About the Solo 833
Solo 833 Prescription Glasses
A softly squared frame is one of the most versatile shapes around. The Solo 833 is a unisex full-rim soft square frame, sized 51-15-140, in Black, Havana or Wine. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo collection.
Choosing your Solo 833 colour
Black. Black is a deep, solid black. It is the safest choice if you only want one pair, and it never looks out of place.
Havana. In Havana, the frame is tortoiseshell. It is softer than black and suits brown, auburn and red hair.
Wine. Wine is a deep wine red. It is rich and confident, and it looks stunning with dark hair.
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 Solo 833 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Styling tips
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, Havana, Wine |
| Frame size | 51-15-140 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 15mm bridge is narrow, so it sits securely on a slimmer nose. The 140mm arms are a standard length. Across the lenses and bridge it measures about 117mm.
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 Solo 833
Pick the lenses that match your prescription:
- 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 38mm lens depth gives varifocal lenses plenty of room. 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.
Made for you in our UK lab
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Solo 833 and checked by our technicians before they are sent out.
Looking after them
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.
Your questions, answered
Can I get varifocal lenses in the Solo 833?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 833 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 51-15-140: 51mm lens width, 15mm bridge and 140mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 15mm 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.
