About the Delancy DEL178
DEL178 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The DEL178 is a unisex full-rim rectangular frame, sized 54-17-140, in Grey. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Delancy range.
The colour
Grey. Grey is a soft, neutral grey. It goes with almost everything and never draws too much attention.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition.
The DEL178 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
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.
Frame size and fit
| Brand | Delancy |
|---|---|
| Colours | Grey |
| Frame size | 54-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
The 54mm lenses put it at the upper end of medium. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 125mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the DEL178
Choose the lens type that suits how you use your glasses:
- 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 39mm 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
Your DEL178 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.
Looking after them
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 DEL178?
Yes. The 39mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the DEL178 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 54-17-140: 54mm lens width, 17mm bridge and 140mm arms, a medium fit.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
