About the Solo 599
Solo 599 Prescription Glasses
Soft corners take the edge off a square shape and make it easy to wear every day. The Solo 599 is a unisex full-rim soft square frame, sized 51-15-140, in Black/Cream. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Solo collection.
Colour and finish
Black/Cream. Black/Cream pairs black with cream. Black suits every hair colour and frames the face with confidence.
Why you will like it
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. A crystal front looks modern and light, and it goes with everything.
The Solo 599 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.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Black/Cream |
| Frame size | 51-15-140 mm (lens width, bridge, arm length) |
| Lens depth | 34 mm |
The 51mm lenses make this a medium frame that suits most faces. The 15mm bridge is narrow, so it sits securely on a slimmer nose. The 140mm arms are a standard length. Across the lenses and bridge it measures about 117mm.
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 599
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 34mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
Made for you in our UK lab
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Solo 599. Every pair is checked before it leaves us.
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.
FAQs
Is the Solo 599 suitable for varifocals?
The 34mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I wear the Solo 599 for driving?
Yes. Single vision lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-15-140: 51mm lens width, 15mm bridge and 140mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 15mm bridge is designed for slimmer noses.
What does crystal mean?
A clear, see-through finish.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
