About the Retro Collection Retro 355
Retro 355 Prescription Glasses
If you like structure but not sharp angles, a soft square is the sweet spot. The Retro 355 is a unisex full-rim soft square frame, sized 55-15-138, in Black, Burgundy or Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Retro Collection.
Which colour is you?
Black. Black is a deep, solid black. It is the safest choice if you only want one pair, and it never looks out of place.
Burgundy. Burgundy is a deep wine red. It is rich and confident, and it looks stunning with dark hair.
Purple. Purple is a rich purple. It works beautifully with navy, grey and silver jewellery.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Shape and style
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe.
It is the kind of frame that works with most outfits, which makes the Retro 355 an easy pick for everyday wear.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
Frame size and fit
| Brand | Retro Collection |
|---|---|
| Frame | Full Rim |
| Colours | Black, Burgundy, Purple |
| Frame size | 55-15-138 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
| Effective diameter | 54 mm |
With 55mm lenses, this is a larger frame that suits wider faces. The 15mm bridge is narrow, so it sits securely on a slimmer nose. The 138mm arms are a standard length. Across the lenses and bridge it measures about 125mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the Retro 355
Your optician’s prescription will usually tell you which of these you need:
- Single vision: the same prescription from edge to edge.
- Bifocal: distance at the top and a reading segment at the bottom.
- Varifocal: a smooth change from distance to reading, with no line.
- Ready readers: a fixed magnification for books, phones and screens.
The 39mm lens depth gives varifocal lenses plenty of room. If your prescription is high, a high-index lens keeps things thin. An anti-reflective, scratch-resistant coating is a sensible extra for everyday wear.
Before you order
Make sure your prescription is in date; most adults in the UK are advised to have an eye test every two years, and your optician will tell you if you need one sooner. You will also need your PD, which tells our lab where to centre the lenses. With those two things ready, ordering takes a few minutes: choose your colour, pick your lenses, enter your details and you are done.
Made for you in our UK lab
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Retro 355 and checked by our technicians before they are sent out.
A little care goes a long way
Clean your lenses with a microfibre cloth rather than your jumper, keep them in their case when they are in your bag, and do not leave them on a sunny car dashboard. Our lens care guide has more tips.
Questions we often get
Can I get varifocal lenses in the Retro 355?
Yes. The 39mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Retro 355 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a large frame?
Yes. With 55mm lenses it suits wider faces.
Will it suit a narrow nose?
Yes. The 15mm bridge is designed for slimmer noses.
Do you make the lenses yourselves?
Yes. Every pair is made to order in our UK optical lab, where your lenses are cut to your prescription and fitted into your frame.
