About the Carlton CAR37
CAR37 Prescription Glasses
A softly squared frame is one of the most versatile shapes around. The CAR37 is a unisex full-rim soft square frame, sized 49-18-140, in Black, Grey or Crystal. You can order it with single vision, progressive or bifocal lenses made to your prescription. It belongs to the Carlton range.
Which colour is you?
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Grey. The Grey version is translucent grey. It is a quiet, professional finish that works with navy, charcoal and white.
Crystal. In Crystal, the frame is crystal clear. It blends in rather than stands out, which many people find easy to wear every day.
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.
Shape and style
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. The crystal finish is clear and fresh, and it lets your features take centre stage.
Because the colour is see-through, the frame has a light, glowing look.
It is the kind of frame that works with most outfits, which makes the CAR37 an easy pick for everyday wear.
How to wear it
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, Grey, Crystal |
| Frame size | 49-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
At 49mm 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 116mm.
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 CAR37
Pick the lenses that match your prescription:
- 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 39mm 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.
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
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your CAR37 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.
FAQs
Can I get progressive lenses in the CAR37?
Yes. The 39mm lens depth gives progressive lenses enough height for all three vision zones.
Can I use the CAR37 as computer glasses?
Yes. Single vision lenses set to your screen distance, or progressive lenses if you also need distance vision, both work well for desk work.
Is it a small frame?
Yes. With 49mm lenses it suits smaller faces.
What does crystal mean?
A clear, see-through finish.
Do you make the lenses yourselves?
Yes. Every pair is made to order in our UK optical lab, where your lenses are cut to your prescription and fitted into your frame.
