Twelve Banana

Twelve Banana Prescription Glasses

A clean rectangular frame works at the office, at home and everywhere in between. The Twelve Banana is a men’s full-rim plastic rectangular frame in Dark Grey, Light Grey or Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Top Banana collection.

3 colours to choose from

Dark Grey. The Dark Grey version is translucent grey. It is cool, modern and understated, and it suits grey or silver hair especially well.

Light Grey. The Light Grey version is light grey translucent. It is cool, modern and understated, and it suits grey or silver hair especially well.

Blue. The Blue version is translucent blue. It is a fresh alternative to black that still looks professional.

Each colour is shown in the gallery, so you can compare them side by side before you decide.

The details

Rectangular lenses suit round and oval faces, adding a bit of definition. The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.

Plastic keeps the weight down and allows richer, deeper colour than metal.

Whether it is your main pair or a spare, the Twelve Banana is easy to live with. The Twelve Banana also makes a handy spare pair for the car or the office.

Wearing it every day

Short hair and a clean shave make the frame shape stand out; with longer hair or a beard it reads as more relaxed.

Frame size and fit

At 55mm per lens, it is a generous size, a good pick if standard frames feel tight.

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 Twelve Banana

Choose the lens type that suits how you use your glasses:

• 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.

With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.

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

Your Twelve Banana is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.

Looking after them

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.

Your questions, answered

Is it a large frame?

Yes. With 55mm lenses it suits wider faces.

Can I wear the Twelve Banana for driving?

Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.

Where are my lenses made?

In our UK optical lab. They are cut to your prescription, fitted into your frame and checked before they are sent out.
