1.56 Progressive Photogrey Green Coating Finished Lens

1. Functional Features    
Photochromic Function: The lens contains photochromic molecules (e.g., naphthopyran-based organic molecules). When exposed to ultraviolet (UV) light, the lens darkens quickly to block intense light; after returning indoors, it reverts to transparency rapidly. This allows adaptation to different light environments and reduces eye fatigue.    
Progressive Multifocal Design: The lens power gradually transitions from the distance vision zone to the near vision zone, providing clear vision correction for far, intermediate, and near distances. It eliminates the "image jump" phenomenon and ensures smooth visual transition, making it suitable for middle-aged and elderly people, as well as those who need to frequently switch between far and near vision.    
    
2. Advantages of Green Coating    
Green coatings are typically HMC (Hard Multi-Coating) or SHMC (Super Hard Multi-Coating):    
HMC Coating: Reduces light reflection on the lens surface, improves light transmittance for clearer vision, and enhances the lens’s wear resistance.    
SHMC Coating: Based on the properties of HMC, it further features water repellency, oil repellency, and anti-static properties, making the lens easier to clean and maintain.    
    
3. Material Advantages    
Most lenses are made of imported resin, which offers excellent optical performance, a high Abbe number, and superior imaging quality. Additionally, it is lightweight and highly impact-resistant, ensuring comfortable and safe wearing.
