  • Adjustable progressive lens and design method
    Patent number: 11086144
    Abstract: An adjustable spectacle lens has a first lens element and a second lens element arranged one behind the other along an optical axis of the lens. The first and second lens element are configured to vary their combined optical properties when moved relative to each other in a direction transverse to the optical axis. The adjustable lens element is an adjustable progressive lens element. The first and second lens element are configured to vary at least one of a size and a power of the near, the distance, and the intermediate portion relative to each other, when the first lens element and the second lens element are moved relative to each other in the direction transverse to the optical axis. The first and second lens elements can be configured to conjointly provide a near, a distance and an intermediate portion that can be changed depending on the visual task.
