1. A computer implemented method comprising:
receiving images of an eye through a vision correcting lens via a camera in a head mounted display device;
obtaining an inverse transform corresponding to the vision correcting lens;
applying the inverse transform to the received images to obtain uncorrected images of the eye; and
performing eye tracking based on the uncorrected images of the eye.
