Eyeglass lenses as thick as glass blocks – fortunately, those days are long gone. Progress is also remarkable in the field of optics thanks to a computer-assisted process. This process makes it possible to reduce the visible edge and center thickness of eyeglass lenses to a technically feasible minimum.
The great news: Thanks to computer-assisted production, eyeglass lenses can often be made much thinner because they are precisely calculated to the shape of the eyeglass frames selected.
The key benefit of center thickness optimization: The eyeglass 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 eyeglass lenses in one important area: Instead of being manufactured round like a tube, they are approximated to the shape of the final eyeglass 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:
Computer-assisted design is therefore a great solution if a thickness reduction of at least 0.5 mm is reached with the frame and centering data provided. For each order, customer service first determines whether this objective can be attained.
Contact lenses are a very good alternative to glasses – yet there are still a few vision solutions that are only possible with good ol' glasses.
