About the FLEXIT 6039
FLEXIT 6039 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The FLEXIT 6039 is a unisex full-rim metal rectangular frame, sized 51-17-135, in Bronze, Gold or Lilac. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Flexit collection.
3 colours to choose from
Bronze. Bronze is a warm, brownish metallic finish. It is a warm, elegant choice that pairs nicely with earthy colours.
Gold. Gold is a warm, soft gold. It gives a polished, classic finish that never looks loud.
Lilac. Lilac is a soft, pale purple. It works beautifully with navy, grey and silver jewellery.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
About the FLEXIT 6039 design
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.
It is the kind of frame that works with most outfits, which makes the FLEXIT 6039 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.
Size and fit
| Brand | Flexit |
|---|---|
| Colours | Bronze, Gold, Lilac |
| Frame size | 51-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 33 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
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 FLEXIT 6039
Pick the lenses that match your prescription:
- 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 33mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. Prefer to keep things slim? Choose a high-index lens, which is thinner and lighter than standard. Then add an anti-reflective coating to cut glare from headlights and screens.
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
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 6039 and sends the finished pair to you in Australia.
Keep them looking new
Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
Your questions, answered
Is the FLEXIT 6039 suitable for progressive lenses?
The 33mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I wear the FLEXIT 6039 for driving?
Yes. Single vision lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-17-135: 51mm lens width, 17mm bridge and 135mm arms, a medium fit.
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.
