About the Paul Costelloe Collection Paul Costelloe 5251
Paul Costelloe 5251 Prescription Glasses
Geometric frames are for people who like their glasses to be a little bit interesting. The Paul Costelloe 5251 is a unisex full-rim metal geometric frame, sized 51-19-135, in Gold / Silver, Rose or Silver / Teal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Paul Costelloe Collection.
Choosing your Paul Costelloe 5251 colour
Gold / Silver. Gold / Silver pairs gold with silver. It suits warm and olive skin tones beautifully.
Rose. In Rose, the frame is rose gold. It is soft and pretty, and it suits fair and cool skin tones.
Silver / Teal. Silver / Teal pairs silver with teal. It goes with almost everything and never draws too much attention.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Design details
The angular shape suits round and oval faces, where it adds definition and interest. Metal lets the frame stay slim and light while keeping its shape.
It is the kind of frame that works with most outfits, which makes the Paul Costelloe 5251 an easy pick for everyday wear.
Styling tips
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 | Paul Costelloe Collection |
|---|---|
| Frame | Full Rim |
| Colours | Gold / Silver, Rose, Silver / Teal |
| Frame size | 51-19-135 mm (lens width, bridge, arm length) |
| Lens depth | 46 mm |
| Effective diameter | 51 mm |
The 51mm lenses make this a medium frame that suits most faces. The 19mm bridge is a little wider than average. The 135mm 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 Paul Costelloe 5251
Pick the lenses that match your prescription:
- Single vision: one prescription across the whole lens, for distance, reading or the computer.
- Varifocal: near, intermediate and distance in one lens, with no visible line.
- Bifocal: a separate reading segment in the lower part of the lens.
- Ready readers: simple magnification if you just need help with close work.
At 46mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots 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.
Before you order
Make sure your prescription is in date; most adults in the UK are advised to have an eye test every two years, and your optician will tell you if you need one sooner. You will also need your PD, which tells our lab where to centre the lenses. With those two things ready, ordering takes a few minutes: choose your colour, pick your lenses, enter your details and you are done.
How your glasses are made
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Paul Costelloe 5251 and checked by our technicians before they are sent out.
A little care goes a long way
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.
