About the Carlton CAR10
CAR10 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The CAR10 is a unisex full-rim metal rectangular frame, sized 53-17-140, in Gun Metal or Matt Black. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Carlton range.
Choosing your CAR10 colour
Gun Metal. In Gun Metal, the frame is gunmetal. It is cool, modern and understated, and it suits grey or silver hair especially well.
Matt Black. Matt Black is a soft, non-shiny black. Black suits every hair colour and frames the face with confidence.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. Metal lets the frame stay slim and light while keeping its shape.
It is the kind of frame that works with most outfits, which makes the CAR10 an easy pick for everyday wear.
Styling tips
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Carlton |
|---|---|
| Colours | Gun Metal, Matt Black |
| Frame size | 53-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 33 mm |
The 53mm lenses make this a medium frame that suits most faces. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 123mm.
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 CAR10
Your optician’s prescription will usually tell you which of these you need:
- Single vision: the same prescription from edge to edge.
- Bifocal: distance at the top and a reading segment at the bottom.
- Varifocal: a smooth change from distance to reading, with no line.
- Ready readers: a fixed magnification for books, phones and screens.
The 33mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. If your prescription is high, a high-index lens keeps things thin. An anti-reflective, scratch-resistant coating is a sensible extra for everyday wear.
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.
From our lab to you
Your CAR10 is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.
A little care goes a long way
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.
Questions we often get
Is the CAR10 suitable for varifocals?
The 33mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Is the CAR10 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 53-17-140: 53mm lens width, 17mm bridge and 140mm arms, a medium fit.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
