About the Solo 584
Solo 584 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Solo 584 is a unisex full-rim rectangular frame in Black, Black/Purple or Demi. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Solo range.
3 colours to choose from
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Black/Purple. The Black/Purple version is black and purple. It defines the eyes and goes with every outfit you own.
Demi. The Demi version is tortoiseshell. It is softer than black and suits brown, auburn and red hair.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
About the Solo 584 design
Rectangular lenses suit round and oval faces, adding a bit of definition.
The Solo 584 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
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, Black/Purple, Demi |
| Lens depth | 38 mm |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 16mm bridge is on the narrow side. Across the lenses and bridge it measures about 120mm.
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 584
Pick the lenses that match your prescription:
- 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. With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.
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
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Solo 584. 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.
Questions we often get
Can I get varifocal lenses in the Solo 584?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 584 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.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear finish.
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.
