About the Solo 812
Solo 812 Prescription Glasses
There is something friendly and approachable about a round frame. The Solo 812 is a unisex full-rim round frame, sized 48-19-140, in Blue or Grey. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo collection.
Blue or Grey?
Blue. Blue is a clear, easy-to-wear blue. It brings a cool, calm touch of colour that suits most skin tones.
Grey. In Grey, the frame is grey and crystal. 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 812 design
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 812 is a strong choice.
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.
Frame size and fit
| Brand | Solo |
|---|---|
| Colours | Blue, Grey |
| Frame size | 48-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 43 mm |
At 48mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 115mm.
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 812
Your optician’s prescription will usually tell you which of these you need:
- Varifocals if you want to see near and far without swapping glasses.
- Single vision for one task done well, such as driving, reading or screen work.
- Bifocals if you prefer a clearly defined reading area.
- Ready readers for straightforward close-up help.
At 43mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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
Your Solo 812 is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.
Keep them looking new
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.
Your questions, answered
Can I get varifocal lenses in the Solo 812?
Yes. The 43mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 812 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
Is it a small frame?
Yes. With 48mm lenses it suits smaller faces.
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.
