Progressive-Power Lens Selector, Progressive Power Lens Selection Method, and Non-Transitory Computer Readable Storage Medium Storing A Progressive-Power Lens Selection Program

摘要

An accommodation ability acquisition unit, a near vision prescription range acquisition unit, a lens database storing design parameters of progressive-power lenses in response to addition power with respect to each of plural types, an accommodation ability computation unit computing used accommodation ability for near vision, a necessary addition power computation unit computing necessary addition power for near vision, a range computation unit computing the maximum distance ranges and the maximum near ranges when lenses are worn based on the necessary addition power in lenses selected as lenses having design elements of a set condition equal to or more than the necessary addition power of the plural types stored in the lens database, and an output control unit allowing a display device to display the maximum distance ranges and the maximum near ranges with respect to the lenses of the design types selected by a selecting unit in juxtaposition are provided.
