About the Matrix 823
Matrix 823 Prescription Glasses
If you like structure but not sharp angles, a soft square is the sweet spot. The Matrix 823 is a women’s full-rim soft square frame, sized 52-17-135, in Black, Crystal, Purple, Tort or Wine. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Matrix range.
5 colours to choose from
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Crystal. In Crystal, the frame is crystal clear. It is a fresh, modern choice that suits almost any skin tone.
Purple. Purple is a rich purple. It adds a confident touch of colour and suits fair and cool skin tones.
Tort. In Tort, the frame is tortoiseshell. It warms up the face and sits nicely alongside camel, olive and cream.
Wine. The Wine version is wine red. It is rich and confident, and it looks stunning with dark hair.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. The crystal finish is clear and fresh, and it lets your features take centre stage.
Take a look at the arms: the detailing there is what makes this frame special. The patterned finish means no two angles look quite the same.
It is the kind of frame that works with most outfits, which makes the Matrix 823 an easy pick for everyday wear. Thinking of a second pair? The Matrix 823 works well as a backup.
Wearing it every day
Match the frame colour to something you wear often, such as a favourite scarf or bag, for a pulled-together look. Neutral make-up keeps the focus on your eyes.
How it fits
| Brand | Matrix |
|---|---|
| Frame | Full Rim |
| Colours | Black, Crystal, Purple, Tort, Wine |
| Frame size | 52-17-135 mm (lens width, bridge, arm length) |
| Designed for | Women |
The 52mm lenses make this a medium frame that suits most faces. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 823
Pick the lenses that match your prescription:
- Single vision: the same prescription from edge to edge.
- Bifocal: distance at the top and a reading segment at the bottom.
- Varifocal: a smooth change from distance to reading, with no line.
- Ready readers: a fixed magnification for books, phones and screens.
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.
How your glasses are made
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Matrix 823. Every pair is checked before it leaves us.
Looking after them
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
Your questions, answered
What size is it?
It is size 52-17-135: 52mm lens width, 17mm bridge and 135mm arms, a medium fit.
Can I wear the Matrix 823 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
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.
