About the Carlton CAR28
CAR28 Prescription Glasses
A round frame is an easy way to add a little character. The CAR28 is a unisex full-rim round frame, sized 50-18-140, in Black, Crystal or Havana. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Carlton range.
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. In Crystal, the frame is crystal clear. It keeps the look soft and understated, and it works especially well on fair skin.
Havana. The Havana version is tortoiseshell. It is softer than black and suits brown, auburn and red hair.
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 CAR28 design
Round frames soften angular features, so they are a great match for square and heart-shaped faces. The crystal finish is clear and fresh, and it lets your features take centre stage.
Whether it is your main pair or a spare, the CAR28 is easy to live with.
Styling tips
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.
Frame size and fit
| Brand | Carlton |
|---|---|
| Colours | Black, Crystal, Havana |
| Frame size | 50-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 43 mm |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.
Lens options for the CAR28
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.
At 43mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. If your prescription is high, a high-index lens keeps things thin. An anti-reflective, scratch-resistant coating is a sensible extra for everyday wear.
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
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your CAR28. Every pair is checked before it leaves us.
Keep them looking new
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 CAR28?
Yes. The 43mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the CAR28 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 small frame?
Yes. With 50mm lenses it suits smaller faces.
What does crystal mean?
A clear, see-through finish.
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.
