About the Dune DUN037
DUN037 Prescription Glasses
There is something friendly and approachable about a round frame. The DUN037 is a unisex full-rim round frame, sized 48-19-140, in Matt Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Dune collection.
The colour
Matt Purple. In Matt Purple, the frame is translucent lilac. It is softer than it sounds and looks lovely with grey or silver hair.
Why you will like it
Round frames soften angular features, so they are a great match for square and heart-shaped faces. Because the colour is see-through, the frame has a light, glowing look.
It is the kind of frame that works with most outfits, which makes the DUN037 an easy pick for everyday wear.
How to wear it
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
Size and fit
| Brand | Dune |
|---|---|
| Colours | Matt Purple |
| Frame size | 48-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
With 48mm lenses, this is a compact frame that suits smaller faces. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 115mm.
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 DUN037
Pick the lenses that match your prescription:
- Single vision: the same prescription from edge to edge.
- Bifocal: distance at the top and a reading segment at the bottom.
- Varifocal: a smooth change from distance to reading, with no line.
- Ready readers: a fixed magnification for books, phones and screens.
At 41mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. If your prescription is high, a high-index lens keeps things thin. An anti-reflective, scratch-resistant coating is a sensible extra for everyday wear.
Before you order
Make sure your prescription is in date; most adults in Canada are advised to have an eye exam every two years, and your optometrist 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 DUN037. 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.
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.
FAQs
Can I get varifocal lenses in the DUN037?
Yes. The 41mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the DUN037 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.
Is it a small frame?
Yes. With 48mm lenses it suits smaller faces.
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.
