About the FLEXIT 6046
FLEXIT 6046 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The FLEXIT 6046 is a unisex full-rim metal rectangular frame, sized 57-19-145, in Gold or Dark Gun. You can order it with single vision, progressive or bifocal lenses made to your prescription. It is part of our Flexit collection.
Choosing your FLEXIT 6046 colour
Gold. Gold is a warm, soft gold. It brings warmth to the face and looks lovely with gold jewellery or a watch.
Dark Gun. The Dark Gun version is gunmetal. It is cool, modern and understated, and it suits grey or silver hair especially well.
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
Rectangular lenses suit round and oval faces, adding a bit of definition. Metal lets the frame stay slim and light while keeping its shape.
It is the kind of frame that works with most outfits, which makes the FLEXIT 6046 an easy pick for everyday wear.
Wearing it every day
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Flexit |
|---|---|
| Colours | Gold, Dark Gun |
| Frame size | 57-19-145 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
With 57mm lenses, this is a larger frame that suits wider faces. The 19mm bridge is a little wider than average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 133mm.
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 FLEXIT 6046
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.
The 37mm lens depth works with single vision, bifocal and many progressive lenses. Stronger prescription? A high-index lens keeps things thin and light. An anti-reflective, scratch-resistant coating is worth adding too, especially if you drive 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.
Made for you in our UK lab
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your FLEXIT 6046 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.
Your questions, answered
Can I get progressive lenses in the FLEXIT 6046?
Yes. The 37mm lens depth gives progressive lenses enough height for all three vision zones.
Can I wear the FLEXIT 6046 for driving?
Yes. Single vision or progressive lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a large frame?
Yes. With 57mm lenses it suits wider faces.
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.
