About the Carlton CAR40
CAR40 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The CAR40 is a unisex full-rim rectangular frame, sized 58-18-150, in Black, Blue or Grey. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Carlton collection.
Choosing your CAR40 colour
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.
Blue. The Blue version is navy. It looks great with blue or grey eyes and pairs easily with denim and white.
Grey. In Grey, the frame is translucent grey. 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.
About the CAR40 design
Rectangular lenses suit round and oval faces, adding a bit of definition. Because the colour is see-through, the frame has a light, glowing look.
The CAR40 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
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.
Frame size and fit
| Brand | Carlton |
|---|---|
| Colours | Black, Blue, Grey |
| Frame size | 58-18-150 mm (lens width, bridge, arm length) |
| Lens depth | 40 mm |
With 58mm lenses, this is a larger frame that suits wider faces. The 18mm bridge is average. The 150mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 134mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the CAR40
Your optometrist’s prescription will usually tell you which of these you need:
- 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 40mm 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.
Before you order
Check that your prescription is current; an eye test every couple of years is a good habit, and your optometrist will tell you how often you need one. You will also need your PD, which tells the lab where to centre the lenses so you look through the right spot. With those two things in hand, ordering takes just a few minutes: choose your colour, pick your lenses, enter your details and you are done.
How your glasses are made
Once you have picked your colour and lens type and entered your prescription and PD, our UK optical lab makes your lenses, fits them into your CAR40 and sends the finished pair 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 CAR40?
Yes. The 40mm lens depth gives progressive lenses enough height for all three vision zones.
Is the CAR40 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.
Is it a large frame?
Yes. With 58mm lenses it suits wider faces.
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.
