About the Solo 564
Solo 564 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The Solo 564 is a unisex full-rim metal rectangular frame, sized 51-18-140, in Silver, Black or Gun Metal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Solo range.
Which colour is you?
Silver. Silver is a clean, bright silver. It is cool, modern and understated, and it suits grey or silver hair especially well.
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Gun Metal. The Gun Metal version is gunmetal. It is a great match for cooler skin tones and a crisp, tidy look.
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.
About the Solo 564 design
Rectangular lenses suit round and oval faces, adding a bit of definition. A crystal front looks modern and light, and it goes with everything.
A patterned front adds personality while still being easy to wear. Metal lets the frame stay slim and light while keeping its shape.
It is the kind of frame that works with most outfits, which makes the Solo 564 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.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Silver, Black, Gun Metal |
| Frame size | 51-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 30 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.
Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.
Lens options for the Solo 564
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 30mm 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.
Ordering online is simple
You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.
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 564 and checked by our technicians before they are sent out.
A little care goes a long way
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 564 suitable for varifocals?
The 30mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I use the Solo 564 as computer glasses?
Yes. Single vision lenses set to your screen distance work well for desk work.
What size is it?
It is size 51-18-140: 51mm lens width, 18mm bridge and 140mm arms, a medium fit.
What does crystal mean?
A clear, see-through 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.
