About the Solo 818
Solo 818 Prescription Glasses
Soft corners take the edge off a square shape and make it easy to wear every day. The Solo 818 is a unisex full-rim soft square frame, sized 51-17-140, in Black, Burgundy, Dark Purple or Green. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Solo range.
Which colour is you?
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Burgundy. Burgundy is a deep wine red. It looks great with neutral outfits and a bold lip.
Dark Purple. In Dark Purple, the frame is black and purple. It is softer than it sounds and looks lovely with grey or silver hair.
Green. The Green version is black and green. It brings out brown, hazel and green eyes.
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 818 design
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe.
It is the kind of frame that works with most outfits, which makes the Solo 818 an easy pick for everyday wear.
Styling tips
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.
Frame size and fit
| Brand | Solo |
|---|---|
| Colours | Black, Burgundy, Dark Purple, Green |
| Frame size | 51-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 40 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
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 818
Pick the lenses that match your prescription:
- 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 40mm lens depth gives varifocal lenses plenty of room. 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 818 and checked by our technicians before they are sent out.
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.
FAQs
Can I get varifocal lenses in the Solo 818?
Yes. The 40mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Solo 818 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 51-17-140: 51mm lens width, 17mm bridge and 140mm arms, a medium fit.
