Laser engravings are extremely small, faint markings etched onto the surface of an eyeglass lens by a laser. They do not affect vision but serve as invisible reference points for opticians. These markings include the manufacturer's brand, material identification, and fitting reference points.

They are placed outside the central viewing area so the wearer's line of sight does not pass through them. The marks help verify the lens during the cutting process.
Engravings provide different information depending on the lens type.
These marks are needed for quality control and fitting accuracy. For complex prescriptions like progressives, the engravings allow the optician to verify the lens is correctly oriented before it is cut and inserted into the frame. They are especially helpful if the prescription markings wear off during processing.
Laser engravings are virtually invisible to the wearer because they are faint and placed outside the direct line of sight. An optician can easily see them using a focimeter or a bright light source to ensure correct alignment.
No, they are placed in the periphery of the lens, outside the main viewing zone.
They are commonly found on premium, progressive, and specialized lenses.
No, they are etched into the material or coating and should not be removed.
Laser markings are the "ID card" for progressive lenses. If you aren't sure which brand of lens you are wearing, an optician can hold your glasses under a special light to read these engravings, which tell them the brand, material, and "add power."
