ABSTRACT:
This invention relates to variable focus eyeglasses comprising flexible and rigid optical components. The rigid components act as molds which modify the optical properties of the flexible components when the flexible and rigid components are engaged.
At least one of the flexible or rigid components is movable along an anterior-posterior axis, resulting in the distortion and restitution of a flexible component by one or more rigid components thereby altering the optical properties of the system.
A spring mechanism located in the nosepiece or bridge portion of the eyeglasses may be used to facilitate the anterior-posterior movement of the movable components.
