About the Top banana Four Banana
Four Banana Prescription Glasses
If you like structure but not sharp angles, a soft square is the sweet spot. The Four Banana is a women’s full-rim plastic soft square frame in Matt Black, Dark Purple or Navy/Red. You can order it with single vision, progressive or bifocal lenses made to your prescription. It is part of our Top Banana range.
Choosing your Four Banana colour
Matt Black. Matt Black is a soft, non-shiny black. It is the safest choice if you only want one pair, and it never looks out of place.
Dark Purple. Dark Purple keeps things simple. It brings a little personality without overpowering your features.
Navy/Red. Navy/Red pairs navy with red. 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.
Design details
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. Plastic keeps the weight down and allows richer, deeper colour than metal.
If you want a frame you can put on in the morning and forget about, the Four Banana is a strong choice.
Wearing it every day
Match the frame colour to something you wear often, such as a favourite scarf or bag, for a pulled-together look. Neutral make-up keeps the focus on your eyes.
How it fits
| Brand | Top banana |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Matt Black, Dark Purple, Navy/Red |
| Designed for | Women |
The 52mm lenses make this a medium frame that suits most faces.
Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.
Lens options for the Four Banana
Your optometrist’s prescription will usually tell you which of these you need:
- Single vision: one prescription for distance, reading or the computer.
- Progressive: near, middle and far in one lens with no line. (In the UK they call them varifocals.)
- Bifocal: a defined reading area at the bottom of the lens.
- Ready readers: simple magnification for close work.
Prefer to keep things slim? Choose a high-index lens, which is thinner and lighter than standard. Then add an anti-reflective coating to cut glare from headlights and screens.
Ordering online is easier than you think
All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.
From our lab to you
Once you have picked your colour and lens type and entered your prescription and PD, our UK optical lab makes your lenses, fits them into your Four Banana and sends the finished pair to you in Australia.
Keep them looking new
Wipe your lenses with a microfibre cloth rather than the hem of your shirt, keep them in a case when they are in your bag, and never leave them on the dashboard on a hot day. Our lens care guide has a few more habits worth picking up.
Your questions, answered
Is the Four Banana 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.
Where are my lenses made?
In our UK optical lab. They are cut to your prescription, fitted into your frame and then sent to you in Australia.
