About the Paul Costelloe Collection Paul Costelloe 5259
Paul Costelloe 5259 Prescription Glasses
Some frames just suit almost everyone. Rounded squares are high on that list. The Paul Costelloe 5259 is a unisex full-rim rounded square frame, sized 50-19-140, in Black, Brown Mottle or Burgundy Mottle. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Paul Costelloe Collection.
Which colour is you?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Brown Mottle. Brown Mottle is a mottled brown. It is softer than black and suits brown, auburn and red hair.
Burgundy Mottle. Burgundy Mottle keeps things simple. It flatters warm and olive skin and works with almost any outfit.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
The details
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces.
It is the kind of frame that works with most outfits, which makes the Paul Costelloe 5259 an easy pick for everyday wear.
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 | Paul Costelloe Collection |
|---|---|
| Frame | Full Rim |
| Colours | Black, Brown Mottle, Burgundy Mottle |
| Frame size | 50-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
| Effective diameter | 50 mm |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
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 5259
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.
At 41mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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.
Made for you in our UK lab
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Paul Costelloe 5259 and checked by our technicians before they are sent out.
Looking after them
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.
FAQs
Can I get varifocal lenses in the Paul Costelloe 5259?
Yes. The 41mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Paul Costelloe 5259 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
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.
