Abstract
A portable display system operative to present images to a user wearing the display and to correct vision using adaptive optics may include a lens system with a variable index of refraction and an image projector and image capture device. The image projector may project a pattern onto a retina of the user'"'"'s eye(s) and the image capture device may capture a retinal reflection image of the pattern. A processor may compare the retinal reflection image with a model to determine deviation from the model. One or more different wavelengths of light may be used for the projected pattern, such as one or more of Infrared (Ir), Red, Green, Blue or White wavelengths generated by discrete and/or integrated light sources (e.g., W, R, B, G, Ir LED'"'"'s and/or W, R, B, G, Ir LASERS) that may also comprise a light source for the image projector.
