The 2026 Black Friday Reality Check: Telling Real Designer Sunglasses From a Very Good Copy

Black Friday lands on 27 November in 2026, but the deals started creeping into mid-November a long time ago. For sunglasses, that means the next fortnight is a blizzard of 60%-off banners, countdown timers and marketplace listings that look almost right. Almost is the problem.

Counterfeit sunglasses have moved well beyond the bloke at the car boot sale. Modern fakes come with convincing boxes, ghost-written serial numbers and photography that's either stolen or generated. So the checks below are less about spotting an obvious fake and more about interrogating the listing before your money leaves your account.

Start with the seller, not the sunglasses

This is the single most useful habit. Ignore the product page entirely for two minutes and look at who's actually selling.

• Is there a real UK address and a company number? Check the number against Companies House. It takes ninety seconds.
• How old is the website? A domain registered eight weeks ago with a slick designer layout is a classic pop-up.
• Is the contact route a form and nothing else? No phone, no postal address, no named person — treat that as a warning.
• On marketplaces, find the line that says who it's sold and dispatched by. A familiar marketplace logo means nothing if the actual seller is an unknown third party.
• Read the two-star reviews first. Not the one-stars, which are often about delivery, and not the fives, which are often about nothing. The twos and threes tell you what a shop is like when something goes slightly wrong.

The price is doing more talking than you think

Genuine current-season Ray-Ban, Persol, Oakley, Tom Ford or Gucci stock has a floor. Authorised retailers discount, but they don't routinely knock 75% off a pair that's still on the brand's own website. A price that's dramatically out of line with John Lewis, Boots Opticians, Sunglass Hut and the brand's own store is not a bargain — it's information.

Older, discontinued colourways and end-of-line shapes genuinely do get cleared out at steep reductions. That's legitimate. The tell is whether the listing is a specific, slightly odd colour code or a generic 'black, one size' with no detail at all.

Model numbers, colour codes and the numbers game

Every proper pair has a model code and a colour code printed on the inside of the left temple — something like RB2140 901 or PO0714 24/31. Those two codes should match the product page, the box label and the brand's own site. Search the exact code plus the word 'review' and you'll often find the official colourway.

Look for the small print while you're there: frame size numbers (lens, bridge, temple in millimetres), the country of manufacture, the CE or UKCA marking and — from recent years — a UK importer address. Fakes frequently get the temple print right and the box label wrong, or vice versa. Mismatches between the two are a hard no.

The lens etching: small, specific and hard to fake well

This is where the copies tend to stumble.

• Ray-Ban etches the logo into the right lens, and it should be crisp, faint and only visible at an angle. On fakes it's often too deep, too dark or lasered slightly off-centre.
• Persol uses an arrow motif on the lens along with its signature silver arrow hinge. The hinge mechanism is genuinely difficult to replicate cheaply — check it moves cleanly rather than rattling.
• Oakley etches the model or Prizm logo into the lens, and the frame finish usually has a very specific texture.
• Chrome Hearts, Cartier and other premium metal frames lean on engraving, weight and hinge quality. If a listing won't show you a close-up of the hinge, ask yourself why.

Ask the seller for a photograph of the actual pair — not the stock image. A refusal, or an offer to send one 'after purchase', ends the conversation.

Packaging in 2026: AI images and QR codes

Product photography is now the easiest thing in the world to fake. Generated images give themselves away with logos that warp slightly, text that goes fuzzy at the edges, lens reflections that don't match the environment, and cases that look suspiciously smooth. Zoom in. Check the temple print in the image is legible and consistent.

Legitimate packaging details to look for: a hard case with clean stitching and correctly aligned branding, a cleaning cloth that matches the brand, a warranty or authenticity card with a matching serial, and — increasingly — a QR code on the box or card that resolves to the brand's own verification page. Scan it. If it goes nowhere, or to a page that isn't the brand's domain, that's your answer.

The warranty is where the grey market shows itself

Grey-market stock is genuine product sold outside the brand's authorised channel. It's not automatically fake, but it usually comes without the manufacturer's UK warranty, and any issue becomes a fight with a seller rather than a conversation with a brand.

Ask, in writing: does this come with the full manufacturer warranty valid in the UK, and will you provide a VAT receipt? An authorised retailer will answer without blinking. A grey importer will get vague.

Your safety net is the returns policy

Under UK distance selling rules you generally have 14 days from delivery to cancel an online order and send it back, for any reason. That right exists regardless of what a site's FAQ claims.

Before buying, read the returns page properly. Red flags: no returns accepted, restocking fees, a return address outside the UK, a window shorter than 14 days, or a policy that only covers faulty items. Screenshot the policy at the time of purchase — pages change once a sale ends.

If the pair arrives and something's off

Don't wear them outside. Photograph everything: the frames, the temple print, the lens etching, the box, the cards, the packaging as it arrived. Then email the seller rather than messaging through a marketplace chat, so you have a clean record.

If they won't play ball, you have routes. Card payments over £100 may be covered by Section 75 of the Consumer Credit Act; PayPal and most card providers also run chargeback schemes. Report suspected counterfeits to Trading Standards via Citizens Advice, and to Action Fraud if money has been lost. It sounds bureaucratic, but these reports are what eventually close the sites down.

One last thing: if the deal feels engineered to stop you thinking — twelve hours left, nine people viewing, one pair remaining in your size — that's not urgency, that's pressure. Real sunglasses will still be there tomorrow. Copies are designed to catch you today.
