Abstract
A method for interactive adjustment of a parameter of a continuously variable optical lens involving having a subject view an eye chart through a variable lens frame comprising at least one continuously variable optical lens, applying a modulation to a selected parameter of said continuously variable optical lens around an average value, and tuning said average value by minimizing the flickering visible to the subject and due to the modulation.
