About the Zenith 106
Zenith 106 Prescription Glasses
Not quite round, not quite square, and that is exactly why this shape works on so many faces. The Zenith 106 is a unisex full-rim rounded square frame, sized 49-21-145, in Black, Crystal, Navy or Tort. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Zenith collection.
Which colour is you?
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Crystal. Crystal is a clear, see-through finish. It blends in rather than stands out, which many people find easy to wear every day.
Navy. Navy is a deep, dark blue. It reads as smart and dark from a distance, with a little more personality up close.
Tort. The Tort 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.
The details
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces. A crystal front looks modern and light, and it goes with everything.
Small metal studs at the corners add a neat, vintage finishing touch.
Whether it is your main pair or a spare, the Zenith 106 is easy to live with. The Zenith 106 also makes a handy spare pair for the car or the office. Thinking of a second pair? The Zenith 106 works well as a backup.
Wearing it every day
Because it is unisex, it is easy to share the look across the household. Pick the colour that matches your wardrobe rather than worrying about who it is designed for.
Size and fit
| Brand | Zenith |
|---|---|
| Frame | Full Rim |
| Colours | Black, Crystal, Navy, Tort |
| Frame size | 49-21-145 mm (lens width, bridge, arm length) |
| Designed for | Unisex |
With 49mm lenses, this is a compact frame that suits smaller faces. The 21mm bridge is wider than average, which suits a broader nose bridge. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 119mm.
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 Zenith 106
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.
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.
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.
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 Zenith 106. 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.
FAQs
Is it a small frame?
Yes. With 49mm lenses it suits smaller faces.
Can I use the Zenith 106 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.
Will it suit a wider nose bridge?
Yes. The 21mm bridge is wider than most frames.
Is it unisex?
Yes. It suits men and women.
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.
