Abstract:
A method for designing an eyeglass lens includes: a basic value calculation step of determining a basic visualizing action index representing a visualizing action taken when a person who wears no eyeglasses or single-vision lenses looks at an object; a progressive value calculation step of determining a progressive visualizing action index representing a visualizing action taken when the person who wears reference progressive addition lenses looks at the object; and a lens designing step of enlarging the field of view as compared with that of the reference progressive addition lenses when the progressive visualizing action index shows greater head movement than the basic visualizing action index does, whereas enlarging an aberration region as compared with that of the reference progressive addition lenses when the progressive visualizing action index shows smaller head movement than the basic visualizing action index does.
