How to spot authentic vintage Ray-Ban sunglasses

Why vintage Ray-Ban is the most faked eyewear on the market

Frames made in Rochester by Bausch & Lomb between the 1930s and 1999 are among the most collected optical objects in the world. A genuine Aviator or Wayfarer from that era uses tempered glass lenses, treated metal or pressed acetate, and build tolerances that modern reproductions rarely match. That is exactly why the resale market is full of re-marked pieces, frames assembled from non-original parts, and recent production sold as vintage.

1. Read the lens markings

On an authentic Bausch & Lomb piece the "B&L" mark sits at the top left of the left lens: small, crisp, aligned with the rim, and impossible to scratch off with a fingernail. Reproductions typically show a mark that is too large, blurry, off-centre, or applied as a sticker. From 2000 onwards the correct mark is "RB" with the Luxottica logo, so a frame advertised as 1980s stock that carries "RB" is not what it claims to be.

2. Inspect the inside of the temples

The inner right temple carries the model name, the eye size and the country of manufacture, for example "B&L Ray-Ban U.S.A." followed by the measurements. The left temple usually carries the model code and the colour code. Original engravings are deep, evenly spaced and typographically consistent; shallow, smudged or mismatched fonts are the single most common red flag.

3. Hinges, screws and finishing

Authentic hinges are multi-barrel, precisely welded and free of lateral play. Opening and closing a temple feels smooth and silent. Star-head screws, plastic hinges, excess solder or plating that reveals raw metal underneath almost always indicate non-original production or a non-conforming repair.

4. Weight and the sound of glass

Glass lenses are noticeably heavier than polycarbonate and, tapped gently with a fingernail, they return a dry, crystalline sound. A 1970s Aviator that feels feather light and sounds plastic has almost certainly been re-lensed. That does not make the frame fake, but it does change the value and must be disclosed in the listing.

5. Case, paperwork and historical coherence

An original case, cloth and booklet help, but they prove little on their own because they are the easiest parts to source separately. What matters is overall coherence: a model launched in 1986 cannot ship in a case bearing a logo introduced in the 2000s. Always check that the production period, the markings and the accessories tell the same story.

How FRAMEO authentication works

Every FRAMEO listing requires a standard photo set: front, inner temples, hinges, lenses and defects. Our team runs a digital authentication checklist against those images, and higher-value pieces can also be inspected physically before they reach the buyer. The outcome is published on the listing page alongside the condition of each component.

Quick buyer checklist

If a seller cannot photograph the inside of the temples, pause the purchase. If the price is far below the market average for that reference, ask for measurements and macro shots of the markings. If a frame discontinued decades ago looks "as new", ask about provenance: deadstock exists, but it should be documented.
