About the Top banana Three Banana
Three Banana Prescription Glasses
A round frame is an easy way to add a little character. The Three Banana is a unisex full-rim plastic round frame in Black. You can order it with single vision, progressive or bifocal lenses made to your prescription. It is part of our Top Banana collection.
The colour
Black. Black is a deep, solid black. It is the safest choice if you only want one pair, and it never looks out of place.
Why you will like it
Round frames soften angular features, so they are a great match for square and heart-shaped faces. Decorative arms give the frame a finished, designer feel when you see it side on.
A patterned front adds personality while still being easy to wear. 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 Three Banana an easy pick for everyday wear. For a frame you will reach for daily, the Three Banana is a solid choice.
How to wear it
Because it is unisex, it is easy to share the look across the household. Pick the colour that matches your wardrobe rather than worrying about who it is designed for.
How it fits
| Brand | Top banana |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Black |
| Designed for | Unisex |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide.
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 Three Banana
Your optometrist’s prescription will usually tell you which of these you need:
- Progressive lenses for clear vision at every distance without swapping pairs.
- Single vision for one job done well: driving, reading or desk work.
- Bifocal if you like a clearly marked reading section.
- Ready readers when you only need help close up.
Stronger prescription? A high-index lens keeps things thin and light. An anti-reflective, scratch-resistant coating is worth adding too, especially if you drive at night.
What you need to order
Have your prescription handy before you start. It will list the sphere, cylinder and axis for each eye, and often your PD as well. If your PD is missing, your optometrist can give it to you. Then simply choose your colour and lens type, enter your prescription and add any extras, such as a thinner lens or a coating. You can review everything in your cart before you pay.
Made for you in our UK lab
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Three Banana and then sends your glasses to you in Australia.
Keep them looking new
Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
A second pair?
Plenty of people keep more than one pair of glasses: one for work, one for home, or a spare in the car. A second pair also means you are never stuck if your main glasses are being repaired. This frame is an easy choice for either role.
Your questions, answered
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
Can I use the Three Banana as computer glasses?
Yes. Single vision lenses set to your screen distance, or progressive lenses if you also need distance vision, both work well for desk work.
Is it unisex?
Yes. It suits men and women.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
