A display system comprising: a wavefront generator comprising: a manipulable display configurable to produce a modified raster image having a plurality of pixels; a lenslet array in a projection path from the manipulable display so that the modified raster image is projected by the lenslet array from the manipulable display toward a location such that each of the plurality of pixels of the modified raster image produced by the manipulable display are imaged onto a region of a retina of a user's and/or patient's eye such that an aggregate of imaged dots, corresponding to the plurality of pixels, forms a corresponding raster image on the region of the retina of the user's and/or patient's eye ; and a processor configured: to receive an indicator defining an optical aberration of the user's and/or patient's eye ; and to control the manipulable display so that the modified raster image of the manipulable display is modified from a desired raster image per the optical aberration of the user's and/or patient's eye so that the optical aberrations of the user's and/or patient's eye alter the modified raster image toward the desired raster image when forming the raster image on the retina, wherein the modified raster image is modified from the desired raster image in response to characteristics of the lenslet array, wherein the desired raster image comprises a complex image so that a plurality of lenslets of the array each project an associated two-dimensional modified image portion. a manipulable display configurable to produce a modified raster image having a plurality of pixels; a lenslet array in a projection path from the manipulable display so that the modified raster image is projected by the lenslet array from the manipulable display toward a location such that each of the plurality of pixels of the modified raster image produced by the manipulable display are imaged onto a region of a retina of a user's and/or patient's eye such that an aggregate of imaged dots, corresponding to the plurality of pixels, forms a corresponding raster image on the region of the retina of the user's and/or patient's eye ; and a processor configured: to receive an indicator defining an optical aberration of the user's and/or patient's eye ; and to control the manipulable display so that the modified raster image of the manipulable display is modified from a desired raster image per the optical aberration of the user's and/or patient's eye so that the optical aberrations of the user's and/or patient's eye alter the modified raster image toward the desired raster image when forming the raster image on the retina, to receive an indicator defining an optical aberration of the user's and/or patient's eye ; and to control the manipulable display so that the modified raster image of the manipulable display is modified from a desired raster image per the optical aberration of the user's and/or patient's eye so that the optical aberrations of the user's and/or patient's eye alter the modified raster image toward the desired raster image when forming the raster image on the retina, wherein the modified raster image is modified from the desired raster image in response to characteristics of the lenslet array, wherein the desired raster image comprises a complex image so that a plurality of lenslets of the array each project an associated two-dimensional modified image portion. <EOS>
