Abstract
Methods are disclosed comprising measuring, with a first scanner, a central part of the visual image, measuring, with a second scanner, a peripheral part of the visual image, calculating, by a processor, a pan-retinal measure of image contrast for an extended area of the retina, and optimizing a pan-retinal visual quality. Methods further comprising optimizing a pan-retinal visual quality are also disclosed. Systems are also disclosed comprising either a scanner or a laser, a non-transitory memory having instructions that, in response to an execution by a processor, the processor receives a first measurement of the central part of the visual image, receives a second measurement of the peripheral part of the visual image, and calculates a pan-retinal measure of image contrast for an extended area of the retina. Methods of manufacturing lenses, including contact lenses are disclosed.
