About the Delancy DEL187
DEL187 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The DEL187 is a unisex full-rim rectangular frame, sized 51-18-140, in Black or Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Delancy collection.
Choosing your DEL187 colour
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Blue. Blue is a clear, easy-to-wear blue. It is a fresh alternative to black that still looks professional.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. The arms carry a decorative pattern that adds a bit of jewellery to the frame.
The patterned finish means no two angles look quite the same.
The DEL187 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Wearing it every day
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.
Frame size and fit
| Brand | Delancy |
|---|---|
| Colours | Black, Blue |
| Frame size | 51-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 120mm.
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 DEL187
Pick the lenses that match your prescription:
- 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 38mm 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.
From our lab to you
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your DEL187 and checked by our technicians before they are sent out.
A little care goes a long way
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.
Questions we often get
Can I get varifocal lenses in the DEL187?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the DEL187 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 51-18-140: 51mm lens width, 18mm 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.
