About the Solo 804
Solo 804 Prescription Glasses
A round frame is an easy way to add a little character. The Solo 804 is a unisex full-rim round frame, sized 49-19-140, in Blue, Crystal, Dark Purple or Demi. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Solo collection.
Choosing your Solo 804 colour
Blue. In Blue, the frame is patterned blue. It looks great with blue or grey eyes and pairs easily with denim and white.
Crystal. In Crystal, the frame is crystal clear. Because light passes through it, the frame looks lighter on the face and lets your features do the talking.
Dark Purple. The Dark Purple version is patterned purple. It brings a little personality without overpowering your features.
Demi. The Demi version is tortoiseshell. It flatters warm and olive skin and works with almost any outfit.
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.
The patterned finish means no two angles look quite the same.
If you want a frame you can put on in the morning and forget about, the Solo 804 is a strong choice.
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, Crystal, Dark Purple, Demi |
| Frame size | 49-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
With 49mm lenses, this is a compact frame that suits smaller faces. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 117mm.
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 804
Choose the lens type that suits how you use your glasses:
- 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. With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.
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
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Solo 804 and checked by our technicians before they are sent out.
Looking after them
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.
Questions we often get
Can I get varifocal lenses in the Solo 804?
Yes. The 41mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Solo 804 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 49mm lenses it suits smaller faces.
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.
