About the Zenith 113
Zenith 113 Prescription Glasses
There is a reason square glasses never really go out of fashion. The Zenith 113 is a unisex full-rim square frame, sized 50-19-140, in Blue, Crystal or Purple. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Zenith collection.
3 colours to choose from
Blue. In Blue, the frame is translucent blue. It looks great with blue or grey eyes and pairs easily with denim and white.
Crystal. The Crystal version is crystal clear. It keeps the look soft and understated, and it works especially well on fair skin.
Purple. The Purple version is translucent purple. It brings a little personality without overpowering your features.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
The details
Square lenses add structure to round and oval faces and make features look more defined. 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. Tortoiseshell arms add warmth and a classic finishing touch.
The Zenith 113 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Styling tips
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 | Blue, Crystal, Purple |
| Frame size | 50-19-140 mm (lens width, bridge, arm length) |
| Designed for | Unisex |
With 50mm 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 119mm.
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 Zenith 113
Choose the lens type that suits how you use your glasses:
- Single vision: one clear prescription across the whole lens.
- Bifocal: distance on top, a reading segment below.
- Progressive: smooth vision from near to far in one lens, no line.
- Ready readers: off-the-shelf magnification for books and screens.
If your prescription is on the stronger side, a thinner high-index lens keeps the edges neat, and an anti-reflective coating means fewer distracting reflections on screens and at night.
Before you order
Check that your prescription is current; an eye test every couple of years is a good habit, and your optometrist will tell you how often you need one. You will also need your PD, which tells the lab where to centre the lenses so you look through the right spot. With those two things in hand, ordering takes just a few minutes: choose your colour, pick your lenses, enter your details and you are done.
How your glasses are made
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Zenith 113 and then sends your glasses to you in Australia.
A little care goes a long way
Wipe your lenses with a microfibre cloth rather than the hem of your shirt, keep them in a case when they are in your bag, and never leave them on the dashboard on a hot day. Our lens care guide has a few more habits worth picking up.
Questions we often get
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
Can I use the Zenith 113 as computer glasses?
Yes. Single vision lenses set to your screen distance, or progressive lenses if you also need distance vision, both work well for desk work.
Is it unisex?
Yes. It suits men and women.
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.
