Abstract: A four-axis asymmetric orthokeratology lens includes a base curve zone, and a reverse curve zone, an adaptation curve zone, and a peripheral curve zone that are successively formed outward from a periphery of the base curve zone. A center of a circle of the base curve zone corresponds to a center of a cornea, and a zone, corresponding to the adaptation curve zone, of the cornea is defined as a specific annular zone. According to the four-axis asymmetric orthokeratology lens, four meridional lines of a lens body are determined based on a mean sagittal depth in the specific annular zone on the cornea. The four meridional lines divide the adaptation curve zone of the lens body into the four sector ring zones, and different curvatures are specifically set for each meridional line, to relatively independently design curvatures for curved surfaces of the four sector ring zones.

Abstract: A computing system performs balanced power management based on requirements of graphics scenes in a video game. Based on the requirements of the graphics scenes, the system selects one or more performance metrics to reduce in real-time, where the performance metrics are indicators of video game quality. The system compares estimated power consumption with a power budget after reducing the one or more performance metrics. Based on the requirements of the graphics scenes, the system further selects one or more quality enhancers to activate in real-time while keeping the estimated power consumption within the power budget. Each quality enhancer enhances the video game with respect to a performance metric. The system then displays the video game enhanced by the one or more quality enhancers.
