About the Carlton CAR13
CAR13 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The CAR13 is a unisex full-rim metal rectangular frame, sized 53-18-140, in Dark Gun. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Carlton range.
The colour
Dark Gun. The Dark Gun version is gunmetal. It is cool, modern and understated, and it suits grey or silver hair especially well.
About the CAR13 design
Rectangular lenses suit round and oval faces, adding a bit of definition. Metal lets the frame stay slim and light while keeping its shape.
If you want a frame you can put on in the morning and forget about, the CAR13 is a strong choice.
Wearing it every day
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Carlton |
|---|---|
| Colours | Dark Gun |
| Frame size | 53-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
At 53mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 124mm.
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 CAR13
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.
The 36mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
What you will need
Have your prescription to hand before you start. It shows the sphere, cylinder and axis for each eye, and sometimes your PD. If the PD is missing, your optician can give it to you. Then choose your colour and lens type, enter your prescription and add any extras, such as thinner lenses or a coating. You can check everything in your basket before you pay.
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 CAR13 and checked by our technicians before they are sent out.
Looking after them
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.
Who it is for
This frame is a good fit for anyone who wants reliable everyday glasses without fuss. It works for long days at a desk, the school run, driving and catching up with friends, and it pairs with most wardrobes. If you are replacing an old pair, compare the measurements above with the glasses you wear now.
FAQs
Can I get varifocal lenses in the CAR13?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the CAR13 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.
What size is it?
It is size 53-18-140: 53mm lens width, 18mm bridge and 140mm arms, a medium fit.
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.
