Spectacle lenses as thick as glass blocks – fortunately, those times are long gone. Progress is also remarkable in the field of optics thanks to a computer-assisted process called OPTIMA. This process makes it possible to reduce the visible edge and centre thickness of spectacle lenses to a technically feasible minimum.
The great news: With OPTIMA spectacle lenses can often be made much thinner because they are precisely calculated to the shape of the selected spectacle frame.
The key benefit of centre thickness optimisation: The spectacle lens is ground thinner over the entire rear surface. Of course this is done without any modification of the dioptric or prismatic effect. Such lenses differ from traditional spectacle lenses in important area: Instead of being manufactured round like a tube, they are approximated to the shape of the final spectacle lens. This makes it possible to grind the lenses as thick or as thin as needed for glazing.
The following factors play an important role:
OPTIMA is therefore a great solution if a thickness reduction of at least 0.5 mm is reached with the frame and centring data provided. For each OPTIMA order, the OPTIMA customer service first determines whether this objective can be attained.
