About the Carlton CAR36
CAR36 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The CAR36 is a unisex full-rim rectangular frame in Black, Blue or Havana. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Carlton collection.
3 colours to choose from
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Blue. The Blue version is navy. It is a fresh alternative to black that still looks professional.
Havana. The Havana version is tortoiseshell. It flatters warm and olive skin and works with almost any outfit.
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.
About the CAR36 design
Rectangular lenses suit round and oval faces, adding a bit of definition.
It is the kind of frame that works with most outfits, which makes the CAR36 an easy pick for everyday wear.
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.

Full frame measurements for the CAR36 are not listed yet. If you would like the lens width, bridge and arm length before you order, contact us and we will confirm them.
Lens options for the CAR36
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.
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.
Ordering online is simple
You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.
From our lab to you
Your CAR36 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
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.
Everyday wear
Good everyday glasses should be comfortable from breakfast to bedtime. Light materials, a secure fit and a classic look all help, and this frame ticks those boxes. Add the right lenses and it will handle screens, reading and driving with ease.
Your questions, answered
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear finish.
Can I use the CAR36 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.
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.
