Powered by 3D technology for a true to scale fit, discover your perfect frame here.

Step 1

Record a selfie

Allow the tool to use your device camera and follow the instructions. Look into the camera and turn your head left and right. If you wear glasses, remove them before taking the selfie.

Step 2

Find your size

The virtual try-on tool calculates your face measurements using a standard plastic card. Take any plastic card (for example a loyalty or payment card) and use the reverse side so no data will be visible. Following the instructions, place the card on your forehead.

Step 3

Try on glasses

Now you can see how different glasses and sunglasses suit you. For best results, avoid very bright or dim light. Light conditions may impact your face readings and fitting accuracy.

Handcrafted in London, these limited-edition frames are made from 100% high-grade acetate from leading Italian manufacturer Mazzucchelli. They feature the seven-barrel hinge with genuine pin fastenings for maximum durability creating the famous 6 pin device. The Dark Tortoiseshell colourway was memorably iconised by Sir Michael Caine when he wore this frame whilst playing the character Harry Palmer in the British Spy films The Ipcress File, Funeral in Berlin and Billion Dollar Brain.

To ensure your frames fit correctly we provide key measurements in the product details.

As a guide we advise that your frames sit comfortably without any tightness or pinching. The eyebrows should generally not sit within the lens area and pupils should be in the centre. Importantly, your frames should not slip down your nose –
no matter the dramatic licence.

Glossary of terms

Bridge: The part of the frame that rests on the wearers nose.

Hinge: The interlocking metal loops holding the front and the arms together.
Rim: The part surrounding the edges of the lens.
Nose pads: The part that sits on the nose, adjusted to fit perfectly.
