Abstract
A hybrid lens is disclosed including optically coupled varifocal lens and adaptive lens. The varifocal lens is configured for varying optical power of the hybrid lens, and an adaptive lens includes a voltage-controlled element for varying optical power of the adaptive lens in coordination with varying the optical power of the varifocal lens and responsive to variation of the optical power of the hybrid lens, for lessening an optical aberration of the hybrid lens. The hybrid lens may be used in head-mounted displays e.g. for lessening a vergence-accommodation conflict.
