About the Solo 829
Solo 829 Prescription Glasses
Square frames add definition without trying too hard. The Solo 829 is a unisex full-rim square frame, sized 51-18-145, in Black, 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.
Choosing your Solo 829 colour
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Grey. In Grey, the frame is black and grey. It is cool, modern and understated, and it suits grey or silver hair especially well.
Crystal. The Crystal version is crystal clear. It keeps the look soft and understated, and it works especially well on fair skin.
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
Square lenses add structure to round and oval faces and make features look more defined. A crystal front looks modern and light, and it goes with everything.
The Solo 829 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Wearing it every day
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Black, Grey, Crystal |
| Frame size | 51-18-145 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 120mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the Solo 829
Pick the lenses that match your prescription:
- Single vision: one prescription across the whole lens, for distance, reading or the computer.
- Varifocal: near, intermediate and distance in one lens, with no visible line.
- Bifocal: a separate reading segment in the lower part of the lens.
- Ready readers: simple magnification if you just need help with close work.
At 41mm, 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.
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.
How your glasses are made
Your Solo 829 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.
Looking after them
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.
Questions we often get
Can I get varifocal lenses in the Solo 829?
Yes. The 41mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 829 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.
What size is it?
It is size 51-18-145: 51mm lens width, 18mm bridge and 145mm 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.
