About the Solo 623
Solo 623 Prescription Glasses
An oval frame softens strong features and keeps the look light. The Solo 623 is a unisex full-rim oval frame, sized 51-17-135, in Deep Blue or Shaded Brown. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo collection.
Choosing your Solo 623 colour
Deep Blue. In Deep Blue, the frame is blue and crystal. It looks great with blue or grey eyes and pairs easily with denim and white.
Shaded Brown. Shaded Brown is a good everyday shade. It is a classic that looks relaxed and a little bit vintage.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Shape and style
Oval lenses balance square and heart-shaped faces and keep the overall look soft. 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 623 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.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Deep Blue, Shaded Brown |
| Frame size | 51-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 32 mm |
The 51mm lenses make this a medium frame that suits most faces. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
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 623
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.
The 32mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
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.
How your glasses are made
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Solo 623 and checked by our technicians before they are sent 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.
FAQs
Is the Solo 623 suitable for varifocals?
The 32mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I use the Solo 623 as computer glasses?
Yes. Single vision lenses set to your screen distance work well for desk work.
What size is it?
It is size 51-17-135: 51mm lens width, 17mm bridge and 135mm arms, a medium fit.
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.
