About the Matrix 842
Matrix 842 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Matrix 842 is a men’s full-rim rectangular frame, sized 51-16-140, in Black, Grey or Navy. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Matrix range.
3 colours to choose from
Black. Black is a deep, solid black. It is the safest choice if you only want one pair, and it never looks out of place.
Grey. In Grey, the frame is grey crystal. It is cool, modern and understated, and it suits grey or silver hair especially well.
Navy. Navy is a deep, dark blue. It looks great with blue or grey eyes and pairs easily with denim and white.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
The details
Rectangular lenses suit round and oval faces, adding a bit of definition. A crystal front looks modern and light, and it goes with everything.
If you want a frame you can put on in the morning and forget about, the Matrix 842 is a strong choice.
Wearing it every day
Short hair and a clean shave make the frame shape stand out; with longer hair or a beard it reads as more relaxed.
Size and fit
| Brand | Matrix |
|---|---|
| Frame | Full Rim |
| Colours | Black, Grey, Navy |
| Frame size | 51-16-140 mm (lens width, bridge, arm length) |
| Designed for | Men |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
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 Matrix 842
Choose the lens type that suits how you use your glasses:
- Single vision: one prescription for distance, reading or the computer.
- Progressive: near, middle and far in one lens with no line. (In the UK they call them varifocals.)
- Bifocal: a defined reading area at the bottom of the lens.
- Ready readers: simple magnification for close work.
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.
Ordering online is easier than you think
All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.
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 Matrix 842 and then sends your glasses to you in Australia.
Keep them looking new
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.

What size is it?
It is size 51-16-140: 51mm lens width, 16mm bridge and 140mm arms, a medium fit.
Can I wear the Matrix 842 for driving?
Yes. Single vision or progressive lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.

Yes. The 16mm bridge is designed for slimmer noses.
What does crystal mean?
A clear, see-through finish.
Where are my lenses made?
