Eyeglasses which comprise a pair of optical plates for each eye. Each of the optical plates is made up of a front plate and a rear plate and a return and hinge mechanism links the optical plates of each pair with one another. An adjustment mechanism facilitates relative movement of the optical plates, of each pair, in a plane substantially perpendicular to a viewing direction of the eyeglasses. The return and hinge mechanism and the adjustment mechanism are decoupled.
