About the Carlton CAR17
CAR17 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The CAR17 is a unisex full-rim metal rectangular frame, sized 54-18-145, in Gun Metal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Carlton collection.
Colour and finish
Gun Metal. In Gun Metal, the frame is gunmetal. It is a quiet, professional finish that works with navy, charcoal and white.
Shape and style
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 CAR17 is a strong choice.
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 | Carlton |
|---|---|
| Colours | Gun Metal |
| Frame size | 54-18-145 mm (lens width, bridge, arm length) |
| Lens depth | 32 mm |
The 54mm lenses put it at the upper end of medium. 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 126mm.
Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.
Lens options for the CAR17
Choose the lens type that suits how you use your glasses:
- 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 32mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
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 CAR17 and checked by our technicians before they are sent out.
Keep them looking new
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
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.
Questions we often get
Is the CAR17 suitable for varifocals?
The 32mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I wear the CAR17 for driving?
Yes. Single vision lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 54-18-145: 54mm lens width, 18mm bridge and 145mm 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.
