About the Solo 816
Solo 816 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Solo 816 is a unisex full-rim rectangular frame, sized 54-17-145, in Black, Blue, Brown or Grey. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Solo collection.
Choosing your Solo 816 colour
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Blue. In Blue, the frame is blue fade. It looks great with blue or grey eyes and pairs easily with denim and white.
Brown. Brown is a warm, earthy brown. It warms up the face and sits nicely alongside camel, olive and cream.
Grey. The Grey version is black that fades to grey. It is a quiet, professional finish that works with navy, charcoal and white.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
The details
Rectangular lenses suit round and oval faces, adding a bit of definition. A soft colour fade defines the brow line and lets the lower half of the frame melt away.
Whether it is your main pair or a spare, the Solo 816 is easy to live with.
Styling tips
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Solo |
|---|---|
| Colours | Black, Blue, Brown, Grey |
| Frame size | 54-17-145 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
The 54mm lenses put it at the upper end of medium. 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 125mm.
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 816
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 36mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
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
Your Solo 816 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.
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 816?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 816 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 54-17-145: 54mm lens width, 17mm bridge and 145mm arms, a medium fit.
What does the colour fade look like?
The colour is darker at the top of the frame and becomes lighter towards the bottom.
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.
