About the Solo 815
Solo 815 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Solo 815 is a unisex full-rim rectangular frame, sized 52-17-140, in Black / Blue, 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.
3 colours to choose from
Black / Blue. The Black / Blue version is black and blue. It is the safest choice if you only want one pair, and it never looks out of place.
Grey. In Grey, the frame is translucent grey. It is a great match for cooler skin tones and a crisp, tidy look.
Crystal. In Crystal, the frame is crystal clear. It is a fresh, modern choice that suits almost any skin tone.
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 815 design
Rectangular lenses suit round and oval faces, adding a bit of definition. The crystal finish is clear and fresh, and it lets your features take centre stage.
The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
It is the kind of frame that works with most outfits, which makes the Solo 815 an easy pick for everyday wear.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
Frame size and fit
| Brand | Solo |
|---|---|
| Colours | Black / Blue, Grey, Crystal |
| Frame size | 52-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 815
Your optician’s prescription will usually tell you which of these you need:
- 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 37mm 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.
Ordering online is simple
You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.
Made for you in our UK lab
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Solo 815. Every pair is checked before it leaves us.
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 815?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the Solo 815 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 52-17-140: 52mm lens width, 17mm bridge and 140mm 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.
