About the Solo 855
Solo 855 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The Solo 855 is a unisex full-rim rectangular frame, sized 53-17-145, in Black, Grey or Crystal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Solo range.
Choosing your Solo 855 colour
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Grey. The Grey version is translucent grey. It is cool, modern and understated, and it suits grey or silver hair especially well.
Crystal. The Crystal version is crystal clear. It blends in rather than stands out, which many people find easy to wear every day.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Why you will like it
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.
Because the colour is see-through, the frame has a light, glowing look.
Whether it is your main pair or a spare, the Solo 855 is easy to live with.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Solo |
|---|---|
| Colours | Black, Grey, Crystal |
| Frame size | 53-17-145 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
At 53mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 123mm.
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 855
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 39mm lens depth gives varifocal lenses plenty 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.
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.
How your glasses are made
Your Solo 855 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.
Keep them looking new
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 855?
Yes. The 39mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 855 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 53-17-145: 53mm lens width, 17mm 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.
