Colt 3544

Colt 3544 Prescription Glasses

A clean rectangular frame works at the office, at home and everywhere in between. The Colt 3544 is a men’s full-rim titanium rectangular frame, sized 56-17-145, in Black or Gunmetal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Colt collection.

Black or Gunmetal?

Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.

Gunmetal. Gunmetal is a dark, smoky grey metal. It is a great match for cooler skin tones and a crisp, tidy look.

If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.

The details

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 3544 an easy pick for everyday wear.

Wearing it every day

Choose the darker colour for the office and the lighter one for a more relaxed look. Either way, it is an easy frame to wear every day.

Frame size and fit

At 56mm per lens, it is a generous size, a good pick if standard frames feel tight. The 17mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 129mm.

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 Colt 3544

Choose the lens type that suits how you use your glasses:

• Varifocals if you want to see near and far without swapping glasses.
• Single vision for one task done well, such as driving, reading or screen work.
• Bifocals if you prefer a clearly defined reading area.
• Ready readers for straightforward close-up help.

The 39mm lens depth gives varifocal lenses plenty of room. With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.

What you will need

Have your prescription to hand before you start. It shows the sphere, cylinder and axis for each eye, and sometimes your PD. If the PD is missing, your optician can give it to you. Then choose your colour and lens type, enter your prescription and add any extras, such as thinner lenses or a coating. You can check everything in your basket before you pay.

Made for you in our UK lab

Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Colt 3544 and checked by our technicians before they are sent out.

Keep them looking new

Rinse off any grit before you wipe, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay aligned. See our lens care guide for more.
