Abstract
A pair of eyeglasses may include one or more adjustable lenses. An adjustable lens may include a stack of liquid crystal cells with passive matrix electrode arrays. Each passive matrix electrode array may include a pair of orthogonal electrodes that are rotated relative to other pairs of orthogonal electrodes in the stack. Control circuitry may apply different voltage profiles to the passive matrix electrode arrays to create the desired lens characteristics in the adjustable lens. The voltage profiles may be based on a stored look-up table that maps different target lens characteristics to different voltage profiles for the passive matrix electrode arrays. The target lens characteristics may include at least one of a target lens power and a target optical aberration correction. The look-up table may be based on information gathered during design and manufacturing using numerical optimization techniques.
