About the LK Bennett L.K.Bennett 81
L.K.Bennett 81 Prescription Glasses
A cat-eye is one of the most flattering shapes you can wear. The L.K.Bennett 81 is a women’s full-rim cat-eye frame, sized 50-16-140, in Black, Blue or Tort. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our LK Bennett range.
Choosing your L.K.Bennett 81 colour
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Blue. Blue is a clear, easy-to-wear blue. It is a fresh alternative to black that still looks professional.
Tort. In Tort, the frame is tortoiseshell. It warms up the face and sits nicely alongside camel, olive and cream.
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.
About the L.K.Bennett 81 design
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. The tortoiseshell arms pair nicely with the front and give the frame a relaxed feel.
Whether it is your main pair or a spare, the L.K.Bennett 81 is easy to live with.
How to wear it
Match the frame colour to something you wear often, such as a favourite scarf or bag, for a pulled-together look. Neutral make-up keeps the focus on your eyes.
Frame size and fit
| Brand | LK Bennett |
|---|---|
| Frame | Full Rim |
| Colours | Black, Blue, Tort |
| Frame size | 50-16-140 mm (lens width, bridge, arm length) |
| Designed for | Women |
With 50mm lenses, this is a compact frame that suits smaller faces. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 116mm.
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 L.K.Bennett 81
Your optometrist’s prescription will usually tell you which of these you need:
- 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.
If your prescription is on the stronger side, a thinner high-index lens keeps the edges neat, and an anti-reflective coating means fewer distracting reflections on screens and at night.
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.
Made for you in our UK lab
Choose your colour and lenses, enter your prescription and PD, and our optical lab in the UK makes your lenses and fits them into your L.K.Bennett 81 before sending them to you in Australia.
A little care goes a long way
Clean the lenses with lens spray and a soft cloth, fold the arms before you put them down, and keep them in a hard case when they are not on your face. Our guide to caring for your lenses covers the rest.
FAQs
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
Can I use the L.K.Bennett 81 as computer glasses?
Yes. Single vision lenses set to your screen distance, or progressive lenses if you also need distance vision, both work well for desk work.
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.
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.
