    Abstract: A visual simulator designs a spectacle lens based on acquired lens design data. Original image data representing an image viewed through the lens and frame data including shape data and layout information of a spectacle frame to which the spectacle lens is fitted are acquired. Image data is generated from the original image data and frame data and displayed on a screen. In an entire display mode, a visual field based on the shape data is entirely displayed on the screen. In a partial display mode, a part of the visual field determined by a distance from the spectacle wearer to the screen and a dimension of the screen is displayed.
