About the Carlton CAR45
CAR45 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The CAR45 is a unisex full-rim rectangular frame, sized 54-16-145, in Black, Grey or Navy. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Carlton collection.
Which colour is you?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Grey. In Grey, the frame is translucent grey. It is a quiet, professional finish that works with navy, charcoal and white.
Navy. Navy is a deep, dark blue. It brings a cool, calm touch of colour that suits most skin tones.
Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition. The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
If you want a frame you can put on in the morning and forget about, the CAR45 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.
Size and fit
| Brand | Carlton |
|---|---|
| Colours | Black, Grey, Navy |
| Frame size | 54-16-145 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
The 54mm lenses put it at the upper end of medium. The 16mm bridge is on the narrow side. The 145mm arms are on the longer side, which suits larger heads. 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 CAR45
Choose the lens type that suits how you use your glasses:
- 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 38mm 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
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your CAR45. Every pair is checked before it leaves us.
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.
FAQs
Can I get varifocal lenses in the CAR45?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the CAR45 as computer glasses?
Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both work well for desk work.
What size is it?
It is size 54-16-145: 54mm lens width, 16mm bridge and 145mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
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.
