About the Solo 234
Solo 234 Prescription Glasses
Some frames just suit almost everyone. Rounded squares are high on that list. The Solo 234 is a unisex full-rim metal rounded square frame, sized 51-16-135, in Gold, Blue or Dark Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Solo range.
Choosing your Solo 234 colour
Gold. Gold is a warm, soft gold. It brings warmth to the face and looks lovely with gold jewellery or a watch.
Blue. The Blue version is navy. It looks great with blue or grey eyes and pairs easily with denim and white.
Dark Purple. Dark Purple is a good everyday shade. It adds a confident touch of colour and suits fair and cool skin tones.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Design details
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces. Metal lets the frame stay slim and light while keeping its shape.
If you want a frame you can put on in the morning and forget about, the Solo 234 is a strong choice.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Gold, Blue, Dark Purple |
| Frame size | 51-16-135 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
The 51mm lenses make this a medium frame that suits most faces. The 16mm bridge is on the narrow side. The 135mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the Solo 234
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 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.
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 234. Every pair is checked before it leaves us.
A little care goes a long way
Clean your lenses with a microfibre cloth rather than your jumper, keep them in their case when they are in your bag, and do not leave them on a sunny car dashboard. Our lens care guide has more tips.
Your questions, answered
Can I get varifocal lenses in the Solo 234?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Solo 234 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-16-135: 51mm lens width, 16mm bridge and 135mm 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.
