What type of lens design places near power in the center?

The type of lens design that places near power in the center is known as a concentric design. Concentric designs feature rings of differing optical powers, with the near vision zone typically positioned in the center. This innovative approach allows the wearer to focus on near objects without needing to shift their gaze significantly, providing ease of use and comfort for tasks that require close vision, such as reading.

Monovision design, which typically provides one lens for distance vision and another for near, places the near power in one eye rather than at the center of the lens. Segment bifocal lenses have a distinct segment at the bottom for near vision but do not place the near power in the center. Soft designs generally refer to contact lenses that may provide a gradual transition for vision but do not specifically place near power in the center like a concentric lens. Thus, concentric design stands out for its specific arrangement of powers.
