摘要：
The invention relates to a method and a head mounted eye tracking device (10a, 10b) for determining at least a feature of an eye (12), wherein the eye tracking device (10a, 10b) comprises a capturing device (C) for capturing light reflected by the eye (12) and an optical component (14； E, E1, En, E2) capable of altering a propagation direction of the light passing through the optical component (14； E, E1, En, E2). The eye tracking device (10a, 10b) is configured such that when fixed to the head of the user the light captured by the capturing device (C) has passed through the optical component (14； E, E1, En, E2) and constitutes at least part of an image and the feature is determined on the basis of the image in dependency of an information about a relative position between the eye (12) and the head mounted eye tracking device (10a, 10b).
