Thirteen Banana

Thirteen Banana Prescription Glasses

Some frames just suit almost everyone. Rounded squares are high on that list. The Thirteen Banana is a unisex full-rim plastic rounded square 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 range.

Choosing your Thirteen Banana colour

Dark Grey. In Dark Grey, the frame 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 a great match for cooler skin tones and a crisp, tidy look.

Blue. The Blue version is translucent blue. It looks great with blue or grey eyes and pairs easily with denim and white.

Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.

The details

The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces. Because the colour is see-through, the frame has a light, glowing look.

The plastic frame is light on the nose and comfortable for all-day wear.

Whether it is your main pair or a spare, the Thirteen Banana is easy to live with.

Styling tips

It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.

Size and fit

With 50mm lenses, this is a compact frame that suits smaller faces.

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 Thirteen Banana

Your optician’s prescription will usually tell you which of these you need:

• Varifocals if you want to see near and far without swapping glasses.
• Single vision for one task done well, such as driving, reading or screen work.
• Bifocals if you prefer a clearly defined reading area.
• Ready readers for straightforward close-up help.

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

Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Thirteen Banana. Every pair is checked before it leaves us.

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.

Yes. With 50mm lenses it suits smaller faces.

Can I use the Thirteen Banana as computer glasses?
