Abstract: The present invention relates to a lens for eye-tracking applications. The lens comprises a first protective layer, arranged to face towards the eye to be tracked when the lens is used for eye-tracking. It also comprises at least one light source, at least partly arranged in the first protective layer, arranged to emit a first light from the first protective layer in a direction towards the eye. Moreover, it comprises at least one image capturing device, at least partly arranged in the first protective layer, arranged to receive the first light within the first protective layer. The lens further comprises an absorptive layer, arranged on the far side of the first protective layer seen from the eye to be tracked when the lens is used for eye-tracking, adapted to be absorptive for wavelengths of the majority of the first light.

Abstract: A method for mounting functional elements in a lens includes mounting the functional elements on a foil, applying a closed contour alignment surface of an alignment tool having a central opening surrounded by the closed contour on the foil portion opposite to the mounted function elements, applying underpressure on the central opening to maintain the foil portion with the mounted functional elements on the alignment tool, cutting a flap including the foil portion and supporting the functional elements out of the foil, positioning and aligning the flap through actuator, fixing the position of the flap against the adjacent foil surface, embedding the foil with the mounted functional elements in a predetermined distance to the front surface of a mould, and casting and curing the lens with the embedded foil.

Abstract: A lens for eye tracking applications is described. The lens comprises a first protective layer with a first surface, arranged to face towards the eye to be tracked when the lens is used for eye tracking. The lens is characterized in that the lens further comprises a supporting layer and a second protective layer with a second surface, arranged to face away from the eye to be tracked when the lens is used for eye tracking. The supporting layer is arranged between the first protective layer and the second protective layer, and the supporting layer comprises at least a first opening between the first protective layer and the second protective layer. At least one electrical component arranged extending through the first opening.
