Where is the ZEISS engraving on a lens?

It is a tiny, discreet laser-engraved mark near the edge of the lens. On progressive lenses it is positioned so that it can still be found after the lenses are fitted into the frame. Hold the lens against a dark background under light and tilt it slightly to see it.

What if I cannot find the engraving?

The engraving can be removed when lenses are cut, edged and fitted. If you cannot see it, ask your optician for the ZEISS authenticity or warranty certificate.

Is there a warranty on ZEISS lenses?

ZEISS states a manufacturer's warranty of 24 months on its lenses and, for some progressive lenses, an additional adaptation period in the first three months. The exact terms in Nepal depend on your optician, so ask for them in writing.

Can I choose to have the engraving left off?

ZEISS says customers who do not want the engraving can tell the optician when ordering. In that case, keep the certificate and invoice as your proof of purchase.

What should my invoice say?

It should name the exact lens design, material or index and coating, for example the product family and the DuraVision coating, not just the word ZEISS.

How to Spot Genuine ZEISS Lenses: Engraving and Warranty

Genuine ZEISS lenses carry a small laser engraving of the ZEISS mark. Because edging and fitting can remove it, ask your optician for the authenticity or warranty certificate and make sure the exact lens name is written on your invoice. Vague labels like 'German lens' with no product name are a warning sign.

How to Spot Genuine ZEISS Lenses: Engraving and Warranty

Quick answer

Genuine ZEISS lenses carry a small laser engraving of the ZEISS mark. If it is missing or has been polished away during fitting, ask your optician for the ZEISS authenticity or warranty certificate and check that the exact lens name appears on your invoice.

A brand name is only worth paying for if you actually receive the product. Here is a practical way to check that the lenses in your new glasses are the ones you paid for.

1. Look for the laser engraving

ZEISS marks its branded lenses with a very small laser engraving before they leave its laboratories. It is intentionally discreet, so you will not see it with a casual glance. Hold your glasses against a dark background under good light, tilt the lens slowly and look near the edge. On progressive lenses the mark is placed where it can still be found after fitting.

2. Why the engraving can be missing

The mark is very shallow. When a lens is cut, edged and fitted into a frame, the engraving can be removed. That does not automatically mean the lens is fake, but it does mean you need another form of proof. ZEISS also notes that customers can ask for their lenses not to be engraved.

3. Ask for the certificate

ZEISS recommends asking your optician for the authenticity or warranty certificate that confirms your lenses are genuine ZEISS. A professional optician should provide it without fuss. Keep it with your invoice.

4. Check what your invoice says

Many lens families share the ZEISS name, so 'ZEISS lens' on a receipt is not specific enough. A good invoice states the lens type and design, the material or index, and the coating. If you are told you are getting premium lenses, you should be able to read the product name in writing.

5. Understand the warranty

ZEISS states a manufacturer's warranty of 24 months, and its guidance for precision progressive lenses includes an additional adaptation period in the first three months. These terms are set out by ZEISS internationally. How they apply to you in Nepal depends on your supplier, so ask for the warranty in writing before you pay.

Quick checklist before you pay

Ask which exact ZEISS lens design and coating you are getting.
Ask to see the engraving, or ask how authenticity will be confirmed.
Get the certificate and a detailed invoice.
Ask who handles warranty claims and how long it takes.
