1.56 Flat Top HMC Bifocal Finished Lens

1. Bifocal Design    
The upper part of the lens is the distance vision zone (for viewing distant objects), and the lower part is the near vision zone (for viewing close-up objects). It adopts a flat-top bifocal design—the upper edge of the near vision zone is a horizontal straight line. Compared with round-top bifocals, this design allows wearers to access the near vision field more quickly when looking downward. Additionally, the dividing line is relatively less obvious, resulting in a more natural appearance.    
    
2. Material Advantages    
Made of resin material, the lens features light weight and strong impact resistance, ensuring more comfortable and safe wearing—ideal for long-term daily use. Compared with glass lenses, resin lenses are less likely to break, providing better protection for the eyes against accidental injuries.
