About the Walter & Herbert Darwin
Darwin Prescription Glasses
If you like structure but not sharp angles, a soft square is the sweet spot. The Darwin is a men’s full-rim soft square frame, sized 51-18-145, in Arctic Storm, Burnt Ember or Olive Topaz. You can order it with single vision, progressive or bifocal lenses made to your prescription. It belongs to the Walter & Herbert collection.
Which colour is you?
Arctic Storm. Arctic Storm is a good everyday shade. It is a versatile choice that works for most people.
Burnt Ember. Burnt Ember keeps things simple. It is a classic option that goes with almost anything.
Olive Topaz. Olive Topaz is a good everyday shade. It is unusual without being loud, and it looks fantastic with red, auburn or dark hair.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. The striped finish adds texture that changes as the light catches it.
Whether it is your main pair or a spare, the Darwin is easy to live with. For a frame you will reach for daily, the Darwin is a solid choice.
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
| Brand | Walter & Herbert |
|---|---|
| Frame | Full Rim |
| Colours | Arctic Storm, Burnt Ember, Olive Topaz |
| Frame size | 51-18-145 mm (lens width, bridge, arm length) |
| Designed for | Men |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 120mm.
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 Darwin
Choose the lens type that suits how you use your glasses:
- 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.
Prefer to keep things slim? Choose a high-index lens, which is thinner and lighter than standard. Then add an anti-reflective coating to cut glare from headlights and screens.
Ordering online is easier than you think
All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.
How your glasses are made
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Darwin and then sends your glasses to you in Australia.
Keep them looking new
Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
FAQs

Is the Darwin 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.
