Colt 3547

Colt 3547 Prescription Glasses

A clean rectangular frame works at the office, at home and everywhere in between. The Colt 3547 is a men’s full-rim plastic rectangular frame, sized 55-17-145, in Black or Grey. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Colt range.

Choosing your Colt 3547 colour

Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.

Grey. Grey is a soft, neutral grey. It is a quiet, professional finish that works with navy, charcoal and white.

Each colour is shown in the gallery, so you can compare them side by side before you decide.

Shape and style

Rectangular lenses suit round and oval faces, adding a bit of definition. Plastic keeps the weight down and allows richer, deeper colour than metal.

It is the kind of frame that works with most outfits, which makes the Colt 3547 an easy pick for everyday wear.

How to wear it

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

With 55mm lenses, this is a larger frame that suits wider faces. 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 127mm.

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 3547

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

• Single vision: the same prescription from edge to edge.
• Bifocal: distance at the top and a reading segment at the bottom.
• Varifocal: a smooth change from distance to reading, with no line.
• Ready readers: a fixed magnification for books, phones and screens.

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.

Before you order

Make sure your prescription is in date; most adults in the UK are advised to have an eye test every two years, and your optician will tell you if you need one sooner. You will also need your PD, which tells our lab where to centre the lenses. With those two things ready, ordering takes a few minutes: choose your colour, pick your lenses, enter your details and you are done.

Made for you in our UK lab

Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Colt 3547. Every pair is checked before it leaves us.

Looking after them

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.

Your questions, answered

Can I get varifocal lenses in the Colt 3547?

Yes. The 39mm lens depth gives varifocal lenses enough height for all three vision zones.

Can I use the Colt 3547 as computer glasses?

Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both work well for desk work.

Is it a large frame?

Yes. With 55mm lenses it suits wider faces.

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.
