Progressive lenses laser engravings and markings pdf catalogue

All progressive lenses, whoever the manufacturer (Essilor, Zeiss, Sola, Hoya,…), are engraved. These micro-engravings are done with a laser and are very fine and mostly unnoticeable when you wear your glasses.

They are essential for several reasons:

– They enable the optician to identify the optical centre of the lens, and to adjust and centre your lenses very precisely in front of your eyes.

– They also make it possible to establish the origin of the lenses (manufacturer, model, materials and degree of presbyopia).

In most cases, patient eyes adapt to the presence of micro-engravings since they are located on the edge of his field of vision. If a feeling of discomfort exists, it usually disappears after a few hours of use.
The engravings are not always easy to find, especially if lenses have an anti-reflective coating, are tinted, or are older or scratched, especially so for presbyopes or inexperienced persons.
