Geometric phase lens alignment in an augmented reality head mounted display

A head-mounted display comprises:

• a display block configured to combine light from a local area with image light to form an augmented scene, and provide the augmented scene to an eyebox corresponding a location of a user's eye, the display block comprising:
• a waveguide display configured to emit the image light,
• a focusing assembly having a first optical power, the focusing assembly configured to present the augmented scene at a first focal distance, wherein the focusing assembly includes a plurality of focusing geometric phase lenses, each focusing geometric phase lens having a respective axis of orientation, and
• a compensation assembly having a second optical power that compensates for the first optical power, and the compensation assembly includes a plurality of compensation geometric phase lenses, each compensation geometric phase lens having a respective corresponding focusing geometric phase lens of the plurality of focusing geometric phases lenses, and each compensation geometric phase lens having a respective axis of orientation that is orthogonal to the axis of orientation of a corresponding focusing geometric phase lens.
