Abstract
An image of an eye of a user can be received from an image sensor, the image resulting from the image sensor detecting light from one or more illuminators reflected from the eye of the user and reflected from optic arrangements located between the one or more illuminators and the eye of the user, wherein the optic arrangements comprise features having a known pattern. Glints are identified in the image, wherein a glint is a representation in the image of a reflection of light from a cornea of the eye of the user and/or from a feature of the optic arrangements. Relative positions in the image of the identified glints are determined, and on condition that the relative positions conform with the known pattern, at least one glint of the identified glints is identified as a representation in the image of a reflection from a feature of the optic arrangements.
