Identify Varilux Lenses Using Laser Engravings and Authenticity Cards

To identify Varilux lenses, look for semi-visible laser engravings on the surface by holding them toward a light source. These markings appear near the outer edges of the lens. Additionally, genuine lenses are issued with a physical or digital certificate of authenticity that contains a unique tracking number and product specifications for verification.

Visual Inspection of Laser Markings

• Light Exposure: Hold the lens at an angle under a bright, concentrated light source to reveal hidden etchings.
• Check Edges: Look near the nasal side (near the bridge) and the temporal side (near the temple) for microscopic symbols.
• Identify Logos: Look for a stylized symbol or specific letter combinations that represent the lens design.
• Magnification: Use a magnifying glass to clearly see small alphanumeric codes that indicate the lens material and index.

Methods for Verifying Lens Authenticity

Decoding the Engraved Symbols

The markings on the lenses serve as permanent identification records. These symbols remain on the lens even after it is shaped and cut to fit a specific frame. These codes usually represent specific technical information:

• Nasal Markings: These symbols usually identify the specific series or the generation of the progressive lens design.
• Temporal Markings: These markings often indicate the refractive index of the lens material and the prescribed addition power.

Using Official Documentation

The most reliable way to confirm your lenses is through the official identification card provided at the time of purchase. This card provides a direct link to the manufacturing data. If the card is unavailable, an eye care professional can use a specialized lamp to highlight the engravings for easier confirmation of the product model.
