About the Solo 842
Solo 842 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The Solo 842 is a unisex full-rim rectangular frame, sized 55-18-140, in Blue, Grey or Crystal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Solo collection.
3 colours to choose from
Blue. In Blue, the frame is navy. It brings a cool, calm touch of colour that suits most skin tones.
Grey. Grey is a soft, neutral grey. It is cool, modern and understated, and it suits grey or silver hair especially well.
Crystal. In Crystal, the frame is crystal clear. It is a fresh, modern choice that suits almost any skin tone.
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. A crystal front looks modern and light, and it goes with everything.
If you want a frame you can put on in the morning and forget about, the Solo 842 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.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Blue, Grey, Crystal |
| Frame size | 55-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
At 55mm per lens, it is a generous size, a good pick if standard frames feel tight. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 128mm.
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 842
Your optician’s prescription will usually tell you which of these you need:
- Single vision: one prescription across the whole lens, for distance, reading or the computer.
- Varifocal: near, intermediate and distance in one lens, with no visible line.
- Bifocal: a separate reading segment in the lower part of the lens.
- Ready readers: simple magnification if you just need help with close work.
The 36mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
From our lab to you
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Solo 842 and checked by our technicians before they are sent out.
Looking after them
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.
FAQs
Can I get varifocal lenses in the Solo 842?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the Solo 842 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.
Is it a large frame?
Yes. With 55mm lenses it suits wider faces.
What does crystal mean?
A clear, see-through 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.
