CAR31

CAR31 Prescription Glasses

Rectangular frames are the dependable all-rounders of eyewear. The CAR31 is a unisex full-rim rectangular frame, sized 56-17-150, in Black or Dark Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Carlton collection.

Choosing your CAR31 colour

Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.

Dark Blue. The Dark Blue version is navy. It is a fresh alternative to black that still looks professional.

If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.

About the CAR31 design

Rectangular lenses suit round and oval faces, adding a bit of definition.

The CAR31 is a great everyday frame: smart enough for work and relaxed enough for the weekend.

Styling tips

Choose the colour closest to what you wear most and it will go with almost everything.

How it fits

With 56mm lenses, this is a larger frame that suits wider faces. The 17mm bridge is average. The 150mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 129mm.

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 CAR31

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 40mm lens depth gives varifocal lenses plenty 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.

From our lab to you

Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your CAR31 and checked by our technicians before they are sent out.

Keep them looking new

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.

Everyday wear

Good everyday glasses should be comfortable from breakfast to bedtime. Light materials, a secure fit and a classic look all help, and this frame ticks those boxes. Add the right lenses and it will handle screens, reading and driving with ease.

FAQs

Can I get varifocal lenses in the CAR31?

Yes. The 40mm lens depth gives varifocal lenses enough height for all three vision zones.

Is the CAR31 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 large frame?

Yes. With 56mm lenses it suits wider 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.
