● Adaptive Light Response​
1.56 photogrey green coating lenses feature remarkable photochromic properties. They can rapidly adjust to varying light conditions. In bright sunlight, these lenses darken. Conversely, when moving indoors or to a shaded area, they fade back to a clear state. This adaptability means wearers don't need to carry separate pairs of regular glasses and sunglasses, as these lenses seamlessly transition between different lighting environments, providing consistent visual comfort throughout the day.

● Enhanced Optical Clarity
Green coating is applied to the lens surfaces to manage reflections. Improved Light Transmission: Allows more light to pass through the lens, resulting in sharper, more comfortable vision, especially in low-light conditions or when the lenses are in their clear state.

● Durable and Scratch-Resistant​
Typically made from high-quality resin materials, these lenses are designed to be durable. The surface is often coated with a hard-coating layer, which can resist scratches with a rating of 6 - 8H. This hard coating not only protects the lens from daily wear and tear, such as minor impacts and abrasions, but also helps to maintain the optical clarity of the lenses over time.

● The Ultimate Convenience: Glasses & Sunglasses in One
The "Photogrey" lens material is reactive to ultraviolet (UV) light. It automatically darkens when you go outside and clears up when you return indoors. Eliminates the need to carry a separate pair of prescription sunglasses, making it incredibly convenient for everyday activities.

● High Light Transmission for Great Vision​
Even though they can filter light, 1.56 photogrey blue coating lenses still let a lot of light through. When they’re clear indoors, the amount of light they let through can be as high as 96% to 98%. This makes sure enough light passes through the lens, so you can see your surroundings brightly and clearly. The blue coating on the lenses doesn’t just help with the photochromic function; it also reduces reflections. The anti-reflection feature of the blue coating works really well to cut down on glare from both natural and artificial light sources. Whether you’re reading, working on a computer, or driving, these lenses give you sharp vision without distortion, making contrasts better and letting you see colors accurately.

● Ultra-Fast Light Adaptation​
1.56 photogrey (fast change) airblue coating SHMC lenses are equipped with advanced photochromic technology that enables them to adapt to light changes at an astonishing speed. In contrast to regular photochromic lenses that might take tens of seconds to fully darken, these lenses can start darkening within just 5 - 10 seconds when exposed to strong sunlight. They reach their maximum tint in approximately 30 seconds. This rapid response ensures that your eyes are immediately shielded from the intense glare of the sun, effectively reducing discomfort, squinting, and the risk of developing eye fatigue from excessive bright light exposure. When moving indoors or to a shaded area, they fade back to a clear state in around 1 - 2 minutes. Such a quick transition between different lighting conditions makes them highly convenient for daily use, whether you're commuting, engaging in outdoor activities, or simply moving between indoor and outdoor spaces throughout the day.

● Ultimate Durability & Easy Maintenance
Super Hydrophobic: The top layer repels water. Raindrops or splashes bead up and roll off the lens. It also repels oils, grease, and fingerprints. This makes the lenses much easier to keep clean.SHMC includes a hardened layer that protects the lenses from everyday scratches, significantly extending their lifespan.
Easy-to-Clean Surface: The combination of hydrophobic and oleophobic properties means dust, dirt, and smudges have a hard time sticking, and when they do, they wipe off effortlessly.

● Fast Change + Air Blue Coating: You get quick-adjusting sun protection plus enhanced visual clarity and blue light filtering for digital life.Air Blue Coating + SHMC: The superior anti-reflective properties of the Air Blue coating are protected and maintained by the durable, easy-to-clean SHMC top layer. This ensures your vision remains crystal clear for years.

● Adaptive Light Adjustment​
1.56 progressive photogrey green coating lenses feature advanced photochromic technology. In bright sunlight, they can start. This response effectively shields your eyes from intense sunlight and reduces glare, ensuring comfortable vision outdoors. When moving indoors or to a shaded area, they fade back to a clear state. This seamless transition between different lighting conditions eliminates the need to carry separate pairs of regular and sunglasses, providing great convenience for daily activities, whether it's commuting, working, or engaging in outdoor sports

● Progressive Design for Multifocal Vision
The progressive design of these lenses is a major highlight. The upper part of the lens is optimized for clear distance vision. The middle portion offers an intermediate power, which is ideal for tasks such as viewing a computer screen. The lower part is designed for near-vision, making it easy to read books and newspapers. This progressive design allows for a smooth and natural transition between different focal lengths, eliminating the "jump" in vision that is often associated with bifocal or trifocal lenses. Eliminates the need to switch between separate distance and reading glasses, providing a natural, seamless visual experience.

● Cost-Effective Option​
1.56 progressive photogrey green coating lenses present a cost-effective solution for consumers seeking multifunctional lenses.

● Blue Light Blocking
They can effectively block around 45 - 50% of high-energy blue light within the 415 - 455 nm wavelength range. This is highly beneficial for those who spend extended periods in front of digital devices such as computers, tablets, and smartphones. Prolonged exposure to blue light from these sources can lead to various issues, including eye fatigue, dryness, and disruption of the body's natural sleep-wake cycle. By reducing blue light exposure, these lenses help to alleviate digital eye strain and may contribute to better overall eye health in the long run.

● Adaptive Photochromic Function
These lenses feature advanced photochromic technology. In bright sunlight, they can start to darken remarkably fast, usually within a few seconds. They reach their maximum tint in a short time, providing immediate protection against the intense glare of the sun. When moving indoors or to a shaded area, they fade back to a clear state in a short period. This seamless transition between different lighting conditions eliminates the need to carry multiple pairs of glasses, making them extremely convenient for daily use

● SHMC Technology​
The SHMC technology further elevates the performance of these lenses. The super-hydrophobic aspect of the coating repels water, oil, and dust particles. This means that water droplets from rain or splashes, as well as greasy substances, will not easily adhere to the lens surface. As a result, the lenses stay cleaner for longer, maintaining their optical clarity. Additionally, the multifunctional nature of the SHMC coating contributes to the overall durability of the lenses.

● Spin coating is a thin film preparation technology that can realize uniform coating of materials on the substrate surface by high-speed rotation.

● The spin coating technique places the color-change film on the surface of the lens, so the color only changes on the surface of the lens.

● The color changes faster, the color is deeper, and the fading is more uniform.

● Owing to its rapid and uniform photochromic properties, spin coating helps the lens better adapt to changes in ambient light, reducing visual discrepancies and providing a more comfortable and natural visual experience.

● 1.67 Refractive Index - Lighter, Thinner & More Comfortable. High refractive index lenses can be made thinner and lighter, making them more comfortable to wear and more aesthetically pleasing. It can reduce the thickness of the edge of the lens, making the overall appearance of the glasses more fashionable.  For people with high myopia, high refractive power lenses are a good choice because they can provide sufficient correction effect while maintaining the thinness and lightness of the lens.
