About the Solo 592
Solo 592 Prescription Glasses
Round glasses have a quiet, clever charm that never really goes out of style. The Solo 592 is a unisex full-rim round frame, sized 48-20-140, in Black or Demi. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo range.
Black or Demi?
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Demi. The Demi version is tortoiseshell. It warms up the face and sits nicely alongside camel, olive and cream.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
The details
Round frames soften angular features, so they are a great match for square and heart-shaped faces.
It is the kind of frame that works with most outfits, which makes the Solo 592 an easy pick for everyday wear.
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 | 48-20-140 mm (lens width, bridge, arm length) |
| Lens depth | 40 mm |
With 48mm lenses, this is a compact frame that suits smaller faces. The 20mm bridge is wider than average, which suits a broader nose bridge. The 140mm arms are a standard length. Across the lenses and bridge it measures about 116mm.
The easiest way to check is against glasses you already love. Most frames show their size inside the arm; if yours are close to these, you are in safe territory.
Lens options for the Solo 592
Your optician’s prescription will usually tell you which of these you need:
- Varifocals if you want to see near and far without swapping glasses.
- Single vision for one task done well, such as driving, reading or screen work.
- Bifocals if you prefer a clearly defined reading area.
- Ready readers for straightforward close-up help.
The 40mm 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.
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
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Solo 592 and checked by our technicians before they are sent out.
Looking after them
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 592?
Yes. The 40mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the Solo 592 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 small frame?
Yes. With 48mm lenses it suits smaller faces.
Will it suit a wider nose bridge?
Yes. The 20mm bridge is wider than most frames.
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.
