Identifying your sunglasses frame

Each set of replacement lenses is engineered for one specific frame variant, and even a slight difference in shape or size will be noticeable. Knowing your model number alongside the lens width lets us pinpoint exactly which version of the frame you own, so the finished lens sits properly and functions as intended.

If there's genuinely nothing to see, your quickest option is to email clear photographs — the front of the frame, both inside temple arms, and any faded markings — and our optical team will take it from there. Already know your brand and model but just need the size? Take one lens out and measure its widest point in a straight line with a ruler, ignoring the curve. That reading in millimetres gives you the lens width.

Not at all — every manufacturer has its own conventions, and even the placement of sizing information changes from brand to brand. Some frames also add a letter such as 'S' or 'XL' next to the model name, which can point to a completely different lens shape rather than simply a size variation. If you're at all unsure, a direct measurement of your lens is the most reliable way to confirm.

It helps to take the lens out of the frame beforehand, as measuring through the opening can distort the result. Lay it flat and measure the widest point edge to edge in a straight line, without following the curve of the lens. That measurement, taken in millimetres, is your lens width.

Yes, certainly. Send us clear photographs of the frame's front, the inside of both temple arms, and any markings you can make out, even if partly worn. Having identified thousands of frames, our optical team can typically steer you in the right direction. And if your model turns out to be discontinued or truly one-off, our bespoke lens service can still craft a precision-fit pair.
