Abstract
Test spectacles for progressive or multifocal ophthalmic lenses, in which the lenses are supported respectively for the two eyes, by means of specially modelled elements suitable for containing even two lenses superimposed and connected to the front-piece composed essentially of two parallel bars in such a way that each lens-holder element can translate independently with respect to the front- piece, appropriately positioning the optical centre of said lens with the optical axis of the corresponding eye of the patient, while positioning with respect to the vertical of said optical centres is given by the nose- piece adjustable in this way, as, in fact, the adjustment or shortening of said nose-piece makes it possible to raise or lower the test glass with respect to the vertical axis of the patient's eye. The diameter of the lenses is such as to permit the use of the optical specifications of said lenses. <IMAGE>
