About the LK Bennett L.K.Bennett 78
L.K.Bennett 78 Prescription Glasses
A browline frame always looks a little bit clever. The L.K.Bennett 78 is a women’s browline frame, sized 52-17-135, in Beige, Blue or Burgundy. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our LK Bennett range.
Which colour is you?
Beige. Beige is a soft, light beige. It blends in rather than stands out, which many people find easy to wear every day.
Blue. Blue is a clear, easy-to-wear blue. It looks great with blue or grey eyes and pairs easily with denim and white.
Burgundy. Burgundy is a deep wine red. It adds warmth without being too bright, and it suits most skin tones.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
The details
The stronger top line suits round, oval and heart-shaped faces, and it can make you look more awake. The frame runs along the top of the lenses only, so the lower edge is open and your view stays clear.
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 78 an easy pick for everyday wear.
How to wear it
For work, pair it with a crisp shirt or blazer. At the weekend it looks just as good with a T-shirt and jeans.
Size and fit
| Brand | LK Bennett |
|---|---|
| Frame | Semi-rimless |
| Colours | Beige, Blue, Burgundy |
| Frame size | 52-17-135 mm (lens width, bridge, arm length) |
| Designed for | Women |
The 52mm lenses make this a medium frame that suits most faces. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 L.K.Bennett 78
Your optician’s prescription will usually tell you which of these you need:
- 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.
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 L.K.Bennett 78 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
What size is it?
It is size 52-17-135: 52mm lens width, 17mm bridge and 135mm arms, a medium fit.
Can I wear the L.K.Bennett 78 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What does semi-rimless mean?
The frame runs along the top of the lenses only. The lower edge is held by a fine line, so the bottom of the lens is open.
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.
