Claim 0:
1. An adjustable lens configured to be worn in front of a user's eye, comprising:
an electrically modulated optical material interposed between first and second transparent substrates;
a common electrode on the first substrate;
an array of patterned electrodes on the second substrate that adjust a phase profile of the electrically modulated optical material;
an array of variable-resistance conductive paths that are each coupled to a respective subset of the patterned electrodes;
a switch coupled between two of the variable-resistance conductive paths in the array of variable-resistance conductive paths; and
digital voltage selection circuitry that selects an analog voltage from a predetermined set of voltages that are generated off of the adjustable lens and that provides the selected analog voltage to a respective one of the variable-resistance conductive paths.
