About the Carducci CD7173
CD7173 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The CD7173 is a unisex full-rim metal rectangular frame, sized 51-17-135, in Black. You can order it with single vision, progressive or bifocal lenses made to your prescription. It belongs to the Carducci collection.
The colour
Black. In Black, the frame is black and silver. It defines the eyes and goes with every outfit you own.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. Metal lets the frame stay slim and light while keeping its shape.
Whether it is your main pair or a spare, the CD7173 is easy to live with.
Styling tips
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Carducci |
|---|---|
| Colours | Black |
| Frame size | 51-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 35 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 135mm 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 CD7173
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 35mm lens depth works with single vision, bifocal and many progressive lenses. Stronger prescription? A high-index lens keeps things thin and light. An anti-reflective, scratch-resistant coating is worth adding too, especially if you drive 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 CD7173 and then sends your glasses to you in Australia.
Keep them looking new
Clean the lenses with lens spray and a soft cloth, fold the arms before you put them down, and keep them in a hard case when they are not on your face. Our guide to caring for your lenses covers the rest.
A second pair?
Plenty of people keep more than one pair of glasses: one for work, one for home, or a spare in the car. A second pair also means you are never stuck if your main glasses are being repaired. This frame is an easy choice for either role.
Questions we often get
Can I get progressive lenses in the CD7173?
Yes. The 35mm lens depth gives progressive lenses enough height for all three vision zones.
Is the CD7173 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 51-17-135: 51mm lens width, 17mm bridge and 135mm arms, a medium fit.
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.
