Paul Costelloe 5241

Paul Costelloe 5241 Prescription Glasses

Square frames add definition without trying too hard. The Paul Costelloe 5241 is a unisex full-rim stainless steel square frame, sized 51-18-145, in Black/Gold or Black/Silver. 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 5241 colour

Black/Gold. In Black/Gold, the frame is black and gold. It is the safest choice if you only want one pair, and it never looks out of place.

Black/Silver. The Black/Silver version is black and silver. It defines the eyes and goes with every outfit you own.

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

Square lenses add structure to round and oval faces and make features look more defined. Stainless steel is strong, light and resistant to corrosion, so the frame keeps its finish over time.

The Paul Costelloe 5241 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.

Frame size and fit

At 51mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 120mm.

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 Paul Costelloe 5241

Your optician’s prescription will usually tell you which of these you need:

• 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 42mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. 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.
