About the Paul Costelloe Collection Paul Costelloe 5251
Paul Costelloe 5251 Prescription Glasses
Flat edges and angles turn a simple frame into a talking point. 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, progressive or bifocal lenses made to your prescription. It is part of our Paul Costelloe Collection.
3 colours to choose from
Gold / Silver. Gold / Silver pairs gold with silver. It brings warmth to the face and looks lovely with gold jewellery or a watch.
Rose. The Rose version is rose gold. It pairs nicely with neutrals, white and rose gold jewellery.
Silver / Teal. Silver / Teal pairs silver with teal. It is a great match for cooler skin tones and a crisp, tidy look.
Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.
The 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.
The Paul Costelloe 5251 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| 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 |
At 51mm per lens, it sits in the medium range, the most common adult fit. 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.
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 Paul Costelloe 5251
Choose the lens type that suits how you use your glasses:
- Single vision: one clear prescription across the whole lens.
- Bifocal: distance on top, a reading segment below.
- Progressive: smooth vision from near to far in one lens, no line.
- Ready readers: off-the-shelf magnification for books and screens.
At 46mm, the lens depth is deeper than most frames in our range, so progressive lenses have lots of room. Prefer to keep things slim? Choose a high-index lens, which is thinner and lighter than standard. Then add an anti-reflective coating to cut glare from headlights and screens.
Ordering online is easier than you think
All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.
How your glasses are made
Once you have picked your colour and lens type and entered your prescription and PD, our UK optical lab makes your lenses, fits them into your Paul Costelloe 5251 and sends the finished pair to you in Australia.
A little care goes a long way
Clean the lenses with lens spray and a soft cloth, fold the arms before you put them down, and keep them in a hard case when they are not on your face. Our guide to caring for your lenses covers the rest.
FAQs
Can I get progressive lenses in the Paul Costelloe 5251?
Yes. The 46mm lens depth gives progressive lenses enough height for all three vision zones.
Can I wear the Paul Costelloe 5251 for driving?
Yes. Single vision or progressive lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-19-135: 51mm lens width, 19mm bridge and 135mm 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.
