About the Delancy DEL171
DEL171 Prescription Glasses
If you want a frame with a bit of attitude, start with a cat-eye. The DEL171 is a unisex full-rim cat-eye frame, sized 52-17-140, in Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Delancy collection.
The colour
Blue. In Blue, the frame is patterned blue. It brings a cool, calm touch of colour that suits most skin tones.
The details
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. The patterned finish means no two angles look quite the same.
If you want a frame you can put on in the morning and forget about, the DEL171 is a strong choice.
Wearing it every day
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Delancy |
|---|---|
| Colours | Blue |
| Frame size | 52-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 40 mm |
The 52mm lenses make this a medium frame that suits most faces. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 DEL171
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 40mm lens depth gives varifocal lenses plenty 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.
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.
How your glasses are made
Your DEL171 is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.
Keep them looking new
Clean your lenses with a microfibre cloth rather than your jumper, keep them in their case when they are in your bag, and do not leave them on a sunny car dashboard. Our lens care guide has more tips.
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 DEL171?
Yes. The 40mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the DEL171 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 52-17-140: 52mm lens width, 17mm bridge and 140mm arms, a medium fit.
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.
