About the Delancy DEL173
DEL173 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The DEL173 is a unisex full-rim rectangular frame, sized 55-16-145, in Matt Black, Matt Blue or Matt Grey. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Delancy range.
Which colour is you?
Matt Black. Matt Black is a soft, non-shiny black. It defines the eyes and goes with every outfit you own.
Matt Blue. In Matt Blue, the frame is navy. It is a fresh alternative to black that still looks professional.
Matt Grey. Matt Grey is a soft, non-shiny grey. It is cool, modern and understated, and it suits grey or silver hair especially well.
Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.
About the DEL173 design
Rectangular lenses suit round and oval faces, adding a bit of definition.
If you want a frame you can put on in the morning and forget about, the DEL173 is a strong choice.
Wearing it every day
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Delancy |
|---|---|
| Colours | Matt Black, Matt Blue, Matt Grey |
| Frame size | 55-16-145 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
With 55mm lenses, this is a larger frame that suits wider faces. The 16mm bridge is on the narrow side. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 126mm.
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 DEL173
Choose the lens type that suits how you use your glasses:
- 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.
The 36mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
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.
From our lab to you
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your DEL173. 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 DEL173?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the DEL173 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.
Is it a large frame?
Yes. With 55mm lenses it suits wider faces.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
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.
