About the Colt 3542
Colt 3542 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The Colt 3542 is a men’s full-rim plastic rectangular frame, sized 59-18-150, in Black or Grey. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Colt collection.
Black or Grey?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Grey. In Grey, the frame is striped grey. It is cool, modern and understated, and it suits grey or silver hair especially well.
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.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition. Layered stripes of colour give the frame movement and a natural, horn-like depth.
Plastic keeps the weight down and allows richer, deeper colour than metal.
If you want a frame you can put on in the morning and forget about, the Colt 3542 is a strong choice.
Wearing it every day
It looks sharp with a collared shirt and works just as well with a T-shirt. If you have a beard, a slightly bolder frame balances the face nicely.
Frame size and fit
| Brand | Colt |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Black, Grey |
| Frame size | 59-18-150 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
| Designed for | Men |
With 59mm 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 136mm.
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 Colt 3542
Pick the lenses that match your prescription:
- Single vision: one prescription for distance, reading or the computer.
- Progressive: near, middle and far in one lens with no line. (In the UK they call them varifocals.)
- Bifocal: a defined reading area at the bottom of the lens.
- Ready readers: simple magnification for close work.
At 41mm, the lens depth is deeper than most frames in our range, so progressive lenses have lots 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
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 Colt 3542 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 Colt 3542?
Yes. The 41mm lens depth gives progressive lenses enough height for all three vision zones.
Is the Colt 3542 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 59mm 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.
