About the Delancy DEL188
DEL188 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The DEL188 is a unisex full-rim rectangular frame, sized 54-16-140, in Black, Blue or Green. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Delancy range.
3 colours to choose from
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.
Green. The Green version is green tortoiseshell. It feels fresh and a little bit different, which is exactly why people notice it.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
About the DEL188 design
Rectangular lenses suit round and oval faces, adding a bit of definition.
The DEL188 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.
How it fits
| Brand | Delancy |
|---|---|
| Colours | Black, Blue, Green |
| Frame size | 54-16-140 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
The 54mm lenses put it at the upper end of medium. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 124mm.
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 DEL188
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.
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.
Ordering online is simple
You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.
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 DEL188. 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.
Your questions, answered
Can I get varifocal lenses in the DEL188?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the DEL188 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.
What size is it?
It is size 54-16-140: 54mm lens width, 16mm bridge and 140mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 16mm 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.
