58‐4: Correcting Arbitrary Hybrid Defocus and Astigmatism for Near‐Eye Displays Using Two‐dimensionally Displaced Alvarez Lenses

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 t o 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.
