1.56 Blue Block Photogrey Progressive Airblue Coating SHMC Finished Lens

1. Functional Features    
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.    
Photochromic Function: Adopting photochromic technology, the lens gradually darkens within 1-2 minutes when exposed to ultraviolet (UV) light, blocking approximately 80% of sunlight. When returned indoors, it reverts to transparency within 3-5 minutes.    
Progressive Multifocal Design: The power on the lens surface gradually transitions from the distance vision zone to the near vision zone. This design delivers clear vision correction for far, intermediate, and near distances, eliminating the "image jump" phenomenon common in bifocal and trifocal lenses and ensuring smooth visual transition.

2. Material & Coating Advantages    
Material: The lens is made of resin, which offers advantages such as light weight and excellent impact resistance, ensuring more comfortable and safe wearing.    
Coating:    
SHMC (Super Hard Multi-Coating): Boasts high hardness and wear resistance, effectively resisting scratches and extending the lens service life.    
Airblue Coating (Green Anti-Reflective AR Coating): Reduces light reflection on the lens surface, improves light transmittance for clearer vision, and enhances the lens’s aesthetic appeal.
