About the Walter & Herbert Cook
Cook Prescription Glasses
If round and square both feel too ordinary, try a geometric shape. The Cook is a men’s full-rim geometric frame, sized 49-20-145, in Black, Green or Tort. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Walter & Herbert range.
3 colours to choose from
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Green. In Green, the frame is translucent green. It feels fresh and a little bit different, which is exactly why people notice it.
Tort. In Tort, the frame is tortoiseshell. It is a classic that looks relaxed and a little bit vintage.
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
The angular shape suits round and oval faces, where it adds definition and interest. Because the colour is see-through, the frame has a light, glowing look.
The Cook is a great everyday frame: smart enough for work and relaxed enough for the weekend.
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 | Walter & Herbert |
|---|---|
| Frame | Full Rim |
| Colours | Black, Green, Tort |
| Frame size | 49-20-145 mm (lens width, bridge, arm length) |
| Designed for | Men |
At 49mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 20mm bridge is wider than average, which suits a broader nose bridge. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 118mm.
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 Cook
Your optician’s prescription will usually tell you which of these you need:
- Single vision: one prescription across the whole lens, for distance, reading or the computer.
- Varifocal: near, intermediate and distance in one lens, with no visible line.
- Bifocal: a separate reading segment in the lower part of the lens.
- Ready readers: simple magnification if you just need help with close work.
Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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.
From our lab to you
Your Cook is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.
A little care goes a long way
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
FAQs
Is it a small frame?
Yes. With 49mm lenses it suits smaller faces.
Can I wear the Cook for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Will it suit a wider nose bridge?
Yes. The 20mm bridge is wider than most frames.
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear finish.
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.
