About the Solo 073
Solo 073 Prescription Glasses
If round and square both feel too ordinary, try a geometric shape. The Solo 073 is a unisex full-rim metal geometric frame, sized 50-18-140, in Black or Dark Gun. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Solo range.
Choosing your Solo 073 colour
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Dark Gun. The Dark Gun version is gunmetal. It is a great match for cooler skin tones and a crisp, tidy look.
Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.
Shape and style
The angular shape suits round and oval faces, where it adds definition and interest. Being semi-rimless, it keeps a defined top line while the lower half of the lens stays open and light.
Metal lets the frame stay slim and light while keeping its shape.
Whether it is your main pair or a spare, the Solo 073 is easy to live with.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Solo |
|---|---|
| Colours | Black, Dark Gun |
| Frame size | 50-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 43 mm |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
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 073
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.
At 43mm, 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
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Solo 073. Every pair is checked before it leaves us.
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.
Your questions, answered
Can I get varifocal lenses in the Solo 073?
Yes. The 43mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 073 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.
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
What does semi-rimless mean?
The frame runs along the top of the lenses only. The lower edge is held by a fine line, so the bottom of the lens is open.
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.
