Patent ID: 8777408

Claim:
Variable Focus Spectacles comprising: a first pair of lenses, each having a predetermined optical power, each disposed substantially perpendicularly to corresponding left and right optical axes of the variable focus spectacles; a pair of membrane support structures, each having an opening therein, each of said membrane support structures being associated with and mounted adjacent to and within the field of view of one of said first pair of lenses; an adjustable connector connecting each of said first lenses to its associated membrane support structure, each said adjustable connector allowing angular motion between its respective first lens and its associated membrane support structure while a connecting distance is held constant, the connecting distance being defined as a distance between a location where the adjustable connector contacts the respective first lens and a location where the adjustable connector contacts the associated membrane support structure, the connecting distance being in a direction substantially parallel to the corresponding optical axis, the adjustable connector further allowing adjustment of the connecting distance; a transparent membrane attached to each of said membrane support structures across said openings; a flexible seal extending between each of said first lenses and its associated membrane support structure, said flexible seals permitting motion between said first lenses and their associated membrane support structures; and liquid having a predetermined index of refraction substantially filling the spaces between each of said first pair of lenses and its associated membrane support structure within its respective seal.
