Consumers have no trouble finding the names of manufacturers or brand logos on the frames of their glasses. Lenses, on the other hand, do not have logos that are instantly visible. Or do they? In fact, all ZEISS branded lenses have a Z on the glass to identify them as genuine ZEISS products.
ZEISS lenses have to pass extremely tough inspections to ensure they comply with all Carl Zeiss standards before they even leave our production sites. Consequently, we feel that every ZEISS branded lens should be identified by its trademark so that you, the patient, and your optometrist, can distinguish it from other lenses.
We laser-engrave a tiny Z into all ZEISS branded lenses before they leave our laboratories. The Z icon is engraved into the surface of the lens. The entire process is touchless and places the logo into a precisely defined location. The laser operates at a wavelength that ensures that the engraving is semi-transparent so it will not interfere with the wearer’s vision. The ZEISS quality seal is visible only when you look at the lens, not when you look through it.
On bifocal, trifocal and progressive lenses, the ZEISS laser engraving is placed in a position where it can still be easily identified once the glasses have been fitted into the frame by the optometrist. However, during the cutting process performed on single strength lenses, the required centering and cutting of the lens may make the logo disappear once the lens has been dimensioned to fit the frame after the edging work is complete and you may no longer be able to see it. However, there is no need for concern. You can count on the fact that your eye care professional has chosen ZEISS lenses. To make certain, he or she will give you an authenticity card that guarantees that your glasses are fitted with ZEISS lenses.
The subtly-engraved ZEISS logo on your brand name lenses guarantees that you will enjoy optimal vision comfort. This state-of-the-art quality is achieved thanks to three unique technologies:
For those of you who would like to know specifically what makes our lenses so different, we have provided an overview below:

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.
