About the Solo 852
Solo 852 Prescription Glasses
Square frames have a confident, modern look that works almost anywhere. The Solo 852 is a unisex full-rim square frame, sized 53-17-140, in Black, Dark Purple, Green or Red. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo collection.
4 colours to choose from
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Dark Purple. The Dark Purple version is patterned purple. It is softer than it sounds and looks lovely with grey or silver hair.
Green. In Green, the frame is patterned green. It is unusual without being loud, and it looks fantastic with red, auburn or dark hair.
Red. The Red version is patterned 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
Square lenses add structure to round and oval faces and make features look more defined. The patterned finish means no two angles look quite the same.
If you want a frame you can put on in the morning and forget about, the Solo 852 is a strong choice.
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, Dark Purple, Green, Red |
| Frame size | 53-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
At 53mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 123mm.
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 852
Choose the lens type that suits how you use your glasses:
- 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.
At 41mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. 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.
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.
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 852 and checked by our technicians before they are sent out.
Keep them looking new
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.
Your questions, answered
Can I get varifocal lenses in the Solo 852?
Yes. The 41mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the Solo 852 as computer glasses?
Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both work well for desk work.
What size is it?
It is size 53-17-140: 53mm lens width, 17mm bridge and 140mm arms, a medium fit.
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.
