About the Carlton CAR26
CAR26 Prescription Glasses
A round frame is an easy way to add a little character. The CAR26 is a unisex full-rim round frame, sized 51-19-140, in Black, Crystal or Havana. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Carlton collection.
3 colours to choose from
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.
Crystal. The Crystal version is crystal clear. Because light passes through it, the frame looks lighter on the face and lets your features do the talking.
Havana. The Havana version is tortoiseshell. It is softer than black and suits brown, auburn and red hair.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Shape and style
Round frames soften angular features, so they are a great match for square and heart-shaped faces. A crystal front looks modern and light, and it goes with everything.
It is the kind of frame that works with most outfits, which makes the CAR26 an easy pick for everyday wear.
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.
How it fits
| Brand | Carlton |
|---|---|
| Colours | Black, Crystal, Havana |
| Frame size | 51-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 44 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 CAR26
Choose the lens type that suits how you use your glasses:
- 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.
At 44mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. 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.
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.
Made for you in our UK lab
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your CAR26 and checked by our technicians before they are sent 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.
FAQs
Can I get varifocal lenses in the CAR26?
Yes. The 44mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the CAR26 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 51-19-140: 51mm lens width, 19mm bridge and 140mm arms, a medium fit.
What does crystal mean?
A clear, see-through finish.
Who glazes my lenses?
