An eye tracking system comprising a processor configured to: receive a plurality of images of an eye from a camera, each image comprising an illuminated sub-region of a cornea of the eye, the illuminated sub-region comprising: a first corneal reflection of a first light source from a surface of the illuminated sub-region; and a second corneal reflection of a second light source from the surface of the illuminated sub-region; for each image, determine a three-dimensional, 3D, position of the first corneal reflection and a 3D position of the second corneal reflection based on a position of the camera, a position of the first light source, a position of the second light source, positions of the first and second corneal reflections in the image and a corneal surface model for the illuminated sub region; and output a topographical profile of the cornea based on the 3D positions determined for each image.

Eye profiling

An eye tracking device for tracking an eye is described. The eye tracking device comprises: a first diffractive optical element, DOE, arranged in front of the eye, an image module, wherein the image module is configured to capture an image of the eye via the first DOE. The first DOE is adapted to direct a first portion of incident light reflected from the eye, towards the image module. The eye tracking device is characterized in that the first DOE is configured to provide a lens effect.
