About the Carlton CAR30
CAR30 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The CAR30 is a unisex full-rim rectangular frame, sized 50-19-142, in Black Crystal. You can order it with single vision, progressive or bifocal lenses made to your prescription. It is part of our Carlton collection.
The colour
Black Crystal. The Black Crystal version is black and crystal. It looks sharp at work and just as good with jeans at the weekend.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition. The crystal finish is clear and fresh, and it lets your features take centre stage.
The CAR30 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Carlton |
|---|---|
| Colours | Black Crystal |
| Frame size | 50-19-142 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 19mm bridge is a little wider than average. The 142mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
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 CAR30
Choose the lens type that suits how you use your glasses:
- Single vision: one clear prescription across the whole lens.
- Bifocal: distance on top, a reading segment below.
- Progressive: smooth vision from near to far in one lens, no line.
- Ready readers: off-the-shelf magnification for books and screens.
The 39mm lens depth gives progressive lenses plenty of room. Prefer to keep things slim? Choose a high-index lens, which is thinner and lighter than standard. Then add an anti-reflective coating to cut glare from headlights and screens.
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.
Made for you in our UK lab
Choose your colour and lenses, enter your prescription and PD, and our optical lab in the UK makes your lenses and fits them into your CAR30 before sending them to you in Australia.
A little care goes a long way
Wipe your lenses with a microfibre cloth rather than the hem of your shirt, keep them in a case when they are in your bag, and never leave them on the dashboard on a hot day. Our lens care guide has a few more habits worth picking up.
Your questions, answered
Can I get progressive lenses in the CAR30?
Yes. The 39mm lens depth gives progressive lenses enough height for all three vision zones.
Can I wear the CAR30 for driving?
Yes. Single vision or progressive 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 then sent to you in Australia.
