About the Solo 837
Solo 837 Prescription Glasses
A softly squared frame is one of the most versatile shapes around. The Solo 837 is a unisex full-rim soft square frame, sized 52-16-140, in Blue, Brown or Dark Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Solo collection.
Which colour is you?
Blue. In Blue, the frame is patterned blue. It looks great with blue or grey eyes and pairs easily with denim and white.
Brown. Brown is a warm, earthy brown. It is a classic that looks relaxed and a little bit vintage.
Dark Purple. In Dark Purple, the frame is patterned purple. It brings a little personality without overpowering your features.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. The patterned finish means no two angles look quite the same.
Whether it is your main pair or a spare, the Solo 837 is easy to live with.
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 | Blue, Brown, Dark Purple |
| Frame size | 52-16-140 mm (lens width, bridge, arm length) |
| Lens depth | 34 mm |
The 52mm lenses make this a medium frame that suits most faces. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 120mm.
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 837
Your optician’s prescription will usually tell you which of these you need:
- Single vision: the same prescription from edge to edge.
- Bifocal: distance at the top and a reading segment at the bottom.
- Varifocal: a smooth change from distance to reading, with no line.
- Ready readers: a fixed magnification for books, phones and screens.
The 34mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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.
How your glasses are made
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Solo 837 and checked by our technicians before they are sent out.
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.
Questions we often get
Is the Solo 837 suitable for varifocals?
The 34mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Is the Solo 837 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 52-16-140: 52mm lens width, 16mm bridge and 140mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
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.
