Abstract
Abstract Spectacles with adjustable lenses which include a frame with extended arms and bridge, the bridge having gear-track means for holding fast a lens chassis capable of assuming a plurality of positions relative to frame. The lens chassis includes a pair of lenses and a bridge structure supporting said lens, the bridge structure including a shaft having rotatable gears at its extremities for movement along said frame gear-track and in confinement therewith. The lens chassis permits different viewing area of the lens to be exposed when the chassis is moved along said gear-track.
