About the Solo 590
Solo 590 Prescription Glasses
Round glasses have a quiet, clever charm that never really goes out of style. The Solo 590 is a unisex full-rim round frame, sized 47-19-140, in Black or Demi. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Solo range.
Black or Demi: which one is you?
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Demi. In Demi, the frame is brown tortoiseshell. It is a classic that looks relaxed and a little bit vintage.
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.
The details
Round frames soften angular features, so they are a great match for square and heart-shaped faces.
If you want a frame you can put on in the morning and forget about, the Solo 590 is a strong choice.
Wearing it every day
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, Demi |
| Frame size | 47-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
With 47mm lenses, this is a compact frame that suits smaller faces. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 113mm.
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 590
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.
The 38mm lens depth gives varifocal lenses plenty 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.
From our lab to you
Your Solo 590 is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.
Looking after them
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 590?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Solo 590 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a small frame?
Yes. With 47mm lenses it suits smaller faces.
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear finish.
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.
