Thanks to the use of latest technology generators, which work with a precision of 0.3 microns, this lens has the ability to offer a more precise vision in all areas needed, and to compensate for any second level errors. Thus, you get a large area close up, and a sharper intermediate zone by adjusting the actual dioptric measurement that of the prescription more consistently. The lens, which follows all the modern aesthetic standards of internal base flattening, has a variable inset construction, and offers the possibility of modifying the progression channel for each eye. It is, in fact, possible to personalize even further: the morphological and functional differences between right and left handed users. The Progressive Aurora Clear lenses are supplied in two basic designs that cover the most common uses: - Ottima, which ensures maximum amplitude of distant vision, especially peripheral, and is ideal for those who spend most of the day outdoors. - Ampia, which offers a comfortable solution for all situations. To these designs, we have also added Unica, designed to meet the specific needs of the customer through the optimization of specific parameters provided: right or left handed, pantoscopic tilt of the frame, corneal apex / lens distance, angle of winding of the frame and reading distance. All of these factors make it a custom-built lens, specifically for each customer. To the classic progressive geometries, we add the Degressive INDOOR (PC & MEETING) geometries, specially designed to provide all the comfort of aurora technology even to those who spend most of the time in closed in spaces, or simply need a pair of glasses optimized for close - intermediate vision.
