About the LK Bennett L.K.Bennett 81
L.K.Bennett 81 Prescription Glasses
Cat-eye frames manage to look glamorous and practical at the same time. 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, varifocal or bifocal lenses made to your prescription. It is part of our LK Bennett range.
Which colour is you?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Blue. Blue is a clear, easy-to-wear blue. It looks great with blue or grey eyes and pairs easily with denim and white.
Tort. In Tort, the frame is tortoiseshell. It flatters warm and olive skin and works with almost any outfit.
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.
The details
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. Tortoiseshell arms add warmth and a classic finishing touch.
It is the kind of frame that works with most outfits, which makes the L.K.Bennett 81 an easy pick for everyday wear. Thinking of a second pair? The L.K.Bennett 81 works well as a backup.
Wearing it every day
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.
How it fits
| Brand | LK Bennett |
|---|---|
| Frame | Full Rim |
| Colours | Black, Blue, Tort |
| Frame size | 50-16-140 mm (lens width, bridge, arm length) |
| Designed for | Women |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 116mm.
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 L.K.Bennett 81
Choose the lens type that suits how you use your glasses:
- 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.
With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.
What you will need
Have your prescription to hand before you start. It shows the sphere, cylinder and axis for each eye, and sometimes your PD. If the PD is missing, your optician can give it to you. Then choose your colour and lens type, enter your prescription and add any extras, such as thinner lenses or a coating. You can check everything in your basket before you pay.
Made for you in our UK lab
Your L.K.Bennett 81 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.
Keep them looking new
Clean your lenses with a microfibre cloth rather than your jumper, keep them in their case when they are in your bag, and do not leave them on a sunny car dashboard. Our lens care guide has more tips.
Your questions, answered
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
Is the L.K.Bennett 81 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.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
