About the Solo 843
Solo 843 Prescription Glasses
If you like structure but not sharp angles, a soft square is the sweet spot. The Solo 843 is a unisex full-rim soft square frame, sized 54-15-145, in Black, Champagne or Havana. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo collection.
Which colour is you?
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Champagne. The Champagne version is champagne crystal. It is a fresh, modern choice that suits almost any skin tone.
Havana. In Havana, the frame is tortoiseshell. It flatters warm and olive skin and works with almost any outfit.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Why you will like it
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. The crystal finish is clear and fresh, and it lets your features take centre stage.
The Solo 843 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Wearing it every day
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
How it fits
| Brand | Solo |
|---|---|
| Colours | Black, Champagne, Havana |
| Frame size | 54-15-145 mm (lens width, bridge, arm length) |
| Lens depth | 45 mm |
The 54mm lenses put it at the upper end of medium. The 15mm bridge is narrow, so it sits securely on a slimmer nose. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 123mm.
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 Solo 843
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.
At 45mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. 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.
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
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Solo 843. Every pair is checked before it leaves us.
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.
FAQs
Can I get varifocal lenses in the Solo 843?
Yes. The 45mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Solo 843 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 size is it?
It is size 54-15-145: 54mm lens width, 15mm bridge and 145mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 15mm bridge is designed for slimmer noses.
What does crystal mean?
A clear, see-through 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.
