Abstract

The apparatus comprises a transparent screen (15) which picks up the image that an optical unit (27, 28) forms of the ophthalmic lens (26) to be centered and blocked. The screen image is picked up by a video camera (14) and transmitted to a monitor where it is superimposed on the already corrected image received by the monitor of the frame ring to which the lens (26) is to be mounted. An angular movement of the screen (15) and camera (14) is accompanied by an angular movement and by a downward movement of an intermediate arm (17) carrying a member (19) which is adhered to the ophthalmic lens (26).
