About the Matrix 834
Matrix 834 Prescription Glasses
A rounded square gives you the softness of a round frame with a little more structure. The Matrix 834 is a unisex full-rim rounded square frame, sized 53-18-145, in Black or Brown. You can order it with single vision, progressive or bifocal lenses made to your prescription. It belongs to the Matrix range.
Black or Brown?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Brown. Brown is a warm, earthy brown. It flatters warm and olive skin and works with almost any outfit.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Why you will like it
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces.
The Matrix 834 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Wearing it every day
It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.
Frame size and fit
| Brand | Matrix |
|---|---|
| Frame | Full Rim |
| Colours | Black, Brown |
| Frame size | 53-18-145 mm (lens width, bridge, arm length) |
| Designed for | Unisex |
The 53mm lenses make this a medium frame that suits most faces. The 18mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 124mm.
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 Matrix 834
Your optometrist’s prescription will usually tell you which of these you need:
- 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.
What you need to order
Have your prescription handy before you start. It will list the sphere, cylinder and axis for each eye, and often your PD as well. If your PD is missing, your optometrist can give it to you. Then simply choose your colour and lens type, enter your prescription and add any extras, such as a thinner lens or a coating. You can review everything in your cart before you pay.
Made for you in our UK lab
Choose your colour and lenses, enter your prescription and PD, and our optical lab in the UK makes your lenses and fits them into your Matrix 834 before sending them to you in Australia.
Keep them looking new
Clean the lenses with lens spray and a soft cloth, fold the arms before you put them down, and keep them in a hard case when they are not on your face. Our guide to caring for your lenses covers the rest.
Your questions, answered
What size is it?
It is size 53-18-145: 53mm lens width, 18mm bridge and 145mm arms, a medium fit.
Can I use the Matrix 834 as computer glasses?

Is it unisex?
Yes. It suits men and women.
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.
