Measuring machine for lens mapping

A machine for measuring the optical properties of a lens for a pair of eyeglasses includes a light emitting system for emitting a light beam; a receiver arranged for receiving the light beam; an alignment system configured to align the lens according to a predetermined measuring position; a gripping system configured to grip the eyeglasses; and a supporting system on which the eyeglasses or the single lens are positioned. The alignment system is arranged at a distance from the light emitting system so that at least a lower support element is not intercepted by the light beam. The gripping system is in a closed configuration after the alignment has been performed and then a subsequent shifting of the support structure is carried out to bring the lens under the light emitting system.
