Abstract: An eyeglass lens having a power of from about a minus 0.12 to about minus 1.00 diopters (and preferably minus 0.50 diopters) that is particularly beneficial and improves vision of a user under night or other low-light conditions. The lens may be incorporated in a pair of eyeglass frames and may be used by users without corrective eyewear or in a pair of clip-on” frames for use by a user already requiring corrective eyewear.

Abstract: In computer image generation (CIG) systems, image data for defining pixel modulation values and for supporting a display having a predetermined resolution are determined for defining a scene. For some applications, such as for representing background and/or peripheral areas, it may be acceptable to use data having a lower resolution than the predetermined resolution. Method and apparatus for taking a portion of the image data obtain derived data by a predetermined combination of the portion of image data. Lines of composed data supplied to a display device include a sequence of pixel modulation values selected from the portion of image data and the derived data. In one embodiment the number of lines supported by the image data is doubled with each line containing 50% image data and 50% derived data. Pixel modulation values may be oversampled between adjacent lines of the display for obtaining derived data.
