of ultraviolet rays, protecting the eyes from the harm of ultraviolet radiation and reducing the risk of eye diseases such as cataracts and retinopathy.

● Good anti-reflection performance: The SHMC coating has a good anti-reflection effect, which can reduce the reflection of light on the surface of the lens. This not only improves the visual clarity but also makes the glasses look more beautiful and reduces the trouble of glare.

● It allows for a seamless transition between different prescription powers within a single lens. The upper part of the lens is typically optimized for distance vision, enabling clear sight when looking at objects far away. The middle portion provides an intermediate power, which is useful for tasks like looking at a computer screen or reading street signs from a medium distance. The lower part of the lens is designed for near-vision activities, such as reading books, newspapers, or using a mobile phone. This eliminates the need to switch between different pairs of glasses for various visual tasks, providing convenience and a more natural visual experience.

● With a refractive index of 1.61, these lenses are relatively thin and lightweight compared to lenses with lower refractive indices, such as 1.50 or 1.56. The high refractive index allows the lens to bend light more efficiently, meaning that the same corrective power can be achieved with a thinner lens. Thinner lenses are less likely to cause pressure on the nose and ears, reducing the discomfort associated with wearing glasses for long periods. 

● Convenient and offers a younger appearance.

● Blue block harmful blue light.

● Use PU63 material for durability. High light transmittance and low dispersion, clear vision, and enjoy a new visual experience.

● Lightweight and Impact-Resistant
The PU63 material is lighter and thinner than traditional resin lenses. It exerts less pressure on the bridge of the nose and ears when worn. At the same time, it has excellent impact resistance and is not easy to break when collided with or dropped in daily use.

● Exceptional Durability and Easy Maintenance
The SHMC (Super Hydrophobic Multi-Coating) top layer provides a tough, scratch-resistant surface that strongly repels water, dust, and oils. This makes the lenses exceptionally easy to clean and maintain, ensuring long-lasting performance and clarity.
