Adjustable Progressive Lens and Design Method

An adjustable spectacle lens comprising:

• a first lens element and a second lens element arranged one behind the other along an optical axis of the adjustable spectacle lens;
• wherein the first lens element and the second lens element conjointly define combined optical properties;
• wherein the first lens element and the second lens element are configured to vary the combined optical properties when moved relative to each other in a direction transverse to the optical axis;
• wherein the adjustable spectacle lens is an adjustable progressive spectacle lens, wherein the first lens element and the second lens element are configured to conjointly provide a near portion, a distance portion and an intermediate portion;
• the first lens element and the second lens element being configured to vary at least one of an add power of the near portion, a size of the near portion, a size of the distance portion, and a size of the intermediate portion, when the first lens element and the second lens element are moved relative to each other in a direction transverse to the optical axis.
