About the Walter & Herbert Blackwell
Blackwell Prescription Glasses
Cat-eye frames manage to look glamorous and practical at the same time. The Blackwell is a women’s full-rim cat-eye frame, sized 51-16-140, in Red, Teal or Tort. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Walter & Herbert range.
Which colour is you?
Red. Red is a confident red. It looks great with neutral outfits and a bold lip.
Teal. Teal is a blue-green teal. It brings out brown, hazel and green eyes.
Tort. The Tort version is tortoiseshell. It is a classic that looks relaxed and a little bit vintage.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
The details
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. The fine metal arms keep the weight down and look neat from the side.
If you want a frame you can put on in the morning and forget about, the Blackwell is a strong choice. The Blackwell also makes a handy spare pair for the car or the office.
How to wear it
Pair it with simple gold or silver earrings and let the frame do the rest. If you wear your hair up, a frame like this can act as your main accessory.
Size and fit
| Brand | Walter & Herbert |
|---|---|
| Frame | Full Rim |
| Colours | Red, Teal, Tort |
| Frame size | 51-16-140 mm (lens width, bridge, arm length) |
| Designed for | Women |
The 51mm lenses make this a medium frame that suits most faces. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
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 Blackwell
Pick the lenses that match your prescription:
- 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.
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.
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
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Blackwell and checked by our technicians before they are sent out.
Keep them looking new
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
What size is it?
It is size 51-16-140: 51mm lens width, 16mm bridge and 140mm arms, a medium fit.
Is the Blackwell 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.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear finish.
Where are my lenses made?
In our UK optical lab. They are cut to your prescription, fitted into your frame and checked before they are sent out.
