Description:

This paper proposes an Alvarez lens for vision-correcting near-eye displays. A novel two-dimensional displacement approach with independently controlled direction and distance is proposed to correct arbitrary hybrid defocus and astigmatism. The proposed Alvarez lenses are experimentally verified on an Apple Vision Pro using various combinations of defocus and astigmatism.
