About the Solo 580
Solo 580 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The Solo 580 is a unisex full-rim rectangular frame, sized 51-18-140, in Black, Havana or Purple Demi. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Solo collection.
3 colours to choose from
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Havana. The Havana version is tortoiseshell. It is a classic that looks relaxed and a little bit vintage.
Purple Demi. Purple Demi is a good everyday shade. 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.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition.
The Solo 580 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
How to wear it
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, Havana, Purple Demi |
| Frame size | 51-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 120mm.
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 580
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 39mm 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.
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 580. Every pair is checked before it leaves us.
Looking after them
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
Questions we often get
Can I get varifocal lenses in the Solo 580?
Yes. The 39mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Solo 580 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-18-140: 51mm lens width, 18mm bridge and 140mm arms, a medium fit.
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear 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.
