About the Carlton CAR04
CAR04 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The CAR04 is a unisex full-rim rectangular frame, sized 52-17-140, in Black or Blue. You can order it with single vision, progressive or bifocal lenses made to your prescription. It belongs to the Carlton collection.
Black or Blue?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Blue. The Blue version is navy. It brings a cool, calm touch of colour that suits most skin tones.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
About the CAR04 design
Rectangular lenses suit round and oval faces, adding a bit of definition.
The CAR04 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
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.
How it fits
| Brand | Carlton |
|---|---|
| Colours | Black, Blue |
| Frame size | 52-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 CAR04
Choose the lens type that suits how you use your glasses:
- Progressive lenses for clear vision at every distance without swapping pairs.
- Single vision for one job done well: driving, reading or desk work.
- Bifocal if you like a clearly marked reading section.
- Ready readers when you only need help close up.
The 38mm lens depth gives progressive lenses plenty of room. If your prescription is on the stronger side, a thinner high-index lens keeps the edges neat, and an anti-reflective coating means fewer distracting reflections on screens and at night.
Ordering online is easier than you think
All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.
How your glasses are made
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your CAR04 and then sends your glasses to you in Australia.
Looking after them
Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
Your questions, answered
Can I get progressive lenses in the CAR04?
Yes. The 38mm lens depth gives progressive lenses enough height for all three vision zones.
Is the CAR04 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 52-17-140: 52mm 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.
