About the FLEXIT 6043
FLEXIT 6043 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The FLEXIT 6043 is a unisex full-rim metal rectangular frame, sized 52-17-140, in Dark Gun. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Flexit collection.
Colour and finish
Dark Gun. In Dark Gun, the frame is gunmetal. It goes with almost everything and never draws too much attention.
Shape and style
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 6043 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Styling tips
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
Frame size and fit
| Brand | Flexit |
|---|---|
| Colours | Dark Gun |
| Frame size | 52-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 32 mm |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 6043
Pick the lenses that match your prescription:
- 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.
The 32mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
What you need to order
Have your prescription handy before you start. It will list the sphere, cylinder and axis for each eye, and often your PD as well. If your PD is missing, your optometrist can give it to you. Then simply choose your colour and lens type, enter your prescription and add any extras, such as a thinner lens or a coating. You can review everything in your cart before you pay.
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 6043 and sends the finished pair to you in Australia.
Keep them looking new
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.
Your questions, answered
Is the FLEXIT 6043 suitable for progressive lenses?
The 32mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I use the FLEXIT 6043 as computer glasses?
Yes. Single vision lenses set to your screen distance work well for desk work.
What size is it?
It is size 52-17-140: 52mm lens width, 17mm bridge and 140mm arms, a medium fit.
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.
