About the Carlton CAR03
CAR03 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The CAR03 is a unisex full-rim rectangular frame, sized 52-16-140, in Black or Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Carlton collection.
Choosing your CAR03 colour
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Blue. In Blue, the frame is navy. It reads as smart and dark from a distance, with a little more personality up close.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition.
Whether it is your main pair or a spare, the CAR03 is easy to live with.
Wearing it every day
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, Blue |
| Frame size | 52-16-140 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 120mm.
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 CAR03
Pick the lenses that match your prescription:
- 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 36mm lens depth works with single vision, bifocal and many varifocal lenses. Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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 CAR03 and checked by our technicians before they are sent out.
A little care goes a long way
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.
Questions we often get
Can I get varifocal lenses in the CAR03?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the CAR03 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 52-16-140: 52mm lens width, 16mm bridge and 140mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
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.
