About the Top banana Eighteen Banana
Eighteen Banana Prescription Glasses
Geometric frames are for people who like their glasses to be a little bit interesting. The Eighteen Banana is a unisex full-rim plastic geometric frame in Blue, Black or Pink Sparkle. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Top Banana range.
Choosing your Eighteen Banana colour
Blue. Blue is a clear, easy-to-wear blue. It reads as smart and dark from a distance, with a little more personality up close.
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Pink Sparkle. Pink Sparkle keeps things simple. It is soft and pretty, and it suits fair and cool skin tones.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Design details
The angular shape suits round and oval faces, where it adds definition and interest. Take a look at the arms: the detailing there is what makes this frame special.
Tortoiseshell arms add warmth and a classic finishing touch. The patterned finish means no two angles look quite the same. Plastic keeps the weight down and allows richer, deeper colour than metal.
It is the kind of frame that works with most outfits, which makes the Eighteen Banana an easy pick for everyday wear.
Styling tips
It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.

Lens options for the Eighteen Banana
Choose the lens type that suits how you use your glasses:
- 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.
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.
What you will need
Have your prescription to hand before you start. It shows the sphere, cylinder and axis for each eye, and sometimes your PD. If the PD is missing, your optician can give it to you. Then choose your colour and lens type, enter your prescription and add any extras, such as thinner lenses or a coating. You can check everything in your basket before you pay.
How your glasses are made
Your Eighteen 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
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
Your questions, answered
Is it unisex?
Yes. It suits men and women.
Can I use the Eighteen Banana as computer glasses?
Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both work well for desk work.
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.
