About the Colt 3538
Colt 3538 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The Colt 3538 is a men’s full-rim titanium rectangular frame, sized 59-17-150, in Gunmetal/silver or Navy/Gunmetal. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Colt collection.
Gunmetal/silver or Navy/Gunmetal: which one is you?
Gunmetal/silver. Gunmetal/silver mixes gunmetal and silver. It is a great match for cooler skin tones and a crisp, tidy look.
Navy/Gunmetal. Navy/Gunmetal mixes navy and gunmetal. It goes with almost everything and never draws too much attention.
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
Rectangular lenses suit round and oval faces, adding a bit of definition. Titanium is one of the lightest frame materials around, which makes it a great choice for all-day wear.
It is the kind of frame that works with most outfits, which makes the Colt 3538 an easy pick for everyday wear.
Styling tips
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.
How it fits
| Brand | Colt |
|---|---|
| Frame | Full Rim, Titanium |
| Colours | Gunmetal/silver, Navy/Gunmetal |
| Frame size | 59-17-150 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
| Designed for | Men |
With 59mm lenses, this is a larger frame that suits wider faces. The 17mm bridge is average. The 150mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 135mm.
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 Colt 3538
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.
The 37mm 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. Spend a lot of time on screens? This frame is also part of our blue light glasses range.
What you need to order
Have your prescription handy before you start. It will list the sphere, cylinder and axis for each eye, and often your PD as well. If your PD is missing, your optometrist can give it to you. Then simply choose your colour and lens type, enter your prescription and add any extras, such as a thinner lens or a coating. You can review everything in your cart before you pay.
Made for you in our UK lab
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 Colt 3538 and sends the finished pair to you in Australia.
Looking after them
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.
Questions we often get
Can I get progressive lenses in the Colt 3538?
Yes. The 37mm lens depth gives progressive lenses enough height for all three vision zones.
Is the Colt 3538 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.
