About the FLEXIT 6042
FLEXIT 6042 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The FLEXIT 6042 is a unisex full-rim metal rectangular frame, sized 52-18-135, in Blue/Silver or Bronze/Gold. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Flexit range.
Choosing your FLEXIT 6042 colour
Blue/Silver. Blue/Silver mixes blue and silver. It goes with almost everything and never draws too much attention.
Bronze/Gold. Bronze/Gold pairs bronze with gold. It is a warm, elegant choice that pairs nicely with earthy colours.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
The details
Rectangular lenses suit round and oval faces, adding a bit of definition. The slim metal construction keeps it light and neat, and it is easy for an optician to adjust.
The FLEXIT 6042 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
Frame size and fit
| Brand | Flexit |
|---|---|
| Colours | Blue/Silver, Bronze/Gold |
| Frame size | 52-18-135 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
The 52mm lenses make this a medium frame that suits most faces. The 18mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 122mm.
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 6042
Pick the lenses that match your prescription:
- Progressive lenses for clear vision at every distance without swapping pairs.
- Single vision for one job done well: driving, reading or desk work.
- Bifocal if you like a clearly marked reading section.
- Ready readers when you only need help close up.
The 36mm lens depth works with single vision, bifocal and many progressive lenses. 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.
From our lab to you
Once you have picked your colour and lens type and entered your prescription and PD, our UK optical lab makes your lenses, fits them into your FLEXIT 6042 and sends the finished pair to you in Australia.
Looking after them
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.
Questions we often get
Can I get progressive lenses in the FLEXIT 6042?
Yes. The 36mm lens depth gives progressive lenses enough height for all three vision zones.
Is the FLEXIT 6042 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
What size is it?
It is size 52-18-135: 52mm lens width, 18mm bridge and 135mm arms, a medium fit.
Where are my lenses made?
In our UK optical lab. They are cut to your prescription, fitted into your frame and then sent to you in Australia.
