Search for replacement lenses and you'll meet two words again and again: genuine and compatible. They're priced differently, they look almost identical online, and most shops are vague about what actually separates them. Here's the honest version — so you can choose with your eyes open.
What “genuine” really means
A genuine lens is made by the manufacturer for that exact frame. For Ray-Ban that means it's cut to the original specification, carries the correct tint and coating, and is etched with the small Ray-Ban logo in the top corner of the lens. If keeping your sunglasses completely authentic matters to you — for resale value, for a collector's piece, or simply because you paid for the real thing — genuine is the only option that keeps the logo and the original optical profile intact.
What “compatible” (or aftermarket) means
A compatible lens is made by a third party to fit the same frame. The good ones are excellent — optically sharp, properly UV-rated and often available in tints Ray-Ban never offered. The trade-offs are real, though:
- No logo. For copyright reasons, aftermarket lenses can't carry the Ray-Ban etch.
- Fit varies. A lens cut a fraction out of spec can sit proud, pop loose, or stress the frame — which is how favourite pairs get cracked during a DIY swap.
- Quality is inconsistent across suppliers, especially on coatings and polarisation.
Compatible lenses earn their place when a frame is discontinued and genuine stock has run dry, or when you want a colour or finish the brand simply doesn't make.
The part most guides skip: fitting
The lens is only half the job. A lens posted to your door still has to be fitted, and a metal Aviator, a rimless frame and a chunky Wayfarer all behave differently under heat and pressure. Fit a lens badly and you risk a hairline crack in the frame or a lens that never seats cleanly. We fit every lens by hand in our workshop, check the frame alignment, and clean and polish before it comes back to you — so the repair lasts.
So which should you choose?
| Choose genuine if… | Choose compatible if… |
|---|---|
| You want the Ray-Ban logo and original look | Your model is discontinued or out of stock |
| You may resell or the pair is collectable | You want a tint Ray-Ban doesn't offer |
| The model is current and parts are available | You'd like to keep the cost down |

Reputable ones do — look for 100% UV400. We only fit lenses that meet recognised UK and EU safety standards, genuine or otherwise.
Will a non-genuine lens fit perfectly?
When it's cut to the correct model and lens size and fitted properly, yes. The risk comes from generic lenses fitted at home — which is exactly the step we take care of.
Can you put prescription lenses in Ray-Ban frames?
Yes. We can reglaze most Ray-Ban frames with single-vision, varifocal or tinted prescription lenses. Ask us about your prescription.
