An accessory for improving the accuracy, and/or facilitating the use, and/or improving aesthetics and/or ergonomics of digitizer cursors is disclosed. The accessory mounts an optical element to the position-sighting aperture on the cursor. In all embodiments, the accessory or accessories may be completely and easily removed from the cursor (and replaced). Optical elements may be interchanged and combined so as to permit the operator to select optics that are most efficient for a particular digitizer task. In particular embodiments, the lens is mounted directly to the position-sighting aperture or to another member which is directly mounted to the position sighting aperture. In some embodiments, the optical element is pivotally mounted so that it can be moved into and out of the operator's line of sight. This allows the operator to move the optical element out of his line of sight to the position-sighting aperture without removing the optical element from the cursor.
