1.56 Blue Block Progressive Finished Lens

1. Blue Light & UV Protection    
This lens effectively blocks blue light below 420nm and provides 100% protection against both UV-A and UV-B rays. It reduces blue light-induced eye damage, making it suitable for people who use electronic devices for extended periods or are frequently exposed to sunlight.    
    
2. Progressive Multifocal Design    
The lens features multiple focal points, with power gradually transitioning from the distance vision zone to the near vision zone. It delivers clear vision correction for far, intermediate, and near distances, eliminating the "image jump" issue common in bifocal and trifocal lenses. This design ensures smooth visual transition and also offers a more aesthetically pleasing appearance.    
    
3. Material & Coating Advantages    
Material: Most lenses are made of imported resin, which boasts excellent optical and physical properties. It is lightweight, ensuring comfortable wearing.    
Coating: Coatings such as HMC (Hard Multi-Coating) enhance lens hardness to reduce scratches, while also improving light transmittance for clearer vision.    
    
4. Suitable Crowds    
Ideal for people with myopia, hyperopia, or presbyopia who need to frequently switch between far and near vision—such as office workers, teachers, and middle-aged/elderly individuals. It not only meets their daily vision needs at different distances but also protects the eyes from blue light and UV ray damage.
