About the Carlton CAR39
CAR39 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The CAR39 is a unisex full-rim metal rectangular frame, sized 54-17-140, in Black, Gold or Dark Gun. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Carlton collection.
Which colour is you?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Gold. Gold is a warm, soft gold. It is a warm, elegant choice that pairs nicely with earthy colours.
Dark Gun. The Dark Gun version is gunmetal. It is a quiet, professional finish that works with navy, charcoal and white.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Shape and style
Rectangular lenses suit round and oval faces, adding a bit of definition. The slim metal construction keeps it light and neat, and it is easy for an optician to adjust.
It is the kind of frame that works with most outfits, which makes the CAR39 an easy pick for everyday wear.
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.
Size and fit
| Brand | Carlton |
|---|---|
| Colours | Black, Gold, Dark Gun |
| Frame size | 54-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
The 54mm lenses put it at the upper end of medium. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 125mm.
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 CAR39
Pick the lenses that match your prescription:
- 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. 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.
Made for you in our UK lab
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your CAR39. Every pair is checked before it leaves us.
Looking after them
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 CAR39?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the CAR39 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
What size is it?
It is size 54-17-140: 54mm lens width, 17mm bridge and 140mm arms, a medium fit.
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.
