About the Solo 603
Solo 603 Prescription Glasses
There is something calm and classic about an oval frame. The Solo 603 is a unisex full-rim oval frame, sized 51-17-135, in Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo range.
Colour and finish
Blue. Blue is a clear, easy-to-wear blue. It looks great with blue or grey eyes and pairs easily with denim and white.
Why you will like it
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.
Decorative arms give the frame a finished, designer feel when you see it side on.
Whether it is your main pair or a spare, the Solo 603 is easy to live with.
Wearing it every day
Choose the colour closest to what you wear most and it will go with almost everything.
Frame size and fit
| Brand | Solo |
|---|---|
| Colours | Blue |
| Frame size | 51-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
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 603
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.
The 36mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
From our lab to you
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Solo 603. Every pair is checked before it leaves us.
Looking after them
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.
Your questions, answered
Can I get varifocal lenses in the Solo 603?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the Solo 603 as computer glasses?
Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both 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.
Where are my lenses made?
In our UK optical lab. They are cut to your prescription, fitted into your frame and checked before they are sent out.
