1. A method for adjusting optical power of a hybrid lens for collimating image light, the hybrid lens comprising a varifocal lens optically coupled to an adaptive lens, the method comprising:
varying optical power of the varifocal and adaptive lenses in coordination with one another based on a pre-determined mutual variation of optical power for lessening an off-axis aberration of the hybrid lens with respect to the image light for each sub-range of a pre-defined set of sub-ranges of optical powers of the hybrid lens with respect to the image light.
