Abstract: A multifocal contact lens having concentric bands of different lens curves, wherein a plurality of curves for farsightedness alternate with a plurality of curves for nearsightedness. A mold for the lens and a production method thereof are also provided. Farsight curve surfaces (F1, F2, ...) of the lens curve (2) have centers of curvature (OF1, OF2, ...) on the optical axis, and radiuses of curvature (RF1, RF2, ...) set so that rays of light incident into farsight curve surfaces and parallel to the optical axis form an image effectively at a single farsight focus on the optical axis. Nearsight curve surfaces (N1, N2, ...) of the lens curve have centers of curvature (ON1, ON2, ...) on the optical axis, and radiuses of curvature (RN1, RN2, ...) set so that rays of light incident into nearsight curve surfaces and parallel to the optical axis form an image effectively at a single nearsight focus (FN) on the optical axis.

Abstract: An environment-adapted image display system by which an image is corrected in a shorter time, an image processing method, and an information storage medium are disclosed. Visual environment information is collected by a chromatic light sensor (60) and the output is converted to a color signal (Y3, x3, y3) by a Y3x3y3 conversion section (143). The Y value of the color signal (Y3, x3, y3) is replaced with Y1 which is the Y value of an ideal environment by a Y replacement section (142). The color difference between the color signal (Y1, x3, y3) after the replacement and the ideal color signal (Y1, x1, y1) is calculated by a color difference calculating section (145). If the color difference is out of an allowable correction range, the color difference is corrected by an environment subject coefficient correcting section (148). Information for image display is corrected by using the corrected color difference (Δx', Δy').
