The surface of progressive lenses is basically the same as that of ordinary lenses, but they are completely different. It is divided into three visual areas: viewing the distant objects at the top, viewing the nearby objects at the bottom. From top to bottom, it is different lenses, and it can meet the needs of using for distance vision, near vision and various distances in between. There is no need to change the glasses, it is convenient and comfortable.
Visual continuity: It provides a continuous visual experience, eliminating the jarring sensation that occurs when switching between different focal lengths with bifocal lenses. This enables the eyes to smoothly transition when viewing objects at different distances, reducing the risk of visual fatigue.
