description In illustrative implementations of this invention, a lensometer includes a small aperture camera for capturing an image of light that travels from a display surface, through a subject lens and to the camera. One or more computers are programmed to perform calculations that take the image as an input and that compute, for each respective region in a set of regions of the subject lens, a refractive attribute of the respective region.
