About the Dune DUN036
DUN036 Prescription Glasses
A cat-eye is one of the most flattering shapes you can wear. The DUN036 is a unisex full-rim cat-eye frame, sized 50-15-140, in Blue or Matt Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Dune collection.
Blue or Matt Purple: which one is you?
Blue. The Blue version is patterned blue. It reads as smart and dark from a distance, with a little more personality up close.
Matt Purple. The Matt Purple version is patterned purple. It adds a confident touch of colour and suits fair and cool skin tones.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. A patterned front adds personality while still being easy to wear.
If you want a frame you can put on in the morning and forget about, the DUN036 is a strong choice.
Styling tips
Choose the colour closest to what you wear most and it will go with almost everything.
Frame size and fit
| Brand | Dune |
|---|---|
| Colours | Blue, Matt Purple |
| Frame size | 50-15-140 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 15mm bridge is narrow, so it sits securely on a slimmer nose. The 140mm arms are a standard length. Across the lenses and bridge it measures about 115mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the DUN036
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.
The 37mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
How your glasses are made
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your DUN036. Every pair is checked before it leaves us.
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
Can I get varifocal lenses in the DUN036?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the DUN036 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
Will it suit a narrow nose?
Yes. The 15mm bridge is designed for slimmer noses.
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.
