About the Solo 031
Solo 031 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The Solo 031 is a unisex full-rim metal rectangular frame, sized 54-18-140, in Gold, Bronze or Gun Metal. 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?
Gold. Gold is a warm, soft gold. It brings warmth to the face and looks lovely with gold jewellery or a watch.
Bronze. Bronze is a warm, brownish metallic finish. It brings warmth to the face and looks lovely with gold jewellery or a watch.
Gun Metal. The Gun Metal version is gunmetal. It is a quiet, professional finish that works with navy, charcoal and white.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
The details
Rectangular lenses suit round and oval faces, adding a bit of definition. The slim metal construction keeps it light and neat, and it is easy for an optician to adjust.
It is the kind of frame that works with most outfits, which makes the Solo 031 an easy pick for everyday wear.
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.
Frame size and fit
| Brand | Solo |
|---|---|
| Colours | Gold, Bronze, Gun Metal |
| Frame size | 54-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 33 mm |
The 54mm lenses put it at the upper end of medium. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 126mm.
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 031
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.
The 33mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
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.
From our lab to you
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Solo 031. Every pair is checked before it leaves us.
Keep them looking new
Rinse off any grit before you wipe, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay aligned. See our lens care guide for more.
FAQs
Is the Solo 031 suitable for varifocals?
The 33mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Is the Solo 031 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.
What size is it?
It is size 54-18-140: 54mm lens width, 18mm bridge and 140mm arms, a medium fit.
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.
