Abstract:
1. A method for fitting a lens, the method comprising: obtaining an image of the lens with an imaging device; identifying an edge of the lens on an eye in the image; implementing a policy in a processor for identifying a number of zones, a size of the number of zones, and a shape of the number of zones in the lens, each zone in the number of zones defined by physical markings on the lens; marking the lens with the physical markings to indicate a location of each zone in the number of zones, the physical markings including a cross pattern; identifying and applying the plurality of zones with a digital imaging device based on the physical markings on the lens; associating the number of zones with the image of the lens based on the edge of the lens; identifying a value for each zone in the number of zones based on a brightness of a substance located between the lens and the eye, wherein the brightness is greater as the distance is greater between the lens and the eye, and wherein the brightness corresponds to an amount of substance in each zone; generating a graph to indicate the intensities substantially at each location in the cross pattern zone; and designing a new lens based on the value in each zone to reach a desired value in each zone.
