Colt 3538

Colt 3538 Prescription Glasses

Rectangular frames are the dependable all-rounders of eyewear. 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, varifocal or bifocal lenses made to your prescription. You will find it in our Colt range.

Gunmetal/silver or Navy/Gunmetal: which one is you?

Gunmetal/silver. Gunmetal/silver pairs gunmetal with silver. It is cool, modern and understated, and it suits grey or silver hair especially well.

Navy/Gunmetal. Navy/Gunmetal pairs navy with gunmetal. It is a quiet, professional finish that works with navy, charcoal and white.

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

Design 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 3538 an easy pick for everyday wear.

How to wear it

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.

How it fits

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.

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 3538

Your optician’s prescription will usually tell you which of these you need:

• 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 37mm lens depth works with single vision, bifocal and many varifocal lenses. If your prescription is high, a high-index lens keeps things thin. An anti-reflective, scratch-resistant coating is a sensible extra for everyday wear. Spend a lot of time on screens? This frame is also part of our blue light glasses range.

Ordering online is simple

You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.

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 3538. Every pair is checked before it leaves us.

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.
