About the Retro Collection Retro 393
Retro 393 Prescription Glasses
Square frames have a confident, modern look that works almost anywhere. The Retro 393 is a unisex full-rim square frame, sized 51-20-140, in Black, Brown or Navy. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Retro Collection.
3 colours to choose from
Black. The Black version is black that fades to grey. It is the safest choice if you only want one pair, and it never looks out of place.
Brown. In Brown, the frame is brown that fades to amber. It is softer than black and suits brown, auburn and red hair.
Navy. In Navy, the frame is navy that fades to grey. It reads as smart and dark from a distance, with a little more personality up close.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Why you will like it
Square lenses add structure to round and oval faces and make features look more defined. A soft colour fade defines the brow line and lets the lower half of the frame melt away.
The Retro 393 is a great everyday frame: smart enough for work and relaxed enough for the weekend. For a frame you will reach for daily, the Retro 393 is a solid choice.
Styling tips
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
Frame size and fit
| Brand | Retro Collection |
|---|---|
| Frame | Full Rim |
| Colours | Black, Brown, Navy |
| Frame size | 51-20-140 mm (lens width, bridge, arm length) |
| Lens depth | 40 mm |
| Effective diameter | 50 mm |
The 51mm lenses make this a medium frame that suits most faces. The 20mm bridge is wider than average, which suits a broader nose bridge. The 140mm arms are a standard length. Across the lenses and bridge it measures about 122mm.
The easiest way to check is against glasses you already love. Most frames show their size inside the arm; if yours are close to these, you are in safe territory.
Lens options for the Retro 393
Pick the lenses that match your prescription:
- 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 40mm lens depth gives varifocal lenses plenty of room. Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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.
From our lab to you
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Retro 393 and checked by our technicians before they are sent out.
Keep them looking new
Rinse off any grit before you wipe, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay aligned. See our lens care guide for more.
FAQs
Can I get varifocal lenses in the Retro 393?
Yes. The 40mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Retro 393 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
What size is it?
It is size 51-20-140: 51mm lens width, 20mm bridge and 140mm arms, a medium fit.
Will it suit a wider nose bridge?
Yes. The 20mm bridge is wider than most frames.
What does the colour fade look like?
The colour is darker at the top of the frame and becomes lighter towards the bottom.
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.
