About the Carlton CAR44
CAR44 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The CAR44 is a unisex full-rim rectangular frame, sized 56-17-150, in Black, Grey or Crystal. 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 CAR44 colour
Black. Black is a deep, solid black. It is the safest choice if you only want one pair, and it never looks out of place.
Grey. In Grey, the frame is translucent grey. It goes with almost everything and never draws too much attention.
Crystal. The Crystal version is crystal clear. It keeps the look soft and understated, and it works especially well on fair skin.
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 CAR44 design
Rectangular lenses suit round and oval faces, adding a bit of definition. The crystal finish is clear and fresh, and it lets your features take centre stage.
The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
It is the kind of frame that works with most outfits, which makes the CAR44 an easy pick for everyday wear.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Carlton |
|---|---|
| Colours | Black, Grey, Crystal |
| Frame size | 56-17-150 mm (lens width, bridge, arm length) |
| Lens depth | 40 mm |
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 CAR44
Your optician’s prescription will usually tell you which of these you need:
- 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. 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.
Before you order
Make sure your prescription is in date; most adults in the UK are advised to have an eye test every two years, and your optician will tell you if you need one sooner. You will also need your PD, which tells our lab where to centre the lenses. With those two things ready, ordering takes a few minutes: choose your colour, pick your lenses, enter your details and you are done.
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 CAR44 and checked by our technicians before they are sent out.
Looking after them
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.
Questions we often get
Can I get varifocal lenses in the CAR44?
Yes. The 40mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the CAR44 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a large frame?
Yes. With 56mm lenses it suits wider faces.
What does crystal mean?
A clear, see-through finish.
Do you make the lenses yourselves?
Yes. Every pair is made to order in our UK optical lab, where your lenses are cut to your prescription and fitted into your frame.
