About the Solo 811
Solo 811 Prescription Glasses
Round frames soften the face in a way square ones just cannot. The Solo 811 is a unisex full-rim round frame, sized 48-20-140, in Grey or Crystal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo range.
Grey or Crystal: which one is you?
Grey. The Grey version is black and grey. It is a quiet, professional finish that works with navy, charcoal and white.
Crystal. The Crystal version is crystal clear. Because light passes through it, the frame looks lighter on the face and lets your features do the talking.
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.
Shape and style
Round frames soften angular features, so they are a great match for square and heart-shaped faces. A crystal front looks modern and light, and it goes with everything.
If you want a frame you can put on in the morning and forget about, the Solo 811 is a strong choice.
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.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Grey, Crystal |
| Frame size | 48-20-140 mm (lens width, bridge, arm length) |
| Lens depth | 42 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.
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 811
Your optician’s prescription will usually tell you which of these you need:
- 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.
At 42mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots 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.
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 811. Every pair is checked before it leaves us.
Keep them looking new
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.
Questions we often get
Can I get varifocal lenses in the Solo 811?
Yes. The 42mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Solo 811 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
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 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.
