Claim Text:
1. An electronically controllable eyewear device, comprising: a cell comprising at least one liquid crystal material capable of changing from a first state of higher light transmittance when no voltage is applied to a second state of a lower light transmittance upon application of a voltage and vice versa; a photosensor associated with the cell, said photosensor generating an input signal based on ambient light level to operate said device in an auto mode; a single switch capable of being actuated in a series of predetermined sequences to generate a switch signal; and a control circuit capable of receiving said input signal said switch signal and being capable of generating a separate output signal to operate said cell wherein in said auto mode detection of an ambient light level above a predetermined threshold value results in said voltage being applied, and wherein detection of an ambient light level below said predetermined threshold value results in no voltage being applied; wherein actuation of said single switch in a first predetermined sequence enables (i) a state change of the liquid crystal material between said first and second states; wherein actuation of said single switch in a second predetermined sequence enables (ii) a system change from a manual mode to said auto mode; and wherein actuation of said single switch in a third predetermined sequence enables (iii) a change in said predetermined threshold value.
