Vari-lens phoropter and automatic fast focusing infinitely variable focal power lens units precisely matched to varying distances by radar and electronics

A lens system providing an infinitely variable focal power with a combined measuring system reflecting a readout display comprising:

• a first lens and a second lens each having an inner surface and an outer surface, mounted adjacent to each other with said first lens being a forward lens, closer to an object to be viewed, and said second lens being a rearward lens, further from said object to be viewed;
• wherein said first and second lenses inner surfaces are mounted in a juxtaposed relationship with a space formed between said lenses inner surfaces for receiving a transparent fluid medium there between;
• a circular reservoir being substantially C-shaped in cross section to contain the transparent fluid medium between said first and second lenses;
• said circular reservoir and stablilizer rings connected to said first lens and said second lens by an adhesive;
• a set of current connection wires and other components connected to the circular reservoir by said adhesive;
• first and second control members in mechanical communication with said forward and rearward lenses respectively, adapted to translate said lenses in forward and rearward directions;
• a precision gearing system for manipulating said control members;
• an encoder in mechanical communication with said precision gearing system for precision measurement of said lenses;
• and
• a readout device in electrical communication with the encoder and displaying a readout reflecting the movement of said first and second lenses, wherein said precision gearing system comprises
• a first shaft for moving the forward lens, the first shaft consisting of a precision gearing device having a driving pinion gear to drive a gear rack attached to the forward lens which in turn drives the first control member;
• and
• a second shaft for moving the rearward lens, mounted substantially parallel to the first shaft and driven by a reduction set of gears connected to said first shaft, said second shaft having a driving pinion gear to drive a gear rack attached to the rearward lens, which in turn drives the second control member;
• wherein said first and second control members are translated in a predetermined tandem manner by the precision gearing system, so that said first and second lenses are translated according to a predetermined gear ratio thereby.
