  1. How Vzun Progressive Lenses Work? A progressive lens has three sections. Unlike bifocal and trifocal glasses, there is no visible line that separates the sections. With progressive lenses, you look through the top section of the lens to see things that are far away. The middle section of the lenses clarifies objects in the middle ground. The bottom section helps you see objects that are close up. Progressive lenses change slightly in prescription throughout the lens. This makes for a smooth, gradual shift instead of a harsh difference in section.
